Chevrolet S10 Vacuum Leak Repair

For quite some time, my truckling has been suffering from a vacuum leak that would sometimes make the climate controls not work (especially under hard acceleration--needed to keep after the Keykeeper's supercharged Pontiac!). Also, when the engine was off, airflow would revert to the dash vents due to vacuum loss. (GM vehicles have a failsafe position that is a mix between the heater outlet and defroster vent. Why mine went to the dash vents I don't know.)
If you are not able to switch between HOT and COLD airflow, your blend door actuator has probably failed. On a 2003 truck and probably anything 98-up, the blend door is operated by an electric motor. Failures are usually due to one of the gears stripping out or cracking. If you're faced with this repair, you may find this video from RU-vidr Steve Crosier worthwhile: • Blazer Jimmy Blend doo...
A number of people have indicated that the vacuum line going down into the fender well area connects to a vacuum reservoir. I never had to troubleshoot that and can't speak to where it goes.
As of April 2013, I don't own this truck any longer. Anyone seeking detailed service advice about this or any other repair should get the GENUINE GM FACTORY service manual. Do NOT waste your time or money on the Haynes or Chilton's manuals -- they are just about worthless.

hey ya wanna know a REALLY fun repair job? the heater core went out on my dad's 2001 chevy s10 last christmas and me and him had to strip the WHOLE ENTIRE dash outta there just to get to that stupid heater core, that was the most fun we evar had workin on a vehicle

@BIGW0RD 12 лет назад

do you know where that rubber hose runs to down the fender? the one on my s10 blazer came off and i cant find where it goes to. any help?

@iCanSpoiL 12 лет назад

Thank you for this video! I just bought a 2003 s10 yesterday, and on the ride home from the dealership I noticed that no matter where I set the vents to blow, they'd always continue to blow out of the dash panel. I did some research online and found out that it may be due to a vacuum leak, and then I found your video that shows the exact same problem! I'm going to go take a look at it right now and see if the hose is torn. Thanks again! +1!

@tonytune4342 9 лет назад

Thank you so much. You gentlemen saved me a bunch of money. My problem was exactly the same as yours. Thanks to you, I was able to fix it myself. Keep up the good work.All of us non mechanic guys need guys like you.

Note do not use motor oil as lubricant on rubber hose it will break down the rubber making it not last as long.

where does the other hose go to?? i replaced the one for climate control and from/to block/tee but the other hose isn't attach to anything??

@barbarabarfield7058 9 лет назад

Tyler McGonigal the hose will go to the vacuum connector- it goes to the hose barb under the breather (you just pop the breather off using a spring loaded clip on the back side under the edge of the breather--and remove a couple connectors and then you can see where it goes under the breather/intake )where it gets its pressure from the engine and the white things are also hose barb connectors you can get at any autoparts store usually 8-ten different sizes and shapes straights-tees-l's ... for about 5 dollars.www.autozone.com/fittings-and-hose-line-connectors/vacuum-connector-and-tubing......this is all I know without seeing the video or having the manual in front of me...hope this helps.

@ZANL188 9 лет назад

Didn't even know I had this problem on 2003 Sonoma until I saw this video. Sure enough I checked the hose and it was dust! Defrost burns me out now. Thank you.

@uxwbill An airbag will not harm a properly belted adult. My mom was in a crash when the airbag in her '95 Jeep Grand Cherokee deployed and all she got was a little scratch on her chin. This was with the early full-power Chrysler airbag design, too. Since 1998, automakers have used smaller "depowered" airbags.

@twstf8905 6 лет назад

OMG Watching this and I go out and check and all three of the vacuum lines coming off of that T thing on my truck were rotting and crumbling away! Now, I just gotta go get new vacuum lines and fix it, (apparently, I'm not the only one saying THANKS lol)

@vwestlife 13 лет назад

@uxwbill My 1997 VW Passat has a variable displacement A/C compressor. But then again it also has drive-by-wire (the accelerator is merely a potentiometer), so Volkswagen was pretty far ahead of their time back then. My Mazda, which is over a decade newer, has neither of these features!

@patr10t762 7 лет назад

Thank you for the tutorial, it really saved the day. This saved hours of aggravation. I googled the symptoms and your video came up. I watched it and didn't bother looking at any other information went to the truck and touched the line only to have it disintegrate. Went to my parts store and asked for a couple inches of vacuum line and picked up a couple other things and got the line free. Put the new line on and mama (and state inspector) will be happy. A quarter million views! You can figure that's the amount of hours you saved with this video. Again Thank You!

@davedruda 11 лет назад

Hey, thanks for the video. I had no idea what was causing my weak airflow out of the vents. I stumbled across this video searching for advice on freon psi. After watching I replaced both the long piece (7/32 width hose) and the short piece (5/32 width hose). Then added about 1/3rd of a can of freon. For about $25 total - with a lot of leftover hose - my AC is stronger and colder than ever. 2002 2.2l 4cyl. Chevy S10 Pickup. 145k miles. I really appreciate it.

@ScottyKUtah 11 лет назад

Last week I noticed that I had no air out of the defroster or floor. I originally thought it was something mechanical. Thanks to your video I discovered the hose from the right side all the way to the middle of the engine was dryrotted. Got a new hose in, but busted that tiny hose you commented on. Thanks to duct tape and that valve piece, I have full air in all positions again. If you are ever in Oklahoma I'd like to shake your hand and buy you a beer!

@vwestlife 13 лет назад

@uxwbill In the event of an airbag deployment, the collision damage would most likely be significant enough that you'd be replacing the entire truck, not just the airbag itself!

@megaloogy 8 лет назад

I've owned a 1995 GMC Sonoma and now a 1999 S10 and I always thought it was peculiar that the little 4 bangers had the same response to climbing a steep hill with the gas to the floor. The air flow would always switch from defrost to dash heat. Recently the defrost stopped working altogether. I saw your video and checked the tubing you demonstrated and sure enough it was rotten with a hole in it. Has to be the easiest you tube fix I have ever had. Never dawned on me that vacuum was even used anymore. Thanks for posting.

@cmannphoto 9 лет назад

Thanks for this video. I watched this video last night, went out this afternoon, popped the hood on my '98 S10 Blazer and in the exact same place by the brake booster my vacuum lines were collapsed from the engine block to that same TEE and to the left fender (were does that go anyway?). So I replaced 2 foot of 7/32" hose and about a foot of 5/32" hose. All for less than $5 in hose. Thanks again

@curtissmith5924 9 месяцев назад

Thanks for the video! I found the broken vacuum line a couple weeks ago, but didn't realize what its purpose was. I also was trying to figure out why my selector was not working, but this video saved the day. Thank you!

@allentig 9 лет назад

just bought the....hell i forgot what i bought....haha... think it was the 7/32 and the 5/32 vac hose, in a prepackaged form at Oriellys. didnt quite understand the whole deal from your video, but i figured it out, got all three lines replaced.... fan freakin tastic! i actually can switch air to anywhere i want again!..... ty ty ty ty ty..... i cant believe how rotten that hose was..... still not getting quite as much heat as i should..... the heat control does work, but doesnt get quite as hot as it should..... next step, flush out heater core... when i get a round tuit ...

@yrufatman 9 лет назад

Thanks for this video. I had exactly the same problem, ordered my actuator, was taking all the under dash parts apart prepping for when the part come in. I got aggravated as the area is to darn small for me. So I come in and was going to try youtube one more time for maybe another fix and I found this. Watched it, went back out, had the same rotten vacuum line that you showed. Went to Advanced Auto, got me a 2" piece for like .60 cents, put it on and it did fix my problem, so got my money back on the actuator, not to mention, they ordered the wrong one anyway.

@bill5407 8 лет назад

Thanks Much!! This was exactly my problem.

@joew9392 7 лет назад

Same here. I replaced the short hose but the one going toward the fender really looks bad, would like to replace it if I knew how to find the other end.

@joew9392 7 лет назад

Never mind, I found the other end but it was kinda hidden behind the anti-lock stuff. It just fits on a little nipple going to the vacuum reservoir behind the fender but it sticks out enough to stick the hose on it..

@idontknow19841 12 лет назад

so after completely undoing most of my dash underneath i find this post... yep its 2 am and im outside under the hood in my robe and i find 3 completely rotted vacuum hoses which is keeping my ac from doing anything other then blow on all three areas... will let you know the outcome after a visit to autozone in the morning

@raywood8187 6 месяцев назад

I still don't know what the real purpose of that line is. My actuator to change the vents wasn't working, I found that hose just hanging and since I didn't know where it went, put a plug in the end of it and that fixed my actuator. Now that I know where it goes, I tried connecting a new piece of hose to the nipple but it just fell right off again. I don't know if the nipple is bad or what but it's impossible get inside to do anything so I guess I'll just plug the line again.

@compactc9 12 лет назад

Seems that the brake booster area hoses like to leak, thankfully its usually easy to get to. My last Durango had a stuck blend door, probably a leaking hose to one of the vacuum servos under the dash, and the heater core was bad. Was dreading the repair, but in a bittersweet turn of events it ended up getting totaled. My year newer (2001) Durango now has a lovely mess of wires instead. And thankfully no leaks!

I know that this is old, but still very good information. I just walked out to my son's Chevy S-10 and the vacuum hose was in the same condition as yours! The A/C now switches the hose was long enough to cut off the bad and reconnect. It looked as though mine had too much slack and caused the hose to have a force bend in it. Thank you ever so much!!!!

@TutorialPanda 12 лет назад

Oh and the line that you were tugging on at 6:22 goes to a little plastic block, i was stuppied and pushed the break booster out of the way and all the crap just to fine that inside the double wall is a little plastic block :/ all you need to do is get a flash light and look into the fender from the engine compartment, and just follow the line, trust me, if you have any issues i can make you a video :)

@fredde94chr 13 лет назад

@uxwbill Well, i can't really test it... it's a 450dollar car, in very good kondition, no rust or such... Iam bringing a mechanic to take a look at it. It dont start since the fuel pump is broken and some other stuff that nees to be fixed! So then, do you think my mechanic can take a quick look to see if it's really the fuel pump and nothing else? Is it easy to notice if it's really the pump? Sorry my english isnt the best! I hope you understand what i mean!

@mjmcomputers 13 лет назад

@uxwbill Actually on the old systems before they had the orifice tube and pressure switches. They had an expansion valve that would open and close between the high side and low side to regulate pressure, and cause the freon to cool as it passed through the expansion valve. On those systems when the ac was on the compressor stayed on all the time. But yeah any modern system cycles the compressor.

I literally have the exact same issue with my 1998 Chevrolet s10 2.2L. I am having a hell of a time though attaching to the tiny hose that disappears into the truck. I have no issue connecting the new hose to the T but it is the small connecter that is an issue. Did I loose a piece in removing the original dry cable? I looked but did not see any parts fall through the hood. Should I just use a clamp on it to seal it if I did lose a piece? Any input on this is appreciated.

@uberdork2 10 лет назад

@TylersNeighborhoodGarage 13 лет назад

@uxwbill William, just a heads-up...some of the newer GM AC compressors do run full time. They are known as variable-displacement. Simply put, the compressor constantly adjusts it's output pressure internally and does not cycle the clutch. Also some AC systems that use an expansion valve instead of an orifice tube run the compressor full time.

On my 97 and 98 Lesabre the module was behind the glovebox. (probably there on the Bonneville too) They contain solenoids which directs the pressure. It's well noted that the nipples on those style modules tend to get soft over time and lose vacuum pressure. Also the harness itself might begin to leak. Luckily, I was able to go find a decent module out of a junkyard for $8 (AC Delco wants $450 for a new one.)

I got a 97 blazer and had the same problem a while back. I was glad I just need to replace an easy vacuum line. Some fixes are easy.

This video was a life saver for me. I thought that the guys at Best Buy knocked my lines off when they put my new radio in during the summer. Before I went there to complain, I looked under the hood, and just like in this video, that hose was rotted. I replaced it and the other short one. The long one will have to wait, but my controls are working again. Great video guys. Thanks.

thank you for this video, i had the same problem with my 1999 chevy s-10 pick up truck, that vacuum line with the tee connection coming from the wheel well was so corroded.. the moment i touched it, it turnt to dust... :) i bought replacement vacuum hose and fixed it myself for under $9.00 .. THANK YOU ONCE AGAIN..

Thanks a million. Same exact problem that you had. I was giving serious thought to selling my S-10 truck (13 years old), versus paying a garage or trying to tear apart dash and fix myself. I actually replaced all vacuum hoses going to the T-fitting and HVAC works like a champ. Cost me under $10. Thanks again for posting the video.

i had same issue was but in my case the vacuum leak was causing 4x4 not to engage on my 01 zr2 blazer. And FYI The line that goes into the fender goes to the evap canister.

I've got a 01 blazer and I've got the same problem and now I think I know why, on that t joint where 3 hoses connect mine only has 2 houses on it 1 that goes over the top of the brake booster and another that comes out the side of the fender area my question is where is that other hose come from that comes from the front past the fuse box? 8ve searched everywhere and cannot find the 3rd hose that connects to that t joint, it would be a huge help if you could tell me.

Bill, my 99 Ford Ranger does this also, but under hard acceleration, the vents just close and stop blowing at all. And the truck does not idle down like it supposed to, it takes a little bit for it to get back down to idle after you push the clutch in, I have not looked into it too much for the fear of tearing the whole thing appart. But I think tomorrow I'll give it a visual look over to see if I'm as lucky as you were!

@sblrealtor 9 лет назад

You guys nailed it! I had the same problem. I was fortunate enough to watch your video after the one where you tear out the truck interior to get to the actuators. My lines were rotten and I still havent found the other line that six inch line goes to off one of the tees! previous comment said its in the fender weld somewhere so I'll check that but thanks again

Hey uxwbill, This is just a question that really isn't related to the video, but I figured I could ask anyway. Have you ever heard of not being able to put a donut size spare tire in front if the car is front wheel drive. I was told that can damage the transmission? Any ideas.
