I had / have this exact same problem. Fan only works on high. Repair shop replaced the resister and it worked two days, then back to original failure. Shop replaced resister again thinking it was defective. Failed again two days latter. I'll try to fix it myself and will post the fix if I can figure it out. THANK YOU for the nice suggestion, glad it worked for others !!!
@@chriscodrington5464 Hello Chris. Sorry but I haven't done any troubleshooting yet 😞. Guess I've just been too busy with other things now. Best of luck to you!!!
Good looking out im a DIY guy i had this problem for weeks And I could figure out the problem with it i RU-vidd it couple times but I couldn’t find a solution Till i Have across Your Video Good Work 👍🏽
These poor resistors have a hard life. To survive, they need the slot in the air stream to be cooled. A bad design, but not only from Ford ;-) Thank you for sharing. Cheers Bernd
@@cheftush Ended up saving me $500 on a used 2010 F150 I just picked up. After test driving it I googled the issue and watched your video. Then went to the dealer and negotiated the price down $500 due to the fan issue for a $15 dollar fix.
Hello, my Husband just called me from work and he is telling me his AC will not turn at all. Do you think this could be the issue? I had him try all of the fan speeds and none work. It did this morning.
Would this be the fix if… I will turn on the AC it works fine and then the blower start slowing down kind of a puttering to a stop. I’ll turn the unit off and then a couple minutes later turn it back on and it will work fine and then the fan again will slow down puttering to a stop.
Does anybody have this issue with the fan just slowing down. Starts high, and then just over a couple of minutes just slows to nothing. Would the resister possible work for this?
mdaycoc I had done some reading up on the Ford F-150 forums and this seems like it's a pretty common issue. So, I took a low risk chance and ordered the part. If it was a higher dollar fix, I would have pulled out my meter and done some electrical diagnostics but as it was it turned out ok.
Didn't fix mine, blower went out after getting a new battery. Weird I know. It looked burnt up so I figured it was the culprit but still not working. Blend door thingy is next to replace. 2nd one on my 2011 f150. Trying everything before I drop 150 on a new blower motor.
I just went through this with my 06 0 lariot do yourself a favour don't bolt the new resister in u can check it not bolted up in my case the blower only worked on high i pulled the resister it still would only work on high I bought a resister from canadian tire 60 bucks tried it same thing dammm i took it back and bought one from amazon took 3 weeks to get pluged it problem solved. resister from crappy 9 bucks on line those 10 mm bol a little tricky i was going to pull the glove box but didn't
@@cheftush I took it out and hooked it to 12v and it spun good, at first it would lag on speed 1&2 then fully stopped, the resistor I took out looked burnt up so I really thought that would be it. With the new resistor it turn on for like 4 seconds then never turned on again
Usually you will still have at least one speed on the fan so I’m not sure the resistor is the issue. Having said that, it’s easy enough and cheap enough to replace and cross it off the list off items to check.
