2008 JEEP WRANGLER - WIPERS TURN ON BY THEMSELVES DIAG & FIX 

The Jeep is a 2008 3.8L. My mistake! Sorry!

I have the same JEEP with the same problem. Where did you get the new instrument cluster from?

My wipers were activated but couldn’t alter the interval nor activate washer fluid; instrument cluster failed; the break lights were good and low beams were stuck on but no control over turn signals or high beams; radio good; could drive it fine tho. (Manual transmission). I tried removing negative cable but that only worked once. I tested all the fuses and they were good. I tried the hard reset for TIPM overnight it that failed. So I tried removing negative cable, left it overnight then reconnected it then did instrument cluster test. That worked. FOR NOW. If not, I’ll replace the instrument cluster.

Good job Mario! Another great video showing the importance of a good scope and knowing what the signal should look like! Thumbs up!

I have an 08 and it’s driving me nuts. The wipers will randomly move and it will kill the motor if I don’t turn the switch on and off and get them to bed themselves. No one can figure it out. It does it with the fuse pulled as well.

More proof that you need a scope or just do suspension work lol thanks again that place is lucky to have you work for them

Mario, I have a 2009 Jeep Wrangler and the wipers stay on just like the one in the video but my headlights also stay on without me turning them on and I cannot turn them off. I had to unlock the transmission to get it moved but was wondering if replacing the cluster would fix this problem also? Thanks, Rob

Mario thanks for your time and proffessional work. One question does the cluster needs programming or its just plug and play....once again thanks.

Mario where can I order the dash cluster and get it programmed

I don’t know if this has been asked before but I will ask anyway... My wipers go on intermittent as soon as I start the Jeep . Everything works normal at all speeds. Only problem is that as soon as I start the car the wipers go on intermittent. Someone has suggested that I change the wiper motor, what do you think??? The vehicle is a JKUR 2008.

My wipers come on randomly on my 2014 Jeep Compass

Great video Mario! Very good information. What size monitor is that on your Diag cart?

You are a great Macanudo on jeep Wear are you located I'd like you to look over my jeep My wipers and washer cane on for no reason took to garage fixed it but malfunction light still on

Is the rear light and the packing light too on down

HY MARIO FIRST OF THANKS FOR THE VIDEO , NOW ALL DIAGNOSTIC VIDEOS ARE GREATLY APPRECIATED . PLEASE KEEP UP THE FANTASTIC WORK BROTHER !

My wipers and wadher comes on out of mow whete

2008 jeep wrangler unlimited

Good to see a new video, you always do a great job. Glad I have a scope to see bus problems, use it more all the time.

Great video Super Mario 📉👍👏

Awesome job man

Afternoon SuperMarioDiag.......would this be an issue as well with a 2006 Jeep tj.....a d the wipers would not turn on?

First!

you tried sport

Having same symptom on a 2007 jku. How do I find a shop that can diagnose this properly?

Yo that 10 amp fuse that controls the wiper’s had nothing to do with it. Recommend testing the old one by putting it back in . Good video 🇺🇸

What do you think

it is beginning to happen randomly on my Jeep Commander 2006, when turning on or off the key...

Just seen the video my 08 wrangler does the wiper thing and the headlights are on but no lights on the instrument panel only way to make it work is to disconnect the negative battery cable and reconnect then runs fine

would the cluster cam bus affect ignition? my wipers will chatter on and you can feel the ignition stop

Wipers and exterior lights will be on, key on RUN position and there will be No a/c clutch engagement as long as cluster/CSS off line Quality diagnostics Mario

I had same problem, so I changed the windshield wiper switch and it fixed the problem, and it only cost me $99. Didn't need a computer nor anything, just a screwdriver PERIOD.

Awesome job man an sweet waveform. I honestly have no idea how people diag anything with out a scope these days but whatever......not gonna argue lol

Hay bud have you ever seen this? 2013 town and country comes in with a fan relay high code I believe (memory a little foggy). It's been bothering me for awhile. I turned it away a couple weeks ago but still baffled. The fans worked fine I can control them high and low from scan tool. The code only stores in the pcm not the tipm. If I remove the relay it will set in both tipm and pcm (same code). When I cleared the code it sets as soon as the fans come on when temperature hits around 220. As soon as it happens code set only in pcm not tipm fan works great. I scoped com lines, powers and grounds are all good (checking everything with fans running). Data pid in pcm for relay sw never changes. Now I can't see that fan relay sw pid in the tipm for some reason. It looks like the pcm is not seeing the fans take place. To be honest this is the second car I haven't been able to figure out and it drives me crazy. Did I forget something? Overlooked? Or just over thinking? I know tipms in Chryslers are junk but I refuse to replace something without evidence. Vans gone and most likely won't be back but for the future could I've done anything different. The other shop replaced all relays and a couple little things remember this was about 3 weeks ago. I hate when I can't figure it out but again time and money trumps curiosity. Any thoughts? My thinking is pcm because if the tipm doesn't set the code but I can make it with a real fault then the pcm is somehow bad. Van ran good no complaints other then engine light for expection

Nice work as always . Reminds me of the time Eric o disconnected a DORMAN part and the car went back to normal. 👍

Good job catching the ugly man 👍🏻 your rockin that pico bro

don't apologize, you do shit on your own time!

So the fix is just a cluster replacement?

Mario I really like your channel your a great guy but you got the title, year, and maybe even the engine size wrong lol from 2012+ they had the 3.6l

Great diagnostics Mario on the CAN bus. Keep up the good work! 😀👍

Awesome find Mario. Great diag. I never seen that before on jeep and i work on lot of wranglers. I am going to have to remember this one for sure. Its better to be busy at work all day then be slow.

Excellent video Mario! Love the hummingbird in the cluster!

Mario good video good troubleshooting. Nice find 👍

Thank you Mario. Good job. I appreciate your videos. Have a blessed and safe week.

Why did you check the low bus line instead of the high bus line. What do you set your meter on to check bus lines. Great video

thanks super! didn't know that would have thought it was a motor board

As always, a great video. I have never seen can/bus waveforms like that. Thank you for sharing

What kind of tool did you use to diag this?

did you have to programme the new cluster,,,i from over the pond so its always interesting to know,,,keep up the good work

As always great video bro. Keep them coming! Btw new mic?

Cool video keep up the good work.

Show how to change it! Please

Great video ! Thx subbed!!!

Thanks Mario that was a great find and also educational. Appreciate all that you do.

crazy that's about all i can say

we need more techs like super Mario

You know I'm copying that diag cart? New cluster or rebuilt the original?

Great video! thank you! I have a question do you need to program this new cluster to the PCM or BCM? Or is just plug ang and play

Great information thanks, do you still use the Micsig scope.

Good call there buddy.

Great find, thx for sharing.

Another great video, thank you Mario!!

I like the video

super video and super diagnosis.

Great video Mario! As always enjoy watching your videos. Thanks for taking the time.

How do you know when to diagnose from can bus low ref or high ref or it doesnt matter as long as your on a bus line . ThNks

Great find!

Looks like a fix. Thanks!

Great job sir 👍

FIRST HAHAHA GOOD VIDEO /INFO AND ANY CODE IN THE SYSTEM AND DID THE CLUSTER NEEDED PROGRAMING. CHEEEERS

Mario, thanks for a great video. Have you seen where the headlights turn on automatically without the ignition key in? Parked outside and it is as if someone pressed the button on the key fob but I am sure that no one did because i had the key in a box. Would love to hear is someone has found that issue. Thanks in advance

Do you think you would get the same bad CAN pattern at the DLC pins?

Great video, good find!

nice one, Mario

Do you know why the waveform has those spikes high and low?

Was the Voltage average on the can signal the same with the cluster plugged in and unplugged?

Nice find.👍👍

nice shot !!!!! 💪🏻

It doesn't need to be program?

Great diag, Mario. Impressed. Sure there was a lot more work and head scratching that went on before you filmed this video, would love to see some vids from the time when the vehicle is presented to the stage of diagnosis to show how long it can take to pinpoint a fault. Great work, sir!

👍

Great Job!

Great job as always!
