2009 Jeep Compass / Patriot Corroded Relay Box Repair / CEL P0480, P0481, U0100, P0691, P0693, C2202
This a video I tried to do a "live" diagnosis on just to show a little bit of the process of the repair this vehicle and diagnose it. I did jump the gun a little thinking I would have to cut the whole mess out of there but a new day with fresh eyes reviled only a few bad pins and was easily savable by using used parts. Why didn't I get a repair end from Chrysler? Its because they don’t make it unfortunately. I think all in all the repair went well and the customer was happy.

    What if I have that code but the fans are working properly. They even react to pulling the relays out and in.

    It's a Jeep….
    It's going to ALWAYS throw the WTF001 & FU002 codes

    Nice work Eric –O I always appreciate your video. I'm working hard here in Northeast Ohio, practicing the 500 most commonly misspelled words in the English language. _________ A lot of times for words like restaurant, I'll just lock it in with ( Texas Ashland University ) this helps me lock in the spelling correctly. To that end, I sometimes think of your humor, when you say I didn't get my ASE certification or my ABC or my qrx certifications. ________ I always remembered that from one of your videos.

    Very good job. Thanks for sticking with it.

    I don't believe in my 64 years and many cars and shops I ever had a tech goes to the junk yard and pull a part to fix my cars. EVER. It's either new or you go hunt buddy. You're truly a master

    Why the he'll would f.d.c. put an electric junction box so low on a "jeep"

  11. Avataaar/Circle Created with python_avatars 99bristol says:

    Can't believe can't re-pin the block

    I think you might want to get you a Bic lighter next time you're at the gas station to shrink your wire connections. That mini torch blows about twice the heat and flame needed to get the job done.

  13. Avataaar/Circle Created with python_avatars Robin Sattahip says:

    Fantastic Chrysler quality. She's lucky to have a mechanic willing to go to pick your part.

  14. Avataaar/Circle Created with python_avatars SHOTGUNJIM1 Items of interest says:

    These people need to learn not to buy these dam fiat jeeps. They can't build a car worth a dam, quality sucks. Jeep are not the same now

  16. Avataaar/Circle Created with python_avatars SuperDonaldduck007 says:

    FYI: The relay block is directly behind the wheel well. Remove the front portion of the plastic fender well on the drivers side, 6 connectors, and you have easy access to the relay block.

  17. Avataaar/Circle Created with python_avatars Kurt Cafini says:

    Really bad place to put a relay box!
    You would thing these engineers would be smart enough not to do things like this!

  18. Avataaar/Circle Created with python_avatars daveyio87 says:

    Thanks for this video. I watched it years ago and remembered it. I had a 2014 compass come in the shop today witht the p0480 and p0691 and i knew right where to look! (I'm a GM World Class Tech, and work on just about anything) You actually get your gm parts from my dealership.

    Helps out know what to look for thanks

    It’s time to stick a fork in it. It’s gone.

  21. Avataaar/Circle Created with python_avatars Bill S says:

    Thanks for the instructional videos mr.O there very helpful and inspirational. The dialog does add a personal touch to your videos. It gives us a glimpse into your personality , and your diagnostic thought train.

  22. Avataaar/Circle Created with python_avatars Albert Eller says:

    It’s Better to be Thurrell then to get haft the story. You are so good what you do and when you take a guess it is always be a educational guess.
    Great video Nice camera work. Thanks 🙏🏻

  23. Avataaar/Circle Created with python_avatars CitizenPerkins says:

    Wow! That was a pretty nifty set of fixes you made there! Kudos, sir! 👍👍

  24. Avataaar/Circle Created with python_avatars Geordo1960 says:

    Eric When I saw all of those trouble codes I felt a little anxiety. Amazing how you do not jump to all sorts of illogical conclusions and use your head and experience to solve a problem. It was really genius how you zeroed in on that problem so quickly. And really worked hard to find a viable and economical solution for the customer (not willing to just settle for the obvious solution of replacing harness and costing the customer a huge amount of money.) Your type of thinking and working teaches a lot about how to properly problem solve. Your technique applies to all sorts of problems.

  25. Avataaar/Circle Created with python_avatars Duane Donaldson says:

    Looks like somebody beat you to steal all the Chrysler Relays. I am happy you made that type of repair and you have some extra female connectors is ever needed. I hope you also charge for your experience even though you saved yourself a lot of time and could only charge for that actual time. Eduactional dialog is good, wire diagrams are better with dialog. Run to the junk yard is cool. Thanks for the salt test.

  26. Avataaar/Circle Created with python_avatars Paublus Americanus AMERICANUS says:

    You are really a good guy Eric O. I am saying this because of my experience with chrysler products people in my area. The cost and results are what has driven me to be self reliant. In other words to do it myself. The last fix I had ruined the engine. Sure they cleaned they car real nice but come on.

  27. Avataaar/Circle Created with python_avatars Joaquin Aguirre says:

    I like it! Good job friend, thanks so much. Have a good day.

  28. Avataaar/Circle Created with python_avatars Shane Harrison says:

    Very nice got right to it

  29. Avataaar/Circle Created with python_avatars Tachida Tumoto says:

    Dont get me wrong but…. why you dont repair just the 2 cables with a new pins or connection.. for me 2 cables sound better than 12 . Well that is my opinion .
    Btw I appreciate the video.

  30. Avataaar/Circle Created with python_avatars Erick Diaz says:

    Hello I have a 2016 Chrysler 300 that was jumstarted and after being jumstarted there was no crank no start after several tries the car tries to crank but no start and then eventually it will start air bag light is on codes are on for u0100 lost communication with pcm, c211b ignition run start imput circuit open, p0481, p0480 cooling fan and p258a electric vacuum pump circuit i think it's the pcm but wanted to know if you've seen this if you read this let me know thanks

  31. Avataaar/Circle Created with python_avatars Antonio Liz says:

    Exelent job, especially with the reconnection

  32. Avataaar/Circle Created with python_avatars Fern D says:

    Thanks Eric. I got a good deal on an 08 Compass with a tow package. It's a little workhorse. Please thank the lady whose 09 Compass you periodically work on. Don't overcharge her because after watching your video 1,000,000 times, I've saved a LOT of money and hopefully you're earning a few bucks posting fixit videos on YouTube. I'm still working on a speed sensor triple dash light after the mechanic changed out a hub. It looks like the sensor was put on correctly but now my abs light is on, with two others lights. I'm also working on a check engine light that traces back to the rear oxygen sensor. The sensor is new. I traced the wiring back to the relay box, like the one you changed in this video, and found one terminal which is corroded. I found the part on Amazon for $14, locally it's $24 but the terminals don't exactly match up. I'd have to change the female receptacle from narrow to wide, the same problem my old lady now has. Thanks again.

    I view videos like this before I buy a vehicle, then I try to make amends before I have problems.

  34. Avataaar/Circle Created with python_avatars Wayne S says:

    Eric, I think almost every one of these Jeeps has that relay issue. Just checked mine and the relay pin was rotted off too, cooling fan relay i think. Good show!

  35. Avataaar/Circle Created with python_avatars Roy Galambos says:

    Yes this 'style ' of video is very helpful in understanding the thought-process that leads to the most value for the customer. Thank you very much!

    Great job and video

    Second time watching 8/6/2020

  38. Avataaar/Circle Created with python_avatars ron klo says:

    Great video. I have a 2010 Compass with a constant P0480 code. Doesn't clear. I checked the relay box, all good.
    If I have the middle relay of the 3 out, and turn the ignition on, (but engine not running), if I plug in the relay or short the relay switch contacts, I hear a clicking from somewhere on the right side of the engine. Any idea if this is normal, or what might cause the clicking? With plugging in the relay, it clicks for about 2 seconds and stops. Because with plugging in the relay the clicking starts, the relay must be engergized. By shorting the switch contacts of either the other 2 relay locations (with relays removed) 1 or the other fan will run.

    I have JK error as p0693 like camshit sensor from should start

    Thank,s for the tip on ultra-seal will be getting some of that !

  41. Avataaar/Circle Created with python_avatars Paul Davies says:

    Hi Eric really enjoy watching you solve the electrical problems, wish I could have got you to look at my PT cruiser.

  42. Avataaar/Circle Created with python_avatars Nick Martinez says:

    Great video wish I knew some one like you !!

  43. Avataaar/Circle Created with python_avatars Elizabeth Maria Law says:

    I have a 2008 jeep patriot 4×4 automatic. My whole relay box was green not good. So I did go to pick a part and found a 2009 jeep patriot relay box all wirers matched except on my jeep I have two kg green wirers plus 3 little green wirers? That isn't on the one I picked up. So if I cut the wires from my old one and solder them together with on to the other same color wires! What do I do with the 3 little green wirers? And what are they for anyways? I do have a remote start in my jeep. But I have no remote for it. Please help me. I have a 2008 jeep patriot manual coming in mail. But because of the coronavirus it will not be here until june 11. 2020 .

    My brother own DoD 2010 avenger SXT. And basically it has a code po170 an po176. What advice that you recommend

  45. Avataaar/Circle Created with python_avatars Pat Jago says:

    I got so excited when you said “we going to the junk yard!”

  46. Avataaar/Circle Created with python_avatars Alborz Moghimi says:

    How do you get the smaller wires out of the relay?

  47. Avataaar/Circle Created with python_avatars Jose Condemarin says:

    Eric, repair was done the smart way. Good video and stop apologizing you always do great…thanks

  48. Avataaar/Circle Created with python_avatars Alan W says:

    What makes you solder a circuit versus the heat strink crimp? I've seen you do both in different circumstances.
