For those metal clips the only reliable way to get those off easy is on of two ways. nice sturdy lift of the whole door card like you did or. If you do more in the future take a medium to large flat panel tool. Insert that tool from the outside push in down then small tilt. sometimes a pry tool just on the metal clip works better on some door for some reason. keeps the whole weather strip in place. the only hard on is near the vent glass. the rest are super simple. With that said a word of caution if done this way. Do NOT let the door fall. Learned from the experience of breaking that manual door lock rod right where it connects to the actuator. Easy to bend if it falls tool.

your last video of 2017 tahoe, made me think of something that happened to my 2025 buick encore gx. brought it in for routine oil chsnge to area garage, up till that point in the cars life nothing strange ever happened. when it was our turn car went crazy, and would not start and locked itself. had to use key to get insite. turned out the cart next to me had wires cut in antenna when winshield was replaced. it affected any car within around 20 feet of car with cut antenna wires. father then that car s were fine. owner of that car told garage anywhere car went same trouble. thought you find interesting

Never turn the show off. Your failure diagnostics are the star of the show. I used to work for a defense contractor (retired) and component level failure analysis was part of the job. Brake pads (meh) and engine misfires (ok) can be interesting, may or may not watch, but, the diagnostic videos are a sure bet. Be it a wiring problem, fuel system leak or a government snooping safety issue, I’m there. Also am a fan of RainmanRay. Ray is good, but (Ray you have your own strengths) needs to watch more of your diag’s. O. K, time to get off the soapbox and get on with the show.

Hi Eric, GM seems to like wire that work hardens and breaks, it would be fine for dash looms, but I can’t figure out why they don’t use a better quality of wire in the doors. I’ve had to repair broken wires in three GM vehicles, but always the front doors, to me this seems odd, how many damaged or broken harnesses have you found in rear doors The fact that they seldom get used in real life, makes a person wonder if they are not routed correctly or have been messed with previously. Have you seen this particular fault, on this vehicle type before Way to go GM

Did one of these on a Honda Accord for my mother, drivers side front door, two connectors at the door, every single wire was either completely broken, or hanging on by one or two strands. Couldn't get the harness, wound up de-pinning every single pin, and fixing the wires one at a time, then lots of fiddling to figure out what wire went where, because I couldn't find connector diagrams anywhere for it. Positive side, while it took me for ever to fix it all, it has been working for years now with no more problems.

This seems similar to Land Rover / Range Rover door locks where the internal motors stop working. Sometimes doors will unlock, but not lock or vice versa. In Land Rovers it is possible to just change the motors, but of course you have to take the lock apart.
I’ve just changed my alternator on my Jaguar XF and now the door locks will not work at all! This seems to be a common issue which requires some sort of Body Control Module reset which I’m waiting to have sorted.
Cars are great when they work!

My 97 Explorer did this, same door. A month ago, almost midnight, alarm goes off. I checked our CCTV and a guy was walking into our cul de sac, hoodie, backpack, mask. I grabbed the Mossberg and tried to find him but he made it over the 6 foot chainlink fence. Cops came and told us the neighborhood had several cars looted in past weeks. Fix on the X was a missing bolt on the solenoid. I thought about leaving it broken and sleeping in the car, with Mossberg, but I'm too old for that. Watching from Texas.

Okay usually when I finish stuffing my face with whatever percentage it is of what I've convinced myself is health food (salted for taste) that doesn't go down the front of my shirt, I stop watching and save the rest of the video for my next gorging. But I'm telling you this one had me on the edge of my seat and I couldn't stop watching, I mean the test just for poop and laughter changed everything and the next few minutes was legendary. Lady needs a harness. I hope we get a part 2.

Chevy door harnesses are Mexico and sometimes (Yazaki) was always Dominican Republic. Been to Lear, Yazaki, Sumitomo, Delphi (now Aptiv) all (except the Yazaki) was in Mexico. SOMETIMES the Door Harnesses are done by people like Saturn Electronics because they are considered a Minority Supplier and there is a required amount of content from them. Now. the Minority for Saturn LOL. HAWAII! Yep. Wish we could have done that trip to their corporate HQ. LOL!

I'm at 20: 52, I'm thinking the door has been tweaked just a little. I had a Chevy Malibu I bought used, the passenger side rear door the window would roll up and down just fine, you could open the door with the window all the way up or all the way down, but if it was down enough there was more than a 1/4 inch gap at the top and you opened the door, the window would shatter. The door was tweaked just enough it would twist the window when you opened it.

Seeing you struggle with the rear door lock brings back memories of the Mercedes W140 S class. Their door locks would get sticky and stopped working. It was fun sitting in the backseat of a $100, 000 car trying to get the door panel off on a closed door without totally destroying it. Those door locks were more complicated than a Swiss grandfather clock. It used mechanical, vacuum and air pressure to lock and unlock and operate the soft close.

Once again Eric O gives a master class in proper diagnosis. Eric O does not just swap out that bad part for the replacement part. Oh no, he just has to play with the old one after removing the inner door fascia. I love it when he finds the broken wire. I have learned from these many videos that a broken wire does not mean never works. There must be 100 SMA videos by now showing that a broken wire sometimes mean works intermittently'.

Had this issue with Nissans often enough that I would open the door to check if it lost/gained function of whatever circuit was involved. Fixed quite a few with new harnesses. Odd that it affected the LR door, the one that is least used. Yes, the hot glue or tape reclosing of the sealed box, you be surprised how many parts are opened just to find a broken old used part inside! Loved the video, brought back lots of not so good memories!

Watching the actuator die at that one specific door angle was the giveaway textbook broken conductors in the jamb flex point, and sure enough the harness was chafed to bare copper with the green twisted pair severed. The electronic child lock defaulting to its locked state when it loses power also neatly explains the no-open-from-inside complaint. Hopefully that harness actually shows up in a week for part 2.

I fixed all the power windows and locks on my old 98 Grand Cherokee, to fix the rear locks you have to replace the whole assembly, it helps to have small fingers lol. Nice to finally have it all working after many years of intermittent operation.
Note to all:
always check grounds for the power window modules!
PS old Grand Cherokee door panels come off real easy, just have extra retainer clips.

Damn, thought we were heading to Wilbert’s. Was thinking about Wilbert’s today. For the first time in years I found myself at a wreaking yard. Daughter’s Kia Optima had a rim with some corrosion not letting a tire bead fully. Tire store said a new rim was several hundred. I took a 20-minute ride and got one for $35. She is 16 and still feeling her way around curbs, no need for a new rim.

Rochester products made electric motors for everything for everyone in Rochester NY.
When GM was run by engineers they were going strong they used rubber to gasket their units.
When accounts lead GM used paper or sometimes pressure fit. then they outsourced it all to winkin, blinken and nod.
That stuff used to last, now.

This is the problem the manufacturer builds it just as cheap as possible. And the diagnosis is too expensive to be practical. Making the repair too expensive to be practical and replacement of the car too expensive to be practical!
So in short drive with that door problem until the the wheels fall of the car!

I had a ford F150 that had a plastic rod in the wiring harness through the door that was known for breaking and chaffing the harness to the door. would do an intermittent stage till it finally broke through. ford had plenty of those harnesses on the shelf so know problem but not worth a recall it seemed

26: 55 after breaking a bunch of plastic clips yesterday, and then having to throw an entire rear suspension back together just so I can wait for a part and do it all over again, it's nice to just sit back and watch and learn without it actually being my problem
