Good afternoon.  I am experiencing weird issues with my rear power windows on both drive and passenger side.

both rear windows will roll down, but not up with their own window switch in the back doors.

i can (intermittently) roll them up with the master switch on driver door.  the other day, i couldn't roll the passenger rear up at all.  i ended up opening and closing the rear door, then i could roll the window up.

 

any ideas on what i should start looking for?

 

Appreciate any help.  thank you

it may be broken wires in the conduit between the door and the body, most likely the drivers door as that sees the most use. slice the rubber conduit with a razor knife and inspect the wires. you may need to pull on individual wires as sometimes the wire breaks but not the insulation .if the wires broken the insulation will stretch when u give it a tug. all the windows rely on the wiring to the master switch for power. if you find broken wires solder them back together and shrink tube them

thanks for the insight.  i will investigate and report back.  it may be a few days - but I will report my findings

so, i have yet to investigate this.  sorry for the delay.  i just have been taking my chances with the windows rolling up or down.  I am ready to explore this.  I have a question first, might seem dumb, but if I cut the rubber conduit what happens if:

  • I find the wires are fine?
  • How do I reseal the conduit once cut?

There is another post from the past couple days that has a utube video of repairing the switches. You might want to try that first

sorry for the no reply.  yes - i did solve this problem this past summer.   I did have a broken wire in the wire harness that runs thru the driver door.  if i remember the wire was green.  that didn't fix my problem, however.  I ended up replacing ALL window switches in all 4 doors.  problem has since been gone.

    • Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆
    • I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death. 
    • In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them. 
    • I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.     
    • Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.
