    Driver door lock and windwos wont work sometimes...(SOLVED - so far)

    I forgot to make photos. But the spot where the insulation was broken was right behind where the harness goes into the door - on the door side. I had to pull the wire out a bit to see it. @exp500: screwdriver?

    Driver door lock and windwos wont work sometimes...(SOLVED - so far)

    Final update: As this issue really pissed me off I just opened the complete harness from the latch to the plug in the dash. There were 2 cables where the isolation was cut. not cut through - just a little cut in. And when these touched each other all the problems appeared. Put new wires in -...

    Driver door lock and windwos wont work sometimes...(SOLVED - so far)

    ...story goes on: today (hot outside again) it started again! But this time differently: when I open the door and close it ONCE - it says "Driver door open". When I open and close it for another time - it works. and so on and so on. It ALWAYS only works the second time.... What the heck...

    Driver door lock and windwos wont work sometimes...(SOLVED - so far)

    ok. looks like I have to take off the door panels and take a closer look. As it sometimes works it might be just "stuck"?

    Driver door lock and windwos wont work sometimes...(SOLVED - so far)

    UPDATE: now as its getting very hot outside the issue came back. The display says "driver door open" when the door is closed and that causes all the other issues. Sometimes in the evening when it cools down a bit AND if I close the door very softly the truck thinks the door is closed. When I...

    Driver door lock and windwos wont work sometimes...(SOLVED - so far)

    Hi there! Today it started again. So I first opened the door and sprayed some WD40 into the latch. Then everything worked fine again. I don´t know if that solved the problem permanently, but if so, it could have been a stuck wheel inside the latch. I think there is a gear wheel inside that...

    Driver door lock and windwos wont work sometimes...(SOLVED - so far)

    Hello! My 2010 GMC Yukon Denali has some issues with the driver door. It started 2 weeks ago (when it became hot outside). Sometimes the door wont lock (neither with the remote nor with the switches inside). When this happens all the switches in the door panel (windows, mirrors etc...) wont...

    Park Sensor numbers? 1 to 4?

    Last issue: Head Unit switches to "Video in"

    UPDATE: found the rear speaker wires. but there werer separate tweeter and bass wires. So I plugged in a denoiser-device right behind the headunit - and the noise was gone. BUT: These days I figured out that there is still a buzzing noise when I switch on the heated seats. And then I decided...

    Last issue: Head Unit switches to "Video in"

    ok. the power button didnt make any difference. This should switch off the rear speaker, shouldnt it? It might be, that the head unit doesnt support the rear enterteinment system. But as I said: the noise only comes from the speakers that are still attached to the amp. I definitely need to know...

    Last issue: Head Unit switches to "Video in"

    no. that whine is gone when I connect the factory head unit. And before I bypassed the front speakers I had that whine in the front, too. I had the same issue with my 2005 Tahoe and aftermarket radios with BOSE AMP. So I think prying the pins would not helpt, would it?

    Last issue: Head Unit switches to "Video in"

    Well now, here is my workaround. As it seemed that it was an issue with the serial data line from the yukon to the aftermarket radio I wont use the automatic rear camera activation. The truck always activates the camera and always sends a message to the head unit. But I could deactivate the...

    Last issue: Head Unit switches to "Video in"

    ..and hook up this wire with what? There is no "reverse in" on my head unit as all this info comes from the can bus through the serial wire at the main harness.

    Last issue: Head Unit switches to "Video in"

    UPDATE: I checked the wires of the dash-sided camera harness. the green/white has 12V as soon as I plug in the radio and keeps the 12V all over the gears. When I jump that wire to another (except drain wire and ground of course) nothing happens. Still the same thing: The head unit switches to...
