My driver's side rear door will not unlock. The lock mechanism had been squeaking a bit until it completely quit working.   What was the result? Replies to this message: kiawah (Feb 14, 2009 12:49 pm)

Hello, It sounds like the computer needs a reboot, disconnect the battery for 3 hours and reconnect. Let me know if that works.

Replying to: bigd35 (Dec 14, 2008 12:51 pm) You have to take the inside door panel off, and inspect all the linkages. Utilize the door handles inside and outside while you watch to see how the mechanism works, and then energize the electrics to lock and unlock.

I have a 2004 chevy tahoe with 48K. Today the service 4 wheel drive light came on. I read the manual and it said to shut it off. Restart and see if it comes back. It came back and the red light came on. Yellow lights flash and then goes back to the red. Does anyone know if this it the switch on the dash or the Encoder motor sensor.

Replying to: tahoefan04 (Jun 03, 2009 6:44 pm) the Chevy's are notorious for their push bottom 4x4 going out. It's almost always just the switch. Pull the front panel and put a new switch in and you should be good to go.
#7 of 9 2004 Tahoe: 20 AMP Fuse for rear doors and rear hatch blows by sfwoo Oct 05, 2009 (7:20 pm)
2004 Tahoe w/ 27K Miles. This is an intermittent problem at first, now it seems like everyday. When i unlock the doors with remote or manually the 20 amp fuse will blow. It only blows when I unlock the rear doors (pressing the remote twice) Had the car brought in to dealer when still under warranty. they checked it out and only replaced the blown fuse ($100.00). Told to bring it back if it happens again. Now the vehicle is out of warranty. Is anyone out there having the same issues. Replies to this message: kiawah (Oct 05, 2009 7:38 pm)

Replying to: sfwoo (Oct 05, 2009 7:20 pm) How long is it, between when you had it in for warranty repair with no trouble found (but replace fuse), and the problem now. If reasonably short period, they will most likely cover the repair.   Otherwise, if this was mine I'd try to determine whether the problem was in the locking/unlocking door solenoids (a defective solenoid), the wiring to the doors (like wires flexing in the door jamb shorting), the switch panel, or the control circuitry. Since it is failing pretty regularly, that should be easier to do....although a pain in that you'll have to take a bunch of doors apart.   Opening the doors up and unplugging the solenoids will help eliminate them, or prove they are the problem. You can meter out the switches, to verify that they are internally shorting. If the wiring is shorting out, then it is most likely at the drivers door jamp, which is the door that gets the most opening and shutting on vehicles. If none of those prove to be the problem, then suspect the control circuitry itself.
#9 of 9 Fuel Gauge by joewit Nov 23, 2009 (1:23 pm)
I have a 2004 Tahoe with 58,000 miles on it and I have had to replace 3 fuel gauges that stopped operating. Fuel gauge is not operating again. Dealer assures me they were defective gauges. Dealer replaced gauge in May. It became inoperative in early November. Are there any service bulletins on this?
