#18 of 25 1990 Suburban Tailgate by sellis1053 Feb 16, 2008 (2:38 pm)
I have a 1990 Suburban with a tailgate. The window rolls up and down fine, but the tailgate won't completely unlatch. As you're looking at the tailgate from the rear of the vehicle, the right side unlatches but not the left. I can't get to the screws that hold the inside panel onto the tailgate. Any thoughts?

Replying to: pete43 (Oct 13, 2007 11:53 am) I have been experiencing the same problem with our 2003 Tahoe. When the dealer first diagnosed this, they replaced the fuse block. Shortly after that, the problem resurfaced. The second time it was in the shop, they replaced the rear door lock relay. Now, approximately 60 days since the last repair......same problem. It seems the problem is somewhat intermittent, I've tried trouble shooting it myself by using different remotes and changing the lock settings on the driver information center, all to no avail. I can get the rear doors to unlock while sitting in the drivers seat, start the vehicle, close the drivers door, activate the lock button on the drivers door and repeat the lock, unlock sequence a couple of times and finally the rear doors and hatch will unlock. Anyone else out there equally frustrated?

Replying to: jtdeerslayer (Jul 14, 2008 3:16 pm) Since my posting on May 13th, the Tahoe went back in the shop at the Chevy dealer on May 15th and they finally determined the problem was caused by a defective Left Dash Fuse Block, GM part # is 15266954. It has been 60 days since they replaced this part and I have not had any problems with the locks since then. I am not positive that is the part number, I'm taking the information from the repair invoice so it should be accurate. Hope this helps. Good luck!
#22 of 25 Re: Remotes abruptly stopped working by mlingga Oct 09, 2009 (12:49 pm)
Replying to: jtdeerslayer (Jul 14, 2008 3:16 pm) I'm resurrecting a thread that is closest to my issue that I could fine. Abruptly, our 2007 LT stopped responding to the remotes. One remote fails to lock or unlock the doors. The other will sometimes lock, but never unlock the doors. It's not 100% of the time. For example, once I manually unlock the door and get in, the remote works from inside the vehicle. I have also repeatedly tried to use the "reconnect your remote" feature off the data display in which you hold down the lock and unlock buttons til it beeps. It does this fine, remote seems to work, but a few hours later it's back to not working. I replaced the battery on the unlikely hope that was the issue but no improvement. If this were a computer, I'd reboot the thing. Any ideas? Replies to this message: kiawah (Oct 09, 2009 1:57 pm) mlingga (Oct 09, 2009 7:36 pm)

Replying to: mlingga (Oct 09, 2009 12:49 pm) My guess is it isn't your remote keyfobs, because all your remotes fail.   The remote control door lock receiver is back in the rear corner garnish molding, but I suspect you're going to need the dealer to diagnose this problem with their diagnostic controller. And they may need to reboot your computer. Take all your keyfobs.   Is your vehicle still under warranty?   I guess the one thing you could/should check, is that the vehicle battery is at full voltage and clean corrosion free connectors.

Replying to: kiawah (Oct 09, 2009 1:57 pm) kiawah: yeah, I agree, much to my regret it really has to be the vehicle, not the fobs, since they both stopped working simultaneously. Warranty went out a long time ago, battery voltage (at least on the dashboard voltimeter) reads the usual 14V or so when running. So, to the dealer and keep fingers crossed. Thanks.
#25 of 25 '04 Z-71 Suburban Door Locks won't unlock by tahoedrvr Oct 14, 2009 (6:54 pm)
At 120,000 miles, the second row locks won't power unlock, either from the fob or the switch on the driver's door. They do lock, from fob, switch and autolocking. Have tried all programming options, pulled 20 amp fuse labelled "LOCKS" that serves the system, disconnected battery, no change. Front doors work fine. Would pull the unlocking relay on fuse block and replace, but I can't get it out of the fuse block. Are they that hard to pull? Does same actuator/solenoid lock and unlock? Any thoughts appreciated.
