As a do-it-yourselfer, I appreciate this blog for the invaluable help it provides. Although my 2004 Z71 Tahoe doesn’t have this problem yet, I know it’s coming….sooner or later. So, I’ve bookmarked this page for future use.

Thanks Grant.

QUICK FIX One can manually extend the lift gate handle cable (see finger, Chef’s picture #5 above) and snub it’s lead end into the housing of the ‘tailgate release mechanism’ (see arrow picture #5) thereby having having two leaded cable ends within the same housing. This results with the ability to open the liftgate using the outside handle because the liftgate handle cable now pulls the ‘tailgate release mechanism cables directly. I crimped the housing somewhat to ensure that both leaded cable ends stayed put. The trade offs are that I can’t lock the liftgate nor open the rear window. If the vehicle is otherwise locked and the liftgate is opened the lights blink and the alarm sounds. On the positive side, the fix is easy and zero cost. Due to the age and mileage of my 2006 Yukon, I’m not going to be in a hurry to replace the faulty mechanism (if ever). Thanks for the pictures and the insight.

The black lemon strikes again. My 06 yukon denali is a piece of junk. I have had more problems with this vehicle than all my other vehicles combined. It will be my first and last GM vehicle. After 2 transmissions, 2 oxygen sensors, 8 light bulbs, transmission oil gasket, and now the liftgate and window are locked and I can’t open them. Thank you so much for the information on your web site and to all of you who have added your insight to this problem. I will fix it myself, save a few coins, and not give another cent to GM that I don’t have to. Thanks again.

Several months ago my six CD changer in my 2006 Tahoe stopped working (with six of my fovorite CD’s stuck in it). I went online and found out that this was a common problem with the Tahoe. Because of the great expense I never got it repaired or replaced. I blame the crooks at the dealersip for that. Now the liftgate won’t unlock ! ! ! I went online again , found your post, read your remedy, squeezed my 300 pound plus butt into the back of my Tahoe, removed the panel, found the problem, fixed it. I found the design flaw, bent the tab so that it makes contact with the releasing mechanism. I think the actuator IS broken because now the liftgate won’t lock but I can open the liftgate at will by pulling the handle. Thanks ba bunch for your good deed. I owe you “a cold one” too. My cost ??? $00.00 .

Hello,
I have a 2005 Z71 Tahoe. My rear window and liftgate will not open. Could it be a fuse? (A girl can only hope). How can I open the liftgate without damaging the car? Thank you and Happy New Year.

Thanks for all the great info. Had the same problem in my ‘05 Tahoe. Removed the circular spring from the actuator and that did the trick. Motor must be weak though. Wonder how long it will last? Wish I could find the motor.
