Any help with this would be appreciated. I have an 07 Tahoe without auto liftgate. I pushed the botton to open the rear window and now it will not work. There is no noise or anything. I looked in the manual assuming that it must be a fuse but I did not find anything. I still think that that may be the problem but any assistance would be greatly welcomed.

 

Welcome to the forum.

You'll need to remove the inside panel and check for voltage at the switch and verify that the switch is working. If it is, then check for voltage at the lock actuator. Also check grounds.

 

I assume you have tried it with the remote and the button above the plate?

 

4collins,

I have the same question as ousig2408. Did you try opening it any other way?

Thank you,

I'm stumped, u have a 2010 tahoe ls 4wd ppv. The rear liftgate works fine but the wiper doesnt work and the liftgate glass wont open. Neither the button on the liftgate or the one on the fob do anything. I popped the panel off kinda cut u cant take it off without opening the glass everything looked fine. Please help.

 

did you figure out the issue I have the exact same problem with my suburban?

 

Have the same question 2007Suburban LTZ - replaced button but neither button or remote will open the window so how can you get the back cover off to check or replace the mechanism that opens the window?

 

I have found that if the wiper motor is not working properly, it won’t let the lift gate operate. Try a new wiper motor
