First, i have an 88 GMC jimmy sierra classic, Power windows and gate and such.. I lowered my window down (except for 4 inches, but enough to clear top.. its weak and i didn't want it stuck all the way down) And i tried pulling on the inside handle to release it. No luck. Is there a lock like there is on the doors? I couldn't find one.. Nor do i have an owners manual. So, Is there a hidden lock? Do i need the window 100% down? Is it busted? Or do i need the rear key? I don't have a key for the rear.. =/ Thanks for putting up with my stupidity! Edit - The handle opener also doesn't feel like its grabbing anything.
