ok i have a 91 chevy s10 blazer that has all the optional accessories. Im not sure if im doing this correctly, but i know you put the car in park or neutral then you can use the button to open the back glass/hatch. i know the motor for the popping mech works because i stripped a wire and used a drill battery and it popped just fine. used a test light on the switch and that worked. is there something im doing wrong? is the rear window popping mech tied in with something else, like the power locking doors? and is there a relay maybe that needs to be replaced. i dont think theres a relay but im just trying to eliminate small simple things. THANKS

 

mine wont operate unless it is in park or neutral i think its a safety feature

 

i think i also saw something that said u had to push the emergency brake in while its in park or neutral?
