1987 4runner back window problems
 

I was having problems with the rear window not wanting to go up or down so i hardwired it. After doing this the window works great other then it wont go up or down when the lights are on. Any suggestion on why this is would be great

Restore it to stock and we'll help. How can we help since do not know how you hard-wired it?

turn off your lights

RAD4runner is correct or post your schematic of what you did along with pics

+- is up
-+ is down

Lights are screwing you over.

Search forum for MY post "how rear window control works", restore your wiring to schematic I posted, do tests EXACTLY as I suggest, let us know EXACTLY, in clear manner with AS FEW WORDS as possible, what you get.
If you get sick of it, like I am, and successfully convert it to flip-up window like on camper shells, pls let us know how u did it because I want that on my truck. :)
