I have a 1990 4runner and my back window has been having some problems. It will go down every time but ill have to turn the key in the back about 50 times before it finally goes up. It'll do the same thing using the button inside. Once it starts going up it doesnt stop and runs smooth. Anyone know whats wrong? I dont know if its bad wiring or a relay?

Do you hear the relays clicking when you hit the switch and nothing happens? If so, relay contacts may be dirty, otherwise, may be switch contacts or wiring.
