1990 4runner v6.. power windows and heater motor doesnt work..

Aren't you the guy who put a diesel I6 in your runner - surely you can figure this out!

I'd guess a wire has shorted somewhere, just do a resistance check across the window switch.

Yes i am.. so i cant ask Questions anymore?
is there a relay or something that controls the power windows and heater motor?

Power windows use a 20A ckt brkr, door locks are on a different 20A ckt brkr.
Heater fan is on a 20A fuse via the heater relay.
