Have 1994 4runner and the power windows have quit working, have replaced 30amp fuse, door control relay and driver side door control switches. Im at a loss now and need help please.
Stop throwing parts, money and time at a problem unless you're absolutely sure parts are bad- or due for replacement- i.e., wear items
Like MacGyver1979 said ^^, but digital multi-meter is better- because you could use it to check for shorts (using resistance setting) with power off- even safer.
Find schematic and methodically check everything
Inspect your wiring for opens which will prevent power from getting to where it should go, AND shorts which would blow the fuse.
