Question about 1998 Toyota Avalon
All other windows switches work fine door locks work fine master door lock switch works fine ONLY NO WINDOW use from Drivers Master switch ANY WINDOW does anyone know if/where there are relays for master switch? new switch installed, still same problem. window motor tested, works fine with jumper 12v direct driver window "USED TO" work, sometimes, but has totally quit when master switch assy removed, NO WINDOWS WORK please only comments from experienced knowledgable persons, no guesses, as I can outguess any of you with imagination please don't waste my time if you don't KNOW what you are talking about. thanks, ed
"...when master switch remove, NO WINDOWS WORK"
This is correct--your master switch is part of the total circuit for all the windows to operate. Assuming the other windows work on their "relative" switches (passenger switch works passenger window etc.), you can assume this; it is not a relay problem. You only have one relay--a bad one would affect all window switches.
First, check your ground wires! Disconnect, clean (abrasively) and reattach)
Second, use a test light (starting at the master switch terminal) to determine if and why it's not getting voltage.

Their are two fuses that power this system. One is a 15 amp gauge fuse and the other one is a 30 amp main power fuse. You can also check the power main relay, your ignition switch, or i could possibly be a fault in the wiring

if you can here relays when unlocking/locking check for power at door lock actuators inside doors, if you have power on lock/unlock and good earth from connector actuators are faulty.
if no power on test light when operating check output from central door lock module while operating, none coming out of module then it might need replacing.
check 30Amp power fuse for main relay under bonnet (which goes to pin 8 white/blue on module)and 10Amp gauge fuse in cab(pin 1 blue/red on module),pin 15 is also power when relay is on(red/blue) with test light, and module/ actuators.
check outputs from module pin 3 & 4
that go to door locks

i know on some toyotas, you do not need to remove the door panel just the handle where the switch assembly is located...if the panel around the switches is plastic then pry GENTLY up on the plastic to dislodge it from the door handle and inspect connections there...if everything checks out fine, then check fuses...perhaps this was a problem for so long that the window motor finally blew a fuse. if so replace both fuse and motor...if fuses okay, then with a long screw driver locate any screws under the door handle, bottom of the door panel, mirror panel etc, and remove...then gently pry outwards on door panel until it is released. disconnect your harness at the window motor and hook in a test light and operate the switch..if light illuminates, replace motor..if not, then replace switch or switch panel..which ever/.

Have you tried replacing the master window switch? Just because the other windows work doesnt mean that switch for that window is good.
The main switch is controled by the drivers door main unit.....i had to use a forward force on my windows switch for it to work....so replaced the whole unit, you could find those on ebay cheap if local auto parts is expensive
