Can a passenger side Window Motor get burned out by a faulty Master Window Switch?

Question

First,off, I have a Toyota Corolla 98.
My passenger side window stopped working. I took it to the shop and got the "burned out" motor replaced and they said I also needed to buy a new "master switch" from a dealer. They said something about there was too much current or electricity going to the passenger side motor (they ran it through many electric tests).

Is this possible or is it BS? I haven't bought the switch yet, I'm still looking online ($241 @ dealer, $181 so far on various sites)

By the way the shop is independent, not a toyota parts dealer.

If a fuse is bad, wouldn't that affect the whole master switch module? The rest of the windows work fine. Or is there a fuse for every door or so?

Answer 1

Switches and moters become worn or dirty. Connections become corroded and/or vibrate 'loose'.

Moisture can enter these parts or the motor causung bad thingys.

HOWEVER usually both DO NOT fail at the same time(unless vehicle from flood).

Did the passenger side motor work with the passenger side switch? Does the motor work after replacement by dealer?

Thereotically as the switch 'goes bad' voltage drops and current
increases... BUT sounds like BS to me as well.

Usually all are fused at single location. If motor replaced and still not working then you were definitely ripped off as any qualified tech can check switch- motor- fuse before charging for replacement(but there is a labor fee involved to do that! (1/2 hour $25-$50)).

Usually loose wire, then worn out switch, and occasionally bad motor. If motor working then the 'master' switch should fail shortly... but sounds like BS as the 'test' they performed was most likely a resistance test... and the switches go from good to bad awfully fast!

Anxious to know the rest of the story... like if motor when replaced worked or if car from flood(yes there are ways to tell)!

Say you're not from Louisiana or buy that car recently from around there for a 'good' deal?

Good luck, bon chance!

Answer 2

The simple answer is NO. The motor is in back of the switch. BUT, that means it could well be the other way around. A bad motor (shorted windings causing excessive current draw) could well burn up the switch. I would get a second opinion from a well recommended garage (NOT A Toyota dealer) and see what they have to say. Junk yards are full of them too (due to so many on the road, not that they are a bad car by any means) so you may even find a good used one.

Answer 3

i would go to a pull your own part and pay the most $25.00 put in your self iv'e never heard of what you say you only have but 12 volts in the cars circuitry it take 12 volts to run a window motor by the way your motor was not burned up neither all you had to do was clean the armerture where the brushes are located!!!! I fix that all the time for free just to help people out..

Answer 4

THOSE SWITCHES AND MOTORS ARE SUPPOSED TO BE REGULATED BEFORE THEY ARE PUT INTO ANY VEHICLE BY THE STANDARDS OF THE MANUFACTURER. IN MY OPINION THE DEALER IS FULL OF BS AND BEFORE BUYING FROM THE DEALER YOU TRY A JUNK OR SALVAGE YARD. THOSE SWITCHES AND MOTORS NORMALLY DON'T GO OUT UNLESS IT WAS UNDER WATER OR HIT FROM THAT DOOR IN A WRECK.

THE DEALER AND THE PARTS GUYS OF THE DEALER ARE PAID ON COMMISION AND WILL SAY ANYTHING TO MAKE A SELL.

Answer 5

Someone is shooting you a line of doo-doo!

The lift motor is a 12 volt dc motor. It operates on battery voltage, which is of course 12 volts. It can't get "too much current or electricity" it would blow a fuse if it did.

Find a shop that knows what they are doing!

Answer 6

This is possible, however, check to see if your fuse was blown. The fuse should have stopped the extra current from damaging other components, such as your passenger window.

Answer 7

Its possible... I would try taking it to another mechanic and asking him the same question.

Answer 8

yes its possible but get a second oppinon if ur not sure
