Question about 1996 Toyota Corolla

1 Answer

The electric windows don't work, but only intermittently: some days they work great, some days they fail. They work 90% of the time. The shop is telling me I need new, very expensive motors. Is that really likely to be so? Or is it more likely to be the switches; or the connection to the motor? How can I take the window controls apart to test them?

    ok, thx.

    I accepted the answer, but then I thought of another thing:

    Sometimes the passenger-side window control works, and sometimes it doesn't. When it doesn't, I can raise and lower the window with the driver-side control. That makes me think that, perhaps in addition to a malfunctioning motor, there's a connectivity problem.

    I'd like to prove that out. I certainly agree that I don't want to be taking motors apart and cleaning off commutators and replacing brushes. But I'd like to be sure it's not an intermittent connection issue.

    So: How do I get the switch and motor in a place where they are accessible? Thanks.

It is likely the motor itself.
The brushes leave a coating on the commutator after years of use that can be cleaned with an eraser.
It requires removal and disassembly to clean.

Unfortunately - that quick fix does not last long - unless you replace the brushes.

You will find it easier to just replace the motor that is acting up.

Thanks for using FixYa - please accept this answer to remove it from the work queue.

I have a fiate punto grande and the offside electric window keeps failing had at garage three times now but still keeps failing


Would I be correct if I said.....when you operate the switch to get the window to lower it will do it and then may stop? or is it when the window has lowered that it has trouble closing? Has the switch been replaced? what wires are being soldered? Is there a bad earth connection to the motor? Unfortunately Fixya does not provide an accompanying video option.

Engine cranks over normal, but won't start?


Intermittent faults can be hard to diagnose. Tests must be run when it is failing, such as is there spark at plugs? Is fuel pressure correct? Think of electrical parts such as fuel pump relay, ignition switch, crank/cam sensor. Does it fail more when cold or hot weather? Wet weather?

Will not start then the next day it starts


Crank sensor is common problem on these. They are interminate and usually cut out when hot and will restart after they cool off. Connectors and even oil in the connections from leaks.

2000 Chevrolet Impala LS 3.8L keeps dying while driving, no codes or warnings. It's been happening for years but seems worse now. Ignition module already replaced. Fuel pump hums when I turn ke


many possible causes. sounds all too much like a crank sensor failing. when it dies, does it act like you shut key off, (instant stall)? or does it sputter and cough, then stall out? seen this same situation and problem many times in my shop and a cranksensor fail can be hard to catch when it fails. most likely cause.

2004 chrysler pacific will start sometimes but sometimes won't


I would suspect the fuel pump is the problem, it may be sticking at times and this causes a no start. The pump is located inside the fuel tank and it is electric.

When the outside temperature has been above 90 degrees, and with the air running, my 1995 econoline 150 conversion van, 5.0 engine, has stalled out. on the first instance, i put the van in neutral and...


I chased a similar problem for several years. Stalled, got towed no problem found. The thing would heal and then fail at random on hot days. After checking everything electrical, fuel pump pressure etc, nothing could be found and I could not duplicate the problem. One day after being towed to a shop again, van started and would not fail but this time I had the mechanic put a clear by pass line along with a pressure gauge and I monitored the flow for about forty five minutes. Suddenly I started to see a stream of air bubbles and the pressure began to drop until the engine shut off. It was the FUEL PUMP all along and no one was able to determine that w/ all the test equipment. Went to Kragen Auto, now Oriely's and got a fuel pump. Had the shop drop the tank and install it. Have never had a problem again. Don't worry about what the mechanics tell you that it is not. Change the fuel pump

Window auto up down


So the shop doesnt know whats wrong, but says its not related to the accident. They dont know squat. Contact your Insurance company and explain what is wrong.All these problems happened after the accident. Insist that they have the DEALER check it out and repair it. They are obligated to repair the car like it was before the accident.. Sounds like a ground issue.
