Does power window motor or regulator cause this issue?

Thanks for your participation for earlier threads.

My 1999 Camry power window acts weirdly. I am able to bring down the window quickly, but I find difficult to bring it up.

It moves little by little. It moves little. If I press the PW button , it will not respond. I need to wait for awhile to move up little. The mechanic suggest to change the PW motor and another mechanic suggest to change PW regulator + motor together.

If Motor cause this issue, why did it come down quickly and going up little by little?

Is the problem occurring due to PW motor , regulator or something else?

Did anyone of this forum face such issues on Toyota?

What was your solution worked for you?

Thanks for sharing.

Before you go through all of the time and hassle of swapping motors and regulators, try just replacing the switch.

I recently broke my 94 Corolla's power window switch, so I grabbed a junkyard replacement. The window would go down fine but it was going up slowly and in little jumps if it was going up at all.

I swapped in another switch-bank I had pulled and the window is functioning perfectly again.

When I did it I unplugged the motor from the harness and manually powered it and it worked just as bad. That's how I tested it. The new one has worked perfectly ever since. There cars have crappy window motors from the factory.

I'm all for bench testing components when possible, but few people have access to a suitable 12v power supply or the skills to test something without it being installed.

The switch bank can be swapped without even unscrewing anything most of the time. Flee-bay sells new replacements for about $20. My local LKQ junkyard charges $19.99 for the master power switch bank.

Worst case, if it's not the switch, bring it back to the junkyard and apply it towards a replacement regulator or motor.

Also, I'm a huge fan of eliminating the easy variables before going after the harder ones. :)

This issue with Passenger side front window. If it is an issue with switch, it should work with one of the switch (1- One at driver door, 2-One at Passenger front door). In my case I have the same issue with both switches.

Do you suggest, both switches need replacement?
Wow, nope, odds on both switches failing are slim.

And I totally get it, most of us have a battery in the car, but I still maintain that few people can pull a part out of their car and correctly attach it to the car battery to test if it's working.

More power to you, zzyzzx, as you seem capable, but I have no real idea how to pull my power window motor out of the door and hook it up to the battery directly. I'd be really surprised if more than a handful of people here can too.
