My toyota corolla 94 window driver side can not scroll up&down

Under hood, driver side, rear engine area, passenger side of master cylinder, mounted in fuel line ,

This sounds like the master switch on the driver's side door is the problem.

Remove the master cylinder & take out the
piston & clean inside

Replace all rubber flex hoses & any calipers & wheel
cylinders over 8 years old

Flush System

you should open the door panel and check if the rolling motor is trying to roll at all, if it is then the teeth for rolling up is weak else then check the fuse for the motor

you might just need a new switch try swapping the off of the other sides door to see if it will go up if it does it the old switch was bad if not it might be the regulator

Your car is still under warenty from toyota.
they will be more then happy to fix this problem for you.
i would know i work there.

If you're in front of the car. look to the right side in the back by the brake fluid resevoir. just to the left of the master cylinder.then look down. It's bolted to the firewall. If it's not causing problems, don't mess with it. It's a pain in the ****. It's rated to go 250,000 miles. I just replaced mine and didn't need to. augh!

First of all this car does not use Freon. It uses R-134a refrigerant.

Recharge through the a/c low side port, on the passenger side just in front of the firewall.

Sounds like it could be your switch going out. Does the rear switch give you the same problem? If not, then I would suggest you go to a junk yard and find one to replace the front one, even then they range in price from $35-60. A new one from the dealer is best but more costly. Good luck hope it helps.

Look to see if the window lockout button on the driver side door window master switch panel is depressed. If so, the other 3 windows do not operate. this is one of their child-proof thingys.
