How to Fix a Slow 1995 Toyota Celica Power Window
If you're having problems with the power window of your 1995 Toyota Celica, there are several areas to check. The power motor, used to operate the window glass, could be worn out, or there could also be moisture or debris in the switches or electrical connections in the system. Locating and correcting the problem will take the average backyard mechanic about 30 minutes to diagnose and repair.

Checking for moisture
Remove and check the switch assembly for moisture by prying up one corner of the assembly with a screwdriver and pulling the assembly out by hand. The wiring harness is attached to the rear of the assembly, and the adapter plug can be pulled apart, releasing the switches from the door panel.
Make a note of how tight these plugs are, as loose plugs with intermittent connections can cause a slow or jerky window.
Replace the switches if the exposed rear terminals are tarnished or green; if they aren't a shiny copper color, moisture is evident.
Replacing the power motor window
Replace the power window motor by removing the door panel, which is held in with arm rest bolts, door handle screws, and plastic pop rivets. Turning the bolts and screws will release them, and tugging at the individual pop rivets will disengage them. Start at the corner of the door panel and pull the rivet loose, then work your way around the panel. Some of the rivets may break from age, and it is common to replace several of them when taking the panel off. Set the panel aside.
Unplug the motor from the wiring harness and remove the mount bolts that hold it to the window regulator. Pull the motor directly away from the gears and replace it with a new unit in the reverse order.
Pop the door-panel pop rivets back into place with firm taps at each rivet after placing the panel onto the door metal. Replace the switches and test the motor.
Checking the wiring
Check the wiring from the fuse panel to the window switch assembly by testing it with the circuit tester. Apply one side of the tester at the fuse terminal for the window, and the other side at the switch.
Press the switch and check the tester. A weak or intermittent light on the tester could indicate a short or moisture in the wires, and will require professional repair as this moisture has no doubt made its way to other parts of the electrical system.
Find a professional repairman if you might have moisture in the electrical system.
