Power window not working?

Hi stevepti,

Expect to see a broken regulator top end roller for the cable.

The inner handle is slotted in before being tightened with the screw. Push the opener forward before lifting it out slightly to enable you to detach the lever behind it.

Have you checked the fuses underhood?

Here are the schematic of the system.

Check the power window relay. Use a test lamp to test the power window fuses for battery voltage.

Hi and thanks for using 2CarPros.

It sounds like the gears on the regulator have stripped. Take a look at picture 1. You will see a set of gears. You need to remove the door panel and inspect those to see if that is what has been damaged. Also, one the panel is removed, if you crank the window up and assist the glass upward with the other hand, at least you can close it until you repair it.

The directions I have for removing the door panel are for either manual windows or electric. If there are electrical components in the directions that you do not have, ignore them.

__________________________
Starting with picture 2, the remaining pics correlate with these directions.

Disassembly
Sedan/Wagon Front/Coupe:

1. If applicable, remove the regulator handle by pulling the clip out with a wire hook.

2. Remove the mounting screw, then pull the inside door handle out half-way and disconnect the latch rod and power door lock connector.

NOTE: Remove the panel with a little bending as possible to avoid creasing or breaking it.

3. Remove the power door mirror switch and disconnect the connector.

4. Remove the screws and clips (see trim pad remover) attaching the door panel. Remove the door panel by pulling it upward and disconnect the power window and courtesy light harnesses.

I based this diagnosis on the windows being manual and not power because you said when you roll them up. Let me know if this helps, if you have other questions, or need additional information.

Take care,

Hi Anjan,

If operating the switch causes noises to be emitted from the window as if the motor is working, you have a bad door glass regulator and you would have to remove the door panel and door glass to replace the window regulator.

Hi Tatiousmami,

1988 model should be cable driven so you should check if the cable is broken. If it is sensor driven, then the speed sensor is faulty. Get it replaced.

Each window has a separate fuse but the wiper fuse also controls the power window relay so not surprising if they don't work, the relay is not being activated.

Shorting should not be from the power window so you should check the wiper.

Intermittent failures are difficult to detect. Put in new fuse and try component by component till it pops, then you go about checking that circuit.

Hi Tatiousmami,

Disconnect the wiper motor wire connector and see if the shorting still occurs. If it does not, then the wiper is faulty.

I would put off the inside door panel and watch the mechanism to see if a component has broken. Pretty pricey but necessary.
