Power windows stopped working?

Hi,

To get you started, I attached the wiring schematic below. Also, there is a power window relay that is involved here as well as a circuit breaker and a traditional fuse.

Since this uses a circuit breaker, the easiest thing to do is remove the relay (relay H), and check pin 30 for power.

If you look at pic 3 below, it is an enlarged pic of the relay (right side of dash relay box). Note there are 4 numbers indicated. When you remove the relay, it will have numbers on it the same as indicated in the picture. Determine which is pin 30 and using a test light, see if there is power present with the key in the run position (engine off).

If you can't identify the pin, probe one connector at a time where the relay connects. Two pins will have power and two won't. I need you to confirm that is what is happening.

Pic 4 shows the relay's position. The 5th pic below shows the radio fuse that needs to be checked as well. That powers the primary side of the relay. When you check it, make sure there is power to and from it.

One last thought. The circuit breaker for the windows is located in the fuse box under the hood on the passenger side of the vehicle. See if you can find a different one having the same part number and switch them to confirm it is good. See last pic below for location.

Let me know what you find.

See pics below.

Hi,

If the battery was faulty or weak, you should still hear some reaction from the window motor. They may run slower or just click.

If you are thinking the battery is weak, try connecting jumper cables with a different vehicle to see if that makes a difference. Even a battery charger could work.

Let me know.

If you can, let me know how things work out for you.

Take care,

Hi,

If you aren't getting power to the switch and the circuit breaker is good, there has to be an open in the wiring between the two. How deep did you dig into the wiring?

Hi,

If the power isn't at the switches, the problem is likely between the switches and the circuit breaker. Actually, it would have to be. Check the wiring between the door frame and the doors. See if one has broken. That wouldn't be uncommon.

Let me know.
