I'm having issues with my power seats in the car. Neither work. The passenger's side didn't work when I purchased the car used, and the driver's side went out last week. I'm trying to solve the issue myself but am in need of a wiring diagram to better understand the power supply to the seats.
Thank you.

Hi,

I attached the schematics below. The schematics are broken down for driver and passenger. I cut each pic in half to make them readable, so pics 1 and 2 are the driver's side. Pics 3 and 4 are for the passenger side.

Here are a couple of links you may find helpful:

Let me know what you find or if I can help in any way.

Take care,

Joe

Thanks for the info, Joe. I suspect this will help quite a bit. I'll get back to it over the next few days and let you know how it goes.

(I've checked and replaced the fuse in the driver's side cabin (it was bad), but regrettably it didn't fix the issues).

Hi,

If the fuse was bad, also make sure to confirm there is power to and from it.

Let me know what you find.

Take care,

Joe
