Post Electric Seat Repair

Electric Seat Repair:

One of the functions of my drivers seat was not working and was getting to me so I set about to find out why and fix it.

I needed to remove the seat bottom to gain access to the motors - easier said than done! To remove the seat bottom, four bolts two on each side need to be removed. The two on the rear sides require the seat to be moved fwd/bkw until a hole in the frame lines up with the bolts - thankfully that feature worked! Although to get at the ones closest to the centre of the car required the seat be unbolted and tilted to gain access. Be careful of the wire cable and the wiring loom when moving the while seat around!

Here is a picture of my drivers seat with seat bottom removed:



The front of the seat bottom raises and lowers but the rear does not. So I took a look at the motor:





The motor was working however a gear had broken into three parts inside the box:



Now i know what is wrong, I can try and find a replacement gear and get the seat working.

If anyone has this part I would love to hear from you!

Hello, I had a broken PLASTIC gear on my drivers seat that would not allow the seat to stay in the highest position.
I had the dealer remove the seat and try to repair, my gear was NOT a piece that you can buy as a part and replace.
I purchased 2 used front seats, had the dealer remove the piece from the old seat that I needed and fix my seat. WORKS GREAT!
In your picture you show 4 round motors where your gear is broken, I have 8 of those motors, are they all the same for each function? If they are, I will remove 1 motor and send it to you so you can replace the gear or just install the motor I send you.
Let me know if you want it, I will be glad to send it to you.
