First post about my first ever Mercedes. I have only owned my 87 300E for a few weeks and just starting the learning process about these cars, so I hope to get some advice from some experienced owners.

This is a great car, and everything works except the power seats. Neither the driver, nor passenger seat will respond to seat adjuster switch inputs, following the directions in the owner's manual. No clicks or other noises indicating attempts by the seats to respond. Fuses checked and found good, but replaced with new anyway.

I would suspect switches if I could get some kind of response from either side in any direction or the memory buttons, but absolutely nothing happens.

I read about a seat memory relay box under the front driver seat. Could a problem with that cause this? Any advice about troubleshooting this would be greatly appreciated. Thanks much.
