Both my power seats on my 2006 Crossfire Roadster are not working. Tried to change the fuses but they still don't work.
Nothing seems lose/wrong underneath the seats. Very rarely they work for a few minutes.

 

The relay which is under the dash is known to suffer from dry solder joints in many cars. You can try and run the solder properly or replace the relay.
Put ‘seat relay’ in search there is a PDF on it, it shows where the relay is located and the part number. Do not buy it from s dealer.

 

Thanks for your reply, I read the pdf, but that specific relay is very hard to come by here in the netherlands, shipping it from ebay would cost a lot, is it hard to sold it yourself because I’ve only solded a couple of things in my life so far...?

 

The car was made in Germany so I would imagine it is available over there. It does not have to be the same maker as these items are universally available and are made to the same specifications.

 

So would a multifunctional relay like this work?

 

If it matched the specifications I guess it would, you have to match the specifications.

 

Okay, I will look into it, thanks for your quick replies!

 

Here is one on eBay over here. CLICK
A bit pricy but you can read the part number on the part in the middle picture.

 

I found the relay here cheaper, fitted it and it works !
Thank you very much for your replies!

 

OK, just for the record what part number and maker was the relay you used?

 

It was the original mercedes relay with the part number you listed in your pdf

 

Great, thanks.
