Mercedes uses those round in a bunch of applications. Can you take a pic of where it came from? Are your electric windows working?

The one closest to the fender is for the electric windows. I'll try to figure out what the other one does.

Here you go. My windows all work fine by the way. I have had a lot of trouble trying to locate one of these relays.
Thanks Guys.
John.

Wroding, if you're ok with used relays, do a general eBay search for the things. Mercedes used these same relays across all their models of like-year. I started to amass a collection of the things before I sold my car.

Thats strange? As you can see the left one is out but windows are working. As far as pn's are you asking for the numbers on the case of the relay? l will check in the morning.
Im fine with used relays as long as they are working. Do you have any for sale?
Thanks Everyone.
Cheers John

That is strange. On my 4.5 the left one does the windows. I removed it and they stopped working, plus from your picture the left plug has heavy gauge red wire which looks identical to mine.

I'd give them to you if I had any left. When I sold the car, EVERYTHING went with it...

But in watching eBay, I found single and lots that were very reasonable. New, these things will go for upwards of $100. Used, $5 to $15 (at least, such was my limit)...
