Hi, I have a 1986 190D 2.5 non turbo.

My rear window defroster is not working, it does not turn on so I will be checking to see if it is getting any power.

I located the 16 amp fuse in the fuse box and replaced it.
I see online that the rear defroster uses a 30 amp metal strip fuse as well.
Is there also a relay?

If there is a relay and a metal strip fuse for the rear window defroster, does anyone know their location?

Thanks.
