Please disregard all the post above. I deleted it quickly when I realized that it was only relevant to W209 CLK models.""You say that you have checked fuse f20 (10A). This protects the rear screen blind relay (K74) and motor (M24). To access the motor you will have to remove:
1. paneling on the C pillar. 2. rear shelf.
I cannot locate relay K74, (it is not with all the other relays) but I suspect it is in the trunk, behind the removable covers on either the left or right side."
Yes this fusebox is in the engine bay. The fuses are in 3 Blocks.I only check the fuse that's in the engine bay. There a small fuse box in the truck (next to battery) with 9 slost and a relay next to the box. I just don't know which is which.
I'm trying to locate that fuse or/and relay.Ok, Junster, you're obviously not any kind of mechanic. Exactly what part of that sunshade would require a fuse other than the motor?
Just my opinion but it's not wise grasshopper to dig into your very high tech Mercedes if you don't know anything at all about basic mechanics and electrical stuff. A motor with a fuse is about as basic as it gets.
As I wrote above, there is no sun blind relay on W208.I'm trying to locate that fuse or/and relay.
