I have been reading your tech forum as a guest and I can not believe how much knowledge you all have here. The wealth of information is astounding. So, I decided to join and hopefully bother you all with my problem

)

I am in the process of bringing back an ’85 190E and have been mostly working on it on weekends due to work schedule. The car has 88k original miles and was parked for many years. It is now back on the road and runs ok. I am still going to replace the lower control arm, tie-rod & drag link, Idler arm (kit), etc. I bought them already; just need time to install them.

The main issue now is with both drive side windows not working after car has been running for a few minutes. It turns out that the reason is because of blown fuse #7. I could replace fuse 7 and both windows will start working. I can drive to the corner store, park and go in. By the time I get back out and drive the car, I’ll notice that the driver side windows have stopped working again. Yes, fuse #7 is blown again. Also, there is a 4 inches long wire that has a fuse in the middle and one end of the wire is attached to fuse #1 and the other end is attached to fuse #8. If I remove this wire, non of the windows will work. The glass 20amp fuse in the middle of this jumper wire was the one that blew every time. I did the jump with a wire that has no fuse and now the #7 fuse is the one that blows, leaving both windows on passenger side to continue operating.

I have no idea of what could be causing this fuse 7 to blow every time and not sure where to begin looking. I have tools and do all my own work on my cars but my knowledge of electrical troubleshooting is limited. Please help me get past this point and hopefully get to where this car is driven daily. Car is an ’85 AMG and looks exactly like this (same color and kit) but with factory fogs http://store.classicgarage.com/me190ewchpab.html

Benz repair shop owner looked at this car it last month and after looking the engine over mentioned that “this is Euro spec car”. Please help me. I have a multi-meter also.
