Fuse Problem on 500SEL 1985

Hey guys!
I keep blowing the 20amp fuse no. 11. It is the Climate Control, Air Cond. Compressor, Switchover Valve and Idle Stabilization. Which one Should I check out first?

I would check the compressor clutch for too much current draw. Normal load of the clutch is 3 to 4 amps. One other note, according to my information that should be a 25amp fuse. That information is from AllData not a fuse box cover so check the list on the cover and see that it jives. I believe the blower is on that fuse too. The blower will draw as high as 16amps or more on a worn one. Mercedes has a modification on this fuse. They have a fuse relocater kit that moves the fuse outside the box and uses the 30amp strip fuse instead. You might pull up the top of the fuse holder and see if your fuse box has started to melt from all this current running through it. I've seen that a few times too. If so installing this kit is good idea. Good luck.

My parents had this problem back in 96 I rember what we had to do was convert the fuses and relays over to an american style fuse (two Actually 2 20amps) Just figured I would mention it not sure what exactly what was done but I rember it was origanally 1 10amp that kept frying
