1980 500sel

[michael Manning]

Just bought a a 1980 SEL ....seems to be in good shape. I have mostly owned and have performed minor repairs on Volvo, so this is my 1st MB experience. I have a few concerns..hoping I could get some help.

The Idle doesn't seem to want to kick-down. Adjustment screw, or something else like a sensor or relay ???

Secondly...the Climate controll seems to be getting power and when I turn the dial I hear a clicking ( relay) sound, but no blower no AC compressor activity..no NOTHING!

Lastly it's a 80' 500SEL. I can't find a lot of info on the car, carfax on the VIN starts in 1995. The local body shop told me they didn't even show an 500SEL for 1980 on their database. Was the 80' 500 SEL made for Europe only or made for distribution other than in the US?

Any help is appreciated....
