1990 300E a/c keeps blowing fuse #7?

[Benz Mondi]

I keep blowing #7 (controls a/c, climate control, back-up lights, etc.)

My a/c has always blown very cold if I wanted it to and has never let me down until now.

Via a process of elimination, if I keep the a/c clutch plug disconnected, my climate control blower works and I don't blow the fuse.

What is happening with the clutch?

Can "just the clutch" be replaced while keeping the compressor connected, like I've done with my Jeep and Chrylser cars?

Thanks.
