Is there a separate fuse for the a/c compressor ?
System is charged, but the compressor is not kicking on. Fuse #7 is OK. On my 95 E320.

NO, the Klima relay gets command signal from a/c pushbutton & then looks at engine RPM.

So it's possible the pushbutton module is bad ? Heat function still works ok.

To turn the compressor on...
ON that car the pushbutton sends GROUND signal from a/c pushbutton thru the low pressure switch on drier & then to pin # 10 on the Klima relay. Is that signal getting to the Klima relay?
