w124 A/C compressor short cycles
I did some work on my a/c system on my 1987 300D turbo.
Replaced a/c hose, Klima relay, control unit & rec/drier. I recharged the system with r134. The only problem I'm having now is that the compressor keeps cycling on and off. We have the proper amount of 134 in the system, so I'm not sure if it could be the pressure switch or something else. I'd like to be sure before I evacuate the system again. And sometimes the blower fan dosen't come on until I turn off the ignition and restart the car! Any thoughts are appreciated.
