I have a W124 (200E) that is an excellent workhorse except for one peculiarity. The air-conditioning system will work beautifully so long as I use the car everyday.
If I should miss starting the engine and therefore miss switching on the air compressor or I leave the car unattended in the driveway for a day or two, then it becomes next to impossible to get the air compressor to "cut in" for the air-conditioning system to function.
I would then have to drive the car for a couple of days (under a hot sun most of the time) before ?.. presto ?.. the air compressor suddenly "cuts in" and the air-conditioning system is back running normal again!
Could anyone help, please?
