AC not turning on in '74 240D
In my '74 240d, I (I = experienced MB diesel guy) just replaced the guts of my AC system. Brand new ACcompressor, AC clutch, AC expansion valve, AC drier/accummulator, and new refringerant.
Once all the above parts were replace, mechanic tried to turn on the AC inside the car, but AC wouldn't start. The green light didn't go on.
Any idea what could be wrong, or what would be the recommended way to diagnose this issue?
