1987 190E 2.3L
intermittently a/c climate system shuts off completely no blower motor or no a/c compressor.
When we turn ignition off and then back on sometimes it starts working.

When it works it might only work for a short time then it shuts off completely again

We have replace electrical contact switch, the a/c push button control unit, klima relay. check all sensors, all check out within specs. any help would be much appreciated.

thank you for your time,

scott

If the blower quits, how do you know if the rest of the system is working or not? I would check the blower motor and replace it if needed. It may be your whole problem.
