Hello everyone,
I have been struggling with this for a few months now and mechanics can't figure it out so i thought I would ask the gurus here.

2000 S500 with rear a/c.
new ac compressor and freon filled correctly by indie.

problem: when the car starts in the morning, the ac works perfectly. however once the car is turned off and turned on again within 5 minutes, ac simply doesnt work. no matter what the settings.

if I let the car sit for an hour and start again, ac works perfectly again with cold air as it should.

Had the ac pressure checked, when ac is working normal, the low port and hight port readings are perfect, shut down and restart car, no ac, and the pressure at lo port is really high.

any help / advice will be appreciated.
I already checked the codes from the ac panel inside the car through the secret menu and there aren't any codes, i did however reset the acc control unit numerous times.

thanks again in advance
