If you didn't add refrigerant to the system there is no reason to release refrigerant from the system because the low side reading is too high. The high side pressure switch is only there to disengage power to the compressor to stop it from building up too much pressure in the system.

Was the compressor running when you read the "Green" gauge? Compressor has to be running in order for the low side pressure to decrease because that is the "Suction" side.

Gotcha...no, the clutch was not engaged. The auxiliary fan wouldn't come either and I physically checked the fuses but, haven't with a meter. Will confirm they're condition with a meter this weekend. I suspect it's either the fan or compressor but, wanted to get input as to what possibly is the culprit. Its too damn hot down here to go without ac.

Thanks!

So you bled down the low side so that it match the "Green" Gauge mark without the compressor engaged. Hate to tell you but you are now low on refrigerant. The system could be so low that it won't allow the compressor to turn on.

If you have some BMW scanning software such as BMW 1.4 or Carsoft 6.5 or INPA, you can check to see if you have a fan fault or other problem with the HVAC system.

HVAC head unit...it's referring to either the IHKA or IHKR control panel...the unit in the dash that allows you to direct air flow & air temperature etc. :)
