please help with ac issues

[Repoman]

I recently joined as a member here and this is my first post. I have found this sight very helpful on previous problems I've had but this one is stumping me. I have read dozens of posts on ac issues with the x5 and some are similar to my issue but nothing exactly like mine. I'm not a big fan of just replacing parts up until it starts working again, especially at the prices of these parts. My wallet and I would rather replace only the part that is faulty. Well, here goes.

My ac is blowing outside air temperature air only when any ac function is selected on the ac control panel. My condensor fan up front never engages. My ac compressor never engages. I do get the kickdown from the engine when the ac button is pressed but no compressor. It will always blow exterior ambient air temperature air no matter what speed I am driving, and for however long I have been driving. I would think that even if the condensor fan is not working, driving at a higher speed would simulate it working and allow the compressor to do its thing. However, even during cool nighttime cruises at higher speeds for longer periods produce no cold air. All other ac functions seem to work properly (all interior vents seem to be working fine and all blower fan functions seem to be working), just no cold air. My fuses are all fine. AC system was checked for freon and it was full, would not take a charge.

My thoughts were that it is probably the condensor fan but if that was the case, wouldn't I get some cold air on one of those cooler nighttime high speed cruises? Also possibly the FSR but all other functions that the FSR controls are working just as they are supposed to. Could be the compressor since it never comes on but at 55K miles . . . it better not be!

It was working great one day when I got out of it and 30 minutes later when I got back into it, no cold air. Has been a week now with no cold air. I've tried to be as detailed as possible but if I've left something out, let me know. Can you good people assist me in my diagnosis? I have read pretty much every post on here for ac issues and nothing seems to be exactly like my issue. Thank you in advance!
