No AC after coolant work

[Nanniepoo]

Fired up my X5 after being down for 2 weeks. Replaced the WP/t-stat, a number of hoses and both belts. Unfortunately I now have no AC. I have plenty of airflow, it's just not cold at all. In fact it's colder if I turn off the AC. It was 71 on the test drive yesterday, and tested AC at 68 (normal set-point) and max AC, both reacted the same.

My first guess, since it's the only thing I touched related to the AC, would be the belt. I torqued the belt as much as I could with the N62's god awful set-up and believe it's fine as there's no squealing or any weird noises, so I think that's fine.

Engine does react to me pressing AC button, so something is happening. I'll be hooking up my gauges, hopefully today so see what's going on. Just a bit frustrated that I went from glorious AC two weeks ago, and then after two weeks, nothing.

I'm gonna go out on a limb and say I'm low on refrigerant.

I’d say so. Hopefully something didn’t get knocked during the cooling system repair causing a leak. It’s odd that it went from working to not working.

Dude, you have really been fuking this car up lately.
You start new thread every other week, "My Car is Broken"

You need to stop with your amateur BS and your Harbor Freight tools ,
and take this car to an actual Mechanic. (not you who just plays one on the internet).

This is an expensive piece of vehicle, you need to stop your "hope and pray" repairs before you really mess this vehicle up ... beyond professional repair

Just sayin' .... before it's too late

Which is what I consider odd as well but I don't see what I could've hit and why I was so confused. Oh well.

I disagree. The only way you learn is to get your hands dirty and try. That involves breaking things sometimes.

I think back when I replaced my brakes/rotors and rear shocks on my E36 when I was 17/18. I had no idea what I was doing, nor had the right tools. Now there is very little work I would not do myself.

There is no way I would be able to afford this car if I always had to take it to a mechanic and trust what they say.

Keep at it.

The only thing I dont do is AC/Freon- I dont have an evac machine.

You should spend the $90 and have someone evac that, test for leaks- then fill with the proper amount of freon BY WEIGHT. Add dye. See how it goes. Maybe add $50-75 for the freon you will need.

FWIW the tolerance on the fill is like 1.65lbs +/- 0.02lbs

If A/C belt is tensioned properly and turning smoothly, next thing I'd suspect is a refrigerant loss. A quick YouTube review of normal low/high side readings suggest yours is low on both counts, but I don't know the spec for our vehicles.

Almost all A/C work I take to a shop.

You sound like a typical So Cal BMW owner. Last one I was chatting with was complaining about buying new tires because you have to buy special ones that are sold at BMW and they are expensive.
