Last week I turned my BMW AC on, it only cold on the diver side, but warn on the passenger side, I took it to BMW dealer, but they said I have to leave it there for couple days for them to check. So I went home I search online, and here how I did it. Now it works fine. Hope it helps someone have same problem with there cars AC.
So I proceeded in recharging the bimmer.
I went to Autozone and buy a kit of r134a freon (about $26), this recharge took about 15 minutes.
"- First remove the inlet caps. the big one on the left is the High side. the small one on the right is the low side. Use ONLY the low side to charge with. See what your current charge is. Start your car on and turn the ac to max. Also note your engine needs to be at normal operating temperature, over charged systems can also not cool.
- Attach your gauge to the low side and then the high side, you should be around 25-35 psi on the low side and 160 - 185 psi on the high side. mine was around 20 psi and 140 psi.
- Attach the freon can to the valve and attach to low side inlet. slowly open can and you should feel the can getting cold. this means the compressor is sucking in the freon. I added about 1 can of freon, but I am very familiar with ac systems, you should do half a can at a time and check your levels. My ac was cold at 25 psi low and 175 high at 48 degrees. it was cold enough for me. If you have to add more than 1 can of freon, you might have a leak and so you will need to check that out. time for a test drive TTYL."
