[Scourge]

Hey All,

I've been having some periodic issues with window fogging(on my '07) as the weather has been cooling down. The other night, it got really bad - even with the car at operating temp, I had to open the windows to clear the fog. While trying to clear the windows, I noticed that my A/C compressor was not cycling on when I moved the heater control into the defrost position. After a bit of Googling, one possibility I came across was that my refrigerant might be low enough to trigger the low pressure switch to disable the compressor.

Has anyone else come across an issue like this? If I am low on refrigerant, could it have just dissipated over time or is a leak a sure thing?

I did just notice the other thread discussing the air recirculation flap so I'll look into it tonight when I get home, although I don't think it would explain the A/C compressor not coming on.

Thanks!
