Having a weird ac issue, that I don't even know where to start diagnosis. Sometimes pushing the ac button I don't get cold air, but if you then shut off the car and restart it, the AC will come on. It's really intermittent with this happening, but has been happening more and more lately. Once it comes on, it will stay on, though. No, I have not checked the pressures yet (I know, I know). Yes, I know it's November, but I am using the ac to defog the windows at this point. I haven't looked at anything yet, but just wanted to get an idea of where to start looking. Two summers ago had the compressor, drier, expansion vavle changed out, and this past summer had to replace a hose from compressor to the drier due to crack at one of the fittings.
