AU1 Fairmont AC is cactus - blowing mostly cold air, then occasionally working such that mist is blowing from the vents!
I called an auto A/C 'expert' who tells me that it 'definitely' is the orifice valve but I am not convinced. I figure that if this valve is the issue then the piping should be cold from the compressor to the valve and hot from the valve to the firewall. The situation is however that the entire piping is hot. This suggests to me that something more serious is going on upstream (i.e. condenser) Furthermore, as I think I also have a prob with the AC clutch, when the A/C does work I get hunting at idle. Interestingly I get no such idle problems when its blowing hot air further suggesting to me that the problem is more serious. Can anyone offer any insights into this? Or correct my logic? |
