Hey guys,
I just bought my 03 tracker back in December so this month is the first time I actually got around to looking at the AC....turns out that there's a problem...lucky me. It might be as simple as no freon in the system but I figured I'd ask you all and see if I can get pointed in the right direction for diagnosis. AC systems are one of the things that I don't have too much experience with on vehicles in general and I'd like to change that by fixing this problem myself...
Anyways, the little green light comes on as it should when the AC button is pressed...I hooked up a can of r134 with a gauge on it to the low side port and the gauge shot up to around 100-130 psi if i recall correctly. This is obviously way too high....the compressor is not cycling at all so I know that this high pressure reading is probably not accurate. I tried to put some freon in the system to see if that would get the compressor to come on, but it felt as if nothing was coming out of the can....
My question: Is there anything in particular that causes the low pressure side of the AC to give a high pressure reading? Or does my compressor not cycling mean that this reading is meaningless? Any good threads on this (I did some searching) or good places to start?
