I have a 1995 ford F-250 super with a 7.3 liter diesel engine. The A/C has not worked since I got it. So I thought it might be a matter of just charging it. So I went to Kragens auto store and bought the r-134 easy charge with the gauges. Followed the steps by putting the hose on the low side and filled it until the gauge showed me when to stop. It is holding fine at that position so there is no leak, but the A/C is still not working.
How can I check the compressor to see if it is working? Or have you any ideas as to what is wrong?
Yes I have a test light. I had power at the purple wire so I crossed the purple wire and the other wire like you said and I could see the compressor kicking in. I cannot tell if the A/C is cold or not cause it is actually cold where I am today, but this definitely made a difference. As soon as I put these wires into there proper place again the compressor would click back out again and stop.
Before I jumped the two wires the gauge read 25psi. When I jumped them it went straight to zero. I filled the system up to 35 psi and I re-connected these wires in there proper place and I notice now that the compressor is cutting in and out every couple of seconds. :) I checked the gauge again and ts holding steady at 35 psi. I live in San Francisco city and today is windy and cold so I cannot tell if it is blowing cold or not because when I switch to vent it seems the same.
Did that but compressor is still cutting on and off and can of Freon is nearly empty. When it cuts off it reads about 35 psi and when its comes back on it drops to zero. Also, I noticed water dripping out from under it. Maybe there is a leak in it after all?
What does this mean?
Thanks a lot
