I have a 1995 ford f-250 super with a 7.3 litre diesel engine.
the ac has" nt 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 ez charge with the gauges.
followed the steps by putting the hose on the low side and filled it untill the gauge showed me when to stop. Its holding fine at that position so there is no leak but the ac 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.
