GMC Repair: A/C 99 Jimmy, guages, norm


Question
A/C cycles condersor for only a few sec's then cuts off and back on.  Replaced condersor and rec./drier/orifice tube. Tried to charge system from low side presure reads full/overcharged but didn't even put full bottle of 134 in.  This the norm or something I'm missing?

Answer
What you need to do is put a real set of guages on it, the only way to properly diagnose an A/C system is to know the actual low and high side pressures. If you can get that information I should be able to help you.

I am sorry that it took so long to reply, it has been very busy around here.
