Re: '93 90 A/C problems

I'm sure it's not a slipping belt, and the ISV is just a little slow to
react.

Everyone keeps saying that is' low refrigerant, but the CC head will cut
the compressor off if the charge is low, or at least register an error
code--no such codes.  I'm wondering if maybe they didn't put in enough
oil last time they evacuated/recharged the system.

Which brings up another question: if they evacuate the system, can they
accurately measure how much oil was in the system?

Thanks
