2002 cavalier LS 2.2L automatic
the air conditioner is not working. i have taken the cover off the relay and manually closed it which causes the compressor to kick on and ice cold air to blow. i have swapped relays but the same issue occurs.

 

is the refrigerant level low?

 

I believe levels are good, I will double check it this evening

 

How can you know the pressures are good unless you test them?

 

Yes i agree. That is how we found out it was not working, I personally didn't check them because I don't know how but a family member who does minor service and has the equipment is the one who said everything was reading correctly.

 

best bet if you have access to a machine is to recover the system...they you know with 100% accuracy the charge level....looking at pressures on a guage isn't the best method

 

I will definitely keep that in mind when I get a chance to mess with it again
