Recently my air conditioning stopped working; either it would quit after
five minutes, or it wouldn't come on at all. The light on the switch
turns on, but the compressor doesn't engage. I'm also noticing that the
engine is running a little hot and both fans are running (normally only
one fan runs unless the air is on). The radiator is full and not
leaking. Any ideas about what's wrong will be appreciated :-)
First thing I'd check is to see if the system has refrigerant. There
is a pressure switch that prevents the compressor from running if the
charge is low.
To check is a simple thing to do if you have the proper gauges and
know how to attach them. In the US, you have to be licensed to work
on refrigeration. You may want to take it to a shop that does that
sort of work.
You do not indicate the age of the car, but after five years, this is
a fairly common problem with auto AC. They are subject to a lot of
bouncing around compared to your home units.

it sounded like the two issues were related (air not working and engine
No, not a dealership. It turned out the thermostat was stuck in the
closed position which caused the overheating. Now that there's a new,
working thermostat the AC is back to normal. Thanks to everyone who
