Somewhere in the coolant line from the condenser, front of car, to the evaporator, in the air box. I have a 2000 sunfire, so there is a line nut right at the evap inlet, very easy to to, I'm not sure exactly how they were set up in 92', that would have been an r-12 sytem. Still it would be along the high-pressure liquid line flowing from the condenser to the evaporator, it bassically drops the pressure of the coolant to make it colder thus cooling your interior. hope this helps

I had the same problem with my 92 sunbird. after a long time of fooling around, we finally figured out it was the ignition module, it the part that is responsible for firing the spark plugs, mine was only running 2 of the four cylinders.
