A/C refills?

If your system is low on refrigerant, the compressor won't kick on anyway. The system monitors pressure and refrigerant level, when it gets too low, it just disables the system to run. If you ran the compressor without the proper level of refrigerant in the system, you'd ruin it.

Buy at least three cans of refrigerant and one of "refrigerant/system sealer." You probably have a slow leak in your air/con sysgtem, is why it doesn't work. Get an install set of gages and valves, read the directions, and have at it. Here's a tip. Your engine can get quite hot during this period when running. Get the biggest fan you have in the house and put in front of your radiator. Hell, put ALL your fans in front of your radiator, and keep an eye on your engine temp gage.

Hey, the radiator wouldn't get so hot if you filled it with fluid!

Oh yes it will. Been there done that. Go to a garage and watch them work on air/con. They have a huge squirrel cage fan that moves massive air they put in front of the radiator.
