Adding freon to the cooling system

you don't add coolant to the compressor, you add it to the low pressure port in the line. google its location. you can buy a rechill kit at the autoparts store. the hose that comes with it will have a quick connect that will only work on the low pressure port. then follow the directions. also, check all of your fuses and relays associated with the a/c. The kit will come with a gauge that tells the pressure in your system. if the pressure is correct, you may have something else wrong.
