i have a chrysler 1998 voyager and i have just had the gas changed on the air conditining even though it was saying ther was gas in there but it was blowing warm air.You can here the compresser kick in when you turn it on but still blows warm air, they said there are no holes anywhere, so what could the problem be????

 

I would need to know the high and low side pressures if the compressor is on and u are only getting warm air.
