My ac works decent (not overly cold) when it works... I turn it on and then it works for about five minutes then it gets warmer and warmer... I don't know whats wrong but if I need to recharge it where would the low pressure port be?
Thanks.

 

The pressure port is on the frame rail like right behind the passenger side headlight.

But the compressor clutch might need to be reshimmed also.

 

I'll give that a look, thanks!
