View Full Version : A/C Problem !

07-31-2007, 07:54 AM
I have a 96 a4 and It doesn't have a low side port to recharge the system. It has a high side port on the front of the radiator and the only place I can see to access the system from the low side is at the low pressure switch by the firewall. I took the switch off and the r134 nipple will not seat correctly. Is there another location to charge the system or is there an adapter to fit over the threads ofwhere the low pressure switch is?
