Can anyone recommend how to recharge my air conditioner in a 1996 passat. Refrigerant is r134a. Specific questions are as follows:
- what is the size of the fittings to fill the system with the refrigerant
- there are two fitting near the fire wall, which one to use, if any
- is there a sightglass to see how much is in system.
Any help would be greatly appreciated. I am trying to get out as inexpensive as possible - that is why I am doing it myself.
Thanks Greg
