Where do I connect the hose to recharge the AC?
The users manual only shows a picture of the switches in the car to operate the AC/heating system and the R134a can only says to unscrew the cap located on the metal rod, connect hose, shake can, etc. But there are seemingly 2 places I could hook up the hose to inject the recharge. There are 2 identical caps on metal hoses; which one is it? One is a little lower and closer to the engine and has a smaller mouth and the other would be closer to me and has a larger opening. Which should I connect the hose to in order to fill with the R134a coolant?
