I am also looking for a 2003 Toyota Camry or newer.

Where is the low-pressure AC port on a 2003 Toyota Camry?

• My 2003 Camry's air conditioning has not been running at peak performance, taking much longer to to cool the car. So I bought R- 134 refrigerant can that includes leak sealer and oil, and has a hose attached that measures PSI to put in the proper amount of refrigerant. But the directions say to connect the can hose to the low-pressure port on the AC system. Where is the low-pressure port on a 2003 Toyota Camry?

• Answer:

  I would advise caution here for several reasons, the low side must be charged with vapor with the can upright. Liquid refrigerant charged into the low side will damage the compressor as liquid will not compress. 2003 Camry had a couple other issues not related to the charge amount. They had intermittent problems with the ac clutch relay kicking off, causing the car not to cool.(usually but not always, the indicator light on the switch would flash.)There was an updated relay to fix this. In high humidity areas of the south-sometimes the evaporator can freeze up and block the cool air--there was a sub-harness wire that can be added to prevent this. your car really should be diagnosed with a full set of gauges to determine what the state of charge is. If you overcharge it, it will not cool as well. U can see it is something that really is wise to go to an ac shop or preferably a dealer as they have access to this information. If after all this you still want to try, the low side is the fatter line coming out of the firewall on the passenger side. The low side fitting is approx 6" from the firewall--good luck. ... T&T
