If you have the 3400 look at the firewall, just to the right of center about two inches down for the low side, and right next to the air box for high side.

If you have the 3800 the two should be together on the left side of the engine compartment.

Hope that helps.

If you look at your compressor you'll have two lines coming off it one is bigger than the other that is the low pressure side. Follow it and you'll find the port, could have a blue cap or black but if you follow it from the compressor you'll find the port

    Do you have the gauge and freon kit from auto parts? If so the connector will fit on the low side. if it dont fit your not on the low side. remember the low side is the bigger of the two.

Where are the ac recharge ports for a 2005 pontiac grand prix


The high side is located in the engine compartment, passenger side aginst the firewall. The low side is trickier. it is located on the passenger side of the engine compartment in the front by the headlamps. Easiest way to get to it is to have a lift handy. If lift not available be ready to contort your arm up behind the headlamps.

Air conditioner compressor will not come on


So far this year our shop have seen a few of this style Grand Prix with leaky a/c condensors. The freon level is probably to low enough not to operate. With any luck the system may just need to be recharged with 134A freon.

I'm looking for the place to recharge my air conditioner on my 1993 Pontiac Grand Prix


being a 1993, it probably uses r-12 refrigerant which is baned by the epa and you probably have to be license to purchase it. best to get it serviced by a qualified tech. it is possible that the system is 134a, in which case the port will be a quick disconnect fitting on the low pressure side. the fitting for the low pressure is between the accumulator/dryer and the condenser. also the low pressure fitting is smaller the the high side. in either case if you have no experience, it's best to consult a set of instructions

R134a recharger nozzle won't fit on low pressure service port.


The low pressure port on the 2003 grand am is actually behind the engine, near the firewall on the passenger side. Good luck getting your hose down there though, I ended up buying an extension hose.
