On the 2.4l engine the low side is located on the line coming off the compressor itself. reaching from underneath seems easiest

Where exactly is the low port for the air conditioner on a 1998 Pontiac grand am

Normally you cannot charge the high port as the connection will not fit. Also if the A/C is working the high port gets much hotter than the low port. Also on the plastic cap it will have an L on the low pressure port and an H on the high pressure side. Do not try to recharge it unless you are 100% sure. If you are needing to recharge the system then it has a leak that needs to be repaired. It is technically illegal to add refrigerant to a system with a leak without first repairing the leak. So, my advice is to get the leak fixed first and then have the system charged by a professional with the proper equipment and training. But the choice is yours.

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.

Where do I recharge ac at

there are 2 ports one for low pressure and one for high pressure. the low pressure is bigger in diameter and is usually close to the dryer and or fender and firewall. the high pressure is near the condensor on the fron of the vehicle. if there are caps for the ports low will be blue and high will be red. low side pressure should be 35-50 psi and high pressure should be 135-150 psi
