The high side should have a black cap with a letter H on it.... if you dont see it then look for 2 valves that have caps on them, the larger of the valve is the high side, the smaller is the low side, the low side is the only one you want to use if you are refilling the system you do not want to mess with the highside... the low side pressure makes it so you can recharge the system, the highside will not work to refill a system if you are using the store bought recharging systems... and the valve on the recharger will only fit low side... hope this helps you... the highside should be on the pass. side towards the rear o the engine...

Where is the port located to put in freon


There are two lines running on the driverside. The high side is on top and the low side is below that by the battery. The low side is where you charge it at unless you have a a/c machine. The lowside will have a smaller port than the highside line.

This is called an orfice tube, this is located on the highside line,(small line) its located at the connection going to evaporater core, remove the line and look inside the line, note make sure system is drained of freon before removing lines, also take note of the way the tube or filter goes into the line its important that you slide new filter in the same way.

Ac dont cool ,need specs ,highside is 150 psi,low side is 0 ,at idle ac max on


Is your compressor cycleing repeatedly or is it staying on. Or, is it not moving at all. If it isn't cycling or moving at all you need to top off your system charge.

Where is the low side service port on a 2003 grand am (6cyl)


If your talking about the low side sevice port to charge your ac, its easy to find. With your recharge kit, it comes with a nozzle to attach to this lowside port. Each port, (lowside and highside), are different diameters. The charging nozzle will ONLY fit onto the lowside port. Just run the length of your ac lines from the compressor and trace them back to the firewall. You should find both ports before you hit the firewall.
