Okay so I have a problem on my Dodge journey that it blows hot air and we checked the relays and the fans and then do turn on but the compressor doesn't kick on at all.. ran out of options .. can anyone help
SOURCE: how much 134a freon does the F250 use?
Hello, I see you are trying to charge the ac on you truck ,but this is not a job that just anyone can attempt and get it right. You must add factors in like is there the right amount of oil in system, is there any freon already in the system, or will there need to be a vaccum pulled on the system. If the system is completely out you must pull a vaccum for 30 minutes on the system, or either there will be moisture in the system and that can do alot off damage to an ac system. If you have never charged an ac system please let take it to someone who has. It will save you in the long run and if it is leaking they may find it as well.

You find the AC low pressure at the top of the compressor, orientated toward you , facing the front of the
vehicle. You can also follow the compressor line to reach the port.
The valve is covered a plastic cap covering it.
Near the compressor you find two ports, the high port and low port.
To find out which one is the low port, run the air conditioner for a couple of minutes withthe engine on.
Then turn off the care and touch the lines from compressor to the two ports covered with
plastic caps. Only one of the pipes will be cold, the cold line will lead you to the low port.
Regards.

follow the larger ac line of the to sizes until u come to a port it is the low side ,is the smaller port this is what u want
SOURCE: locating the High side and Low side AC gas ports
Easy. find the compressor. The larger hose attaching to the compressor is the "suction" side. This is where you install the refrigerant.
The smaller hose, whether rubber or metal as it travels to the passenger compartment, is the high pressure side.
After installing refrigerant and as the compressor is running, the larger hose will feel cool and the pressure side will feel hot.

If the compressor will run turn it on and let it run for a few minutes, the line that gets cold is the low pressure side, this is usually the one closest to the firewall. The reason that they are 6 inches apart is that they are on opposite sides of the orfice tube, hence one is high pressure and one is low.
