ok so my air conditioning is not working...i found that there was no refrigerant in the lines and got one of them 20 dollar refill things with the gauge at walmart and recharged and refilled the lines followed directions exactly, and i went for a drive had the a/c on for quite some time about an hour and still no cold air blowing...checked to see if there still was coolant and still a positive charge in the lines..which there was...and thats where im at now..i can hear the a/c kicking on and off and all that(well i guess thats the a/c clutch) but it has coolant and a good pressure reading and no leaks... so what could be wrong.....???::w::w:

You might not have enough R134 in it. There should be just over 2lbs of coolant in there. If your a/c is just cycling its either low or the orfice valve is stuck. More than likely you just need more coolant. open your hood and watch the compressor. you should see the clutch engage and disengage as it clicks. I would try adding more coolant first.

alright well the clutch does enagage and disengage...and when i added the coolant the guage on that can thing i bought says it about 45lbs which is in the "blue zone" and anything above that could be dangerous....so do you think i should go ahead and add the entire can anyways...and where might this orifice
valve be located...thanks guys for the help..i really appreciate it

i was talking about the amount of R134 that you will use. the 45lbs that you see is the pressure. I am not sure where it is on the dodges. Most of the time its in one of the lines going into the condenser, I think its the input line. Can not remember off hand.

You should have a high/low pressure sensor on one of the lines also. That could be the relay that ole boy is talking about. It should just piggy back to one line and have two or three wires coming off of it.

i had to put two full cans of freon to get mine back up to par.
dont think the low side of the system has enough pressure to burst a can of freon.
if its THAT full, it will just no longer accept any more refrigerant, and you'll have to empty the can manually.

In the fuse box, behind the driver side battery. Mine blew last year, it operates the AC compressor clutch engagement
