Air conditioning problem

most likely that the alternator drive belt broke for the ac to stop working
if it needs gas then you have a leak that has to be fixed first

GET IT REGASSED COBB THAT WILL SORT THE PROBLEM OUT

your air condition is a "canister" of gas. you need to take it to a mechanic or shop and have it "regassed"

Multi-Diag Access J2534 has the function for air condition, such as Diagnosis of cooling electronic,
Reading settings cooling circuit,Test servo actuators

It may need regassing, air con runs out after a while as its 2005 it most likely needs to be regassed/refilled!

either the restrictor valve is a bit blocked ,or it needs regassing properly with a proper machine and the gas weighed in properly

Test new compressor. It may also be faulty, new or not.

either you have a leak, or the belt has snapped, or it needs regassing.

need to just look at a/c lines and the accumulator you should be able to find the valves fairly easy

There is a pressure sensor welded into the pipe work for the aircon with two wires coming out of it.
Unplug this and bridge the wires together when the car is running with the air con on.
If it is a faulty pressure switch you will hear the clutch on the compressor cut in and out when you touch the wires together..If this works buy a new switch..but you will have to have the car regassed.
