Is your compressor clutch kicking on? If not then I'd suspect your pressure switch. However if the clutch was not kicking on prior to having your system recharged I would wonder how the shop was even able to charge it

 

hi gus, mad fred, here have done what you suggested coming up code no"s 12 23 24 but have had front bumber of to fit new front wings maybey that has not helped , but thats why my "mates" call me mad fred

 

hi mate how right you are about my system have had it checked out by aircon expert system just of vapour and has buggered compresser so now having to find a compresser for it that will not be cheap but will cure problem, will let you know outcome

 

I am not an A/C expert but recently found that my A/C was not working. The fuse was good and the relay was replaced thinking it was not working properly preventing the A/C clutch from engaging. The problem ended up being the 4-Level pressure switch. It is my understanding that this pressure switch controls not only the compressor but the cooling fans as well. This switch prevented power to the clutch of the compressor and cooling fans when the A/C was turned on.
