AC not blowing cold

Post by 350matt »

Hello All

recently I 've found my AC isn't cold (as the outside temp is slowly climbing) but using a pressure gauge on the low side shows I have 22 psi in there?
do the pressure switches on these fail?
I've got a high side gauge on order so I can check compressor performance ( and the high side pressure / switch)
if I short out the pressure switch pins the compressor clutch comes on OK
