A/C leaks

Recommended Posts

In May i had the a/c refilled as had the rad changed over, and was working great for a couple of weeks, ive not used it since end of May and went to use it yday and its not working, did the diagnostic check and its the pressure switch it reckons, so does that mean the gas has leaked again, surly in a space of a month or so the machine would of seen a leak when it checks the sytem if its bad enough to loose all the gas in such little time? Or could it be something else?

 

Basically when you press the A/C button the light comes on but nothing else kicks in. Bit like before i had it regassed

i had the same problem and it turned out to be the schrieder valve in the low high pressure side ( or was it the High ..... never mind ) , Anyway the machine wouldn't detect this leak as when the machine is coupled upto the A/C system these valves would be depressed inwards thus breaking the little 'O' ring seal ....

 

May not be your problem but its just a thought and worth a check

 

Can't you see any of the bright green dye anywhere ?
