Hi everyone,

 

Air con compressor not working, fuses and relay coil are ok but relay not pulling in. I have removed relay and checked for voltage to the coil legs when the auto button is pressed, there is no voltage. where does the feed come from before the relay? I can hear a faint click and there is an increase in revs but nothing else.

Sounds like the system may not have enough refriderant pressure, the low pressure switch will not allow the compressor to cut in via the relay as a safety, try carefull depressing the schrader valve by the battery, would hazzard a guess there will be little or no pressure.

 

A full pressure test will be required to see if there is a leak anywhere, once cured the system will need vacuuming and refilling with the correct or alternative refridgerant dependant upon the age of your zed.
