Re: AC not working on KIA
If you have freon full and got power to the relay the you need to check the radiator fan if working if yes the a/c cut off switch should be mounted on the a/c lines if it is two wires disconnected and jump the tow wires togather by small paper clips for few seconds and start the eng put the a/c on if started working good then you have a bad switch for 3 wires switch is to replace

check for fuse and relay problems in the ac circuit. disconnect the wire near the ac clutch and use a test light to see if there is power there. Remember that there are 3 units that will stop the clutch from working. Low pressure switch, high pressure switch and the thermostat. Best take it to an accredited ac specialist shop for a test of the system as you may have a leak and all the gas is gone.
jump the low or high pressure switchs this switchs are located on the a/c lines of tje compresor not run check power to the compresor if you have power maybe the compressor is gone
check the a/c control pannel to and take a second opinion before expend money
this cases you have to re connect in A/C S.W. if this problem comong with your vehiclefrom first time . need to check wire by code for compresor line in the socket goes to A/c s.w and re connect with + line in same socket .in case replace high presure sender on high presure line and check freon pressure / quantity 550 gm .
FIRST I CHECK ALL FUSES AND RELAY.TO BLOWER MOTOR IF IT STOP BLOWING.AND CHECK FUSE TO HVAC SWITCH CONTROL.AND CHECK FUSE / RELAY TO AC COMPRESSOR.IF FUSE / RELAY GOOD POWER GETTING TO AC COMPRESOR CLUTCH COIL AND LOW PRESSURE SIDE 28 PSI AND HIGH SIDE 200 PSI. CLUTCH COIL IS OPEN.IF REFRIGERANT LEVEL LOW YOU MAY NEED MORE REFRIGERANT.YOU NEED AT LEAST 28 PSI ON LOW SIDE AND 200 - 220 PSI ON HIGH SIDE.IF ALL IS GOOD STILL NO AC PROBLEM COULD BE A FAULTY AC CLUTCH CYCLING PRESSURE SWITCH.
U NEED TO CHECK FOR POWER AT LOW PRESURE SWITH AND A/C RELAY.U WONT GET POWER TO COMPRESSOR UNLESS RELAY IS WORKING AND SYSTEM THINKS THERE IS ENOUGH REFRIGERANT IN. USUALLY LOW PRESSURE SWITCH IS ON TOP OF RECEIVER DRIER.
