Kia Troubleshooting Questions? Ask a Mechanic
Ok, does yours have manual or automatic climate controls?
And does it have separate temperature control for the driver and passenger side?
With the ac running, are the metal lines going to the firewall in the engine compartment cold?
Ok, so it is blowing cold out the vents right now, correct?
Ok, the AC switch contacts may be worn and didnt make good contact to kick on the ac, or the control unit is not sending consistent signal to the temperature blend doors.
It shouldnt need a recharge as it is blowing cold when it works, which seems to have been consistent until today.
This is going to be an electrical issue, either in the control panel or possibly at the ecm, or in the wiring.
With it working right now, we really cant do any testing as it will show as being good for any tests.
That points to the compressor not getting the signal immediately when ac is selected at the control panel. The signal goes from the control panel to the ecm, and then to the compressor clutch relay and then to the compressor
Hi Im David, You said you are hearing a ticking noise behind the dash? being that your ac is intermittently blowing cold air and there seems to be a good charge, I believe you are having an issue with the blend door actuator. that ticking means that the arm that controls the blend door is eithe popped off or about to.
do you still need assistance?
whats with the caps??
