Customer Question

My a/c is blowing hot air from 3 out of 4 front vents when on full cold .
when the a/c is off it is still blowing hot air from the lower vents. I got on some forums and it seems to be either the temp controller or sensor failure, have you heard of this?

Hello and thanks for using

We may have a problem with the climate module or heater control valve as that is what controls the flow of hot coolant to the heater core. If you have a test light and digital multimeter we can test the circuit. I also recommend we have a shop check the pressures with a set of gauges. Let me know.
