The AC/heater blower motor will not come on. There are no blown fuses in either fuse block, that I can see. I cannot find the blower relay.

Hey Larry,

Here is a guide that can help you test the blower motor and circuit.

Did you find the relay?

Thanks Ken,
I found the relay, replaced it but it didn't help. If it hadn't have rained all day today I would have removed the blower motor. I will let you know if that fixes the problem. Hate let my wife drive it without being able to use the defrost function.

Check to see if there is power coming to the blower first before replacing it. If this is auto temp control where you set temp then it HAS to be scanned by a mechanic to see what is wrong with the unit.

Hey Larry,

Here is a complete wiring diagram for the car, check for power at the relay first then go from there. It looks like there is a fusible link 30 amp, check there first.

Please let us know what you find so it will help others.

Best, Ken

Thanks Ken, the blower motor runs when wired directly to the battery, and I have 9.4 volts at the connector, but still won't run using the control panel. So I guess it's back to Kia to have them check it out.

I replaced the blower relay, just incase it was bad or weak. Other than the battery ground I haven't.

Thanks, Larry
