Nothing coming from the vents when you turn on the a/c, heater, or defroster


You can jumper the fan motor to make sure it runs and if it does then look at the switch or resistor. You can also remove the resistor and omh acrossed it to make sure that it hasn't blown the fuse on risistor.

Do I need to replace a sensor because my radiator fan runs all time while the car is running?


Do you have your a/c or defrost on? The fan will kick in when you run the ac or defroster.

If you are sure ac & defroster are off, then the fan sensor is suspect.

Hope this helps.

What causes my AC to kick on when I turn the heater or the defroster on?


The AC does kick on in the defroster postion or half defroster half heater. This is due to the dehumidifying effect of the AC. moisture condenses on the AC coil in the heater box and exits the car through a drain hole. This speeds up the defogging process. This is completely normal.

Kia idles rough when switching from heat to defrost also happens sometimes when driving


That's your AC compressor kicking in and out to assist in defrosting. AIS (automatic idle speed motor) should overcome that, unless it needs cleaning, or maybe a tune-up is due., I'd try cleaning throttle body with spray cleaner first to see if that in itself may help. Spray a little extra in direction of port for AIS motor.

When i turn the switch on the dash to kick on the blower motor it doesnt work. before you could wiggle the switch on and off and it would then kick on, but now it doent matter whether you wiggle it, hit it...


You need a new switch, or possibly a wire fell off. When you wiggled it, it was getting a temporary good connection. Either way you have to pull it out.

A/c kicks on when switched to defrost


I would say you have coolant loss somewhere and its not blowing out heat. Check to see if you have enough coolant. Otherwise for the ac kicking on, that might just be faulty wiring. try tracing back the wiring form the compressor and make sure you dont have any open circuits.
