Most common problem is a bad blend door motor or re-calibration of it. Could be alot of other things so if you get more info write back.

Don't automatically assume it's low on freon. Get back to heavymetal77 as he does this for a living. I'd listen to him.

The A/C will not turn off on my 2006 Kia Sedona EX. Air blows cold, but no matter where you set the control knobs for A/C system or fan controls the A/C stays on. Even with knob in the OFF position.


Looking under the hood in engine compartment with engine running A/C off , the compressor is engaged ? If so , the A/C compressor clutch relay is stuck closed energizing the compressor clutch all the time . Now if your talking about the blower inside the car running all the time , air blowing out of the vents . The A/C isn't engaged . Could be blower motor relay stuck or the control module is bad .

Air conditioning problem

Ac is not blowing out cold air. You have to put gages on the system and it shows its has freon.Checked all fuses and relays. The two fans in engingine compartment do not come on when the ac is turned on but does when the engine gets hot. The compressor engages when turned on also.
If the magnetic clutch engages the compressor and still no cold air could be still low in freon or the HVAC unit.

Blower motor not working all the time...if I bang the dash near the glove box, it comes on then works great. Is this the switch assembly, the resistor problem, or should I be replacing the blower motor?

My air conditioner is blowing warm air on the driver side and cold on the passenger side


see this steps and think with clearly and logically NOT feared. God bless you
checkmark.gif Start with the compressor. Does it engage when you turn on the A/C?
If so, the compressor is working and the A/C system probably contains enough refrigerant to make cold air, so the problem is inside the HVAC unit. Replace the motor that controls the blend air door (this is a difficult job and best left to a professional since it involves tearing apart the HVAC unit -- about an 8 to 10 hour job!).
If the compressor does not engage when you turn on the A/C, see if it will run by jumping the compressor clutch wire directly to the battery (use a fused jumper wire). If the compressor works when you jump it, and the A/C blows cold air, the system contains refrigerant and the fault is likely a bad A/C compressor clutch relay or a bad clutch cycling switch or pressure switch.
If the compressor does not engage when you jump it, the problem is a bad compressor clutch.
If the clutch engages but the compressor does not turn (the belt will start to slip and squeal), the compressor is locked up and you need a new compressor.
If the compressor clutch engages and turns the compressor, but the A/C still does not blow cold air, the system is probably low on refrigerant and needs to be recharged.

Heater / air conditioner fan control doesn't engage fan. Previously, it only worked in high speed.


I would replace the blower motor resistor first then see if that corrects this. The resistor is located next to the blower motor under the dash.

Problem with heating and air conditioning. The driver's side is blowing hot air and the passenger side is blowing cold air


Air Conditioner blows warm air
  1. Air conditioner system is discharged. Have the system evacuated, charged and leak tested by an MVAC certified technician, utilizing approved recovery/recycling equipment. Repair as necessary.
  2. Air conditioner compressor clutch not engaging. Check compressor clutch wiring, electrical connections and compressor clutch, and repair or replace as necessary.

A/C FAN NOT WORKING


I presume you are talking about the blower motor and not the cooling fan on the engine?

If you have checked the fuse then ensure there is power at the blower motor when switched on.
