2003 Chevy AC Fan Blower Motor troubleshooting

The A/C, heater, & vent fan does not blow. Does this mean it is the fan blower motor or some type of resistor is not working and needs to be replaced? If so how hard is it to fix?

My heater and a/c are not working. The car is not overheating and the cabin gets warm when the engine heats up. What could the problem be please?


Hi Cheri, do you mean the fan is not blowing air out of the air vents?

if so could be one of three problems;
(1) blown fuse on a/c heater circuit.
(2) sized or faulty blower/ fan motor.
(3) faulty fan speed resistor.

Where is the heater resistor on a 2005 dodge dakota? Behind glove box?


should be just above the blower motor. You will need to remove the glove box door to gain access.

Heater and ac sometimes won't work til i drive for awhile


Many of those type trucks have a fuel gauge issue...I don't think it is in relation to your heat and cool problem...I know people have had to change the complete fuel sending unit assembly to fix gauge...It wasn't cheap...Should have been a recall but it wasnt...However I don't have enough info for the heat/cool problem...Is the blower motor running all the time or does it not run until you drive for awhile..?..Some blower motors that go bad won't come on until they are jarred or tapped with a hammer...Maybe it is vibrated while driving and finally comes on...You have to listen closely to make sure if it comes on when you turn it on...If it always turns on when you flip the switch then it sounds that your HVAC blend vent doors are very slowly opening...This could mean the door actuators are wearing out or the plastic vent doors are contaminated at the hinge and slowly opening.......So check the blower motor operation first...If it don't blow until you drive the motor is going bad...First make sure all fuses have a good connection..sometimes they vibrate out...Also blower motor relays.If a blower motor relay is bad the blower will not come on at all....A faulty relay will not work the fan at all....If the blower motor comes on when it wants to it has to be a bad motor or improper connection....Sometimes a motor will operate but doesn't blow..This could mean the fan has torn loose from motor....Best way to troubleshoot blower motor is remove it,inspect fan connection...,hold it safely in your hand while an assistant turns it on.....Good luck..

Air conditioner/heater/vent will not blow air or turn on


Check for full battery voltage at the resistor block, it should have it any time the engine is on, If you don't have voltage to any of the connectors, there is usually a blower motor relay that needs to be checked if all fuses checked out as good.
If it DOES have voltage to the resistor, put the blower speed to full high and check for voltage to the blower motor, if none, then there is a circuit failure, if there is voltage, check the ground side of the blower with an ohm meter, it should read near zero ohms resistance.

Heater fan not working


The three most common problems for heater fans are
  1. Burned-out blower motor resistor. This is usually located on the engine side of the firewall. Sometimes one section of the resistor is burned out but others are still good, so the blower only works on the highest speed settings. If you have a burned-out resistor, check the blower bearings to make sure they are not stiff and causing the motor to draw too much current.
  2. The blower is actually working, but either the intake vent is plugged (I've seen vehicles with the heater core completely blocked by dirt, leaves and insects that came in through the vent), or the heater door is stuck closed.
  3. The motor bearings have gone bad (see # 1). This can cause the fuse to blow, although the resistor usually fries first.
I'm not sure how your car's cabin environmental control system is fused. Check any fuse that might apply, such as Vent/AC, HTR, FAN, etc. Generally you can identify the state of a blade-type fuse by inspection without removing it. If you have a blown fuse, check the blower motor before wasting money on a new fuse that will probably blow. Like any fan, it's supposed to turn easily, and there should not be any roughness or side-slop in the bearings.
