04 monte heater issue

Did you ever figure out what the issue was with the heater only working on the passenger side? I have the same issue on my 04 Monte and haven't been able to figure out what the problem is yet.

A common cause for this problem is a faulty temperature door actuator motor. There is a seperate motor for the pasenger and drivers side.
You could try to disconnect the battery for a few minute. This may cause the motor to re-set.

2005 monte carlo, heater only works on passenger side, hard to defrost windshield like that! A/C works on both sides! Help!


The heat is generated by the engine, so that should be ok. But where the warmth goes, is directed by valves, toy can change with the knobs. When one is blocked, a cable is broken or a lever came lose, you can't change the settings. I think it would be wise to let a tech look into this problem.
It must ne a mechanical problem.

check the actuator motor and make sure it is moving the doors between the heater and the ac. it is in the center of the heater inside the car and is a small motor attached to the heater housing.

Blower moter does not work ( 2004 monte carlo )


Check for power to heater motor, if you have power then you will need a new heater motor. The heater motor is located under the dash on the passengers side. You can try tapping on the motor and sometimes it will start up (short term fix). There is also a resistor in behind the heater motor but normally the fan will work on one speed if the resistor is the problem.

Water drips onto carpet on passengers side front foot area. Can be seen dripping from plastic air ducting above foot area. how to figure out how its getting in. Have replaced windshield.


You can only have 2 issues dripping water onto the passenger floor board. First being a clogged drip line for the ac evaporator. The other is a leaking heater core. Figuring out which one is the issue is fairly easy.

If your vehicle has anti freeze in it when you turn the defrosters on it will smell sweet. If it does you have a leaking heater core. If it does not then the drip line is clogged.

To clear the drip line get under the vehicle and snake the drip line on the firewall. It usually is a 90 degree rubber or plastic piece on the passenger side about a third of the way up the firewall. A leaking heater core means it has to be replaced and not really a job for someone that is not exsperienced.
