This is a long shot but you could check the fuse for the heater. The fans may work on a separate fuse which is why there no heat.

SOURCE: bad smell in air vent chevy impala

It is not fixed by an aerosol or scent additive to the air in the cabin. It will only mask the smell for a period of time.

Your cause is the air filter for the A/C system. You can buy a new one at local auto stores.

To replace it, you will need to open your hood. On the passenger side of the car, look just under the windshield at the trim panel under the wipers. You will see several tabs holding down this particular side of the trim piece. Using a phillips head screwdriver, gently rotate the screw pieces out of the tab holder (if this doesn't get it, you'll need to use a small flat head in unison to apply pressure to the screw to come out). There are 3. Once these are removes, gently pull the hood rubber gasket seal up and place out of the way. Note: you won't need to remove it from the car, just enough to clear the trim piece. Remove the trim and you will see a filter. Remove the filter and replace. Installation of trim is reverse.

That will fix your mildew smell from the vents. This WILL NOT fix a mildew smell if caused by interior mildew.

Note: The directions to change this filter are also found in your Owner's Manual if you have it. It is a simple procedure and should take about 15 minutes if you are taking your time.

Thanks for the inquiry.

If it will not switch to any different positions,and you did not have this problem prior to repair.Check for a leaking vacuum line to the control unit.The line should run through the firewall to the control unit.Good Luck!!!

SOURCE: 2004 chevy subarban blows cold air on one side hot air on other side

i was a GM mechanic for many years, the problem you are having is one of your mode door actuators has gone bad, most of the time it is the actuator on the drivers side that causes the problems, i have seen this many times, sometimes you can take it to the dealer and they can hook the computer up to it and recalibrate it but most times it has to be replaced , it is located under the dash in the area above your gas pedal.

SOURCE: 2004 Chevy Impala no heat from defrost or heater

No heat is often a symptom of low coolant, usually followed by overheat. There are other controls that regulate heater, but right now, re-fill the cooling system with engine running and heater on high, then check for leaks (coolant you lost went somewhere...you need to determine where) Low coolant will damage your engine. Take care of that first, then if heater still does not work, then do diagnosis on that. (if you loose the engine heat won't matter, will it!)

Cold and hot air through air conditioner at the same time


In a car the heat and filter both go through the same filter. In homes there are normally separate filters for the air and heat.--------------------------------------------------------------------------------------

No matter what setting you have the air or heat on, it still comes out all the settings(vents, defrost and floor vents) all blow at same time in my 2003 chevy impala


sounds like you have a bad blend door motor that is stuck in the middle allowing for all vents to blow air... locate the motor under the dash and remove it. manually move the lever and see if it changes the flow.. check for power at that motor to make sure your getting the signal from the dash then you'll have found your problem....

Gets hot on passenger side stays cold on drivers side on 2004 chevy impala


Possible that the vent is blocked if you meant that the car is not cooling with the AC. If so check the flow of air on the vent , remove and clean the vent.
However if there is heat coming in to the passenger side then the engine room insulation can be open or there is a possible leak from the engine room that allows hot air to flow into the passenger side than the driver side.
I hope this was what you meant, if not clarify once again.

2005 Chevy Impala driver's side heat blows cold, but works on passenger side. Was told a vent is probably not opening to allow for the heat to get to the driver's side? Where can I locate this vent?


First....buy a drivers side air flow actuator at a auto parts place for dual zone heating/cooling.
(NAPA etc will have it.....or the dealer)
Open the glove compartment.....all the way....you may have to take the screws out at the bottom......look in at the heater assembly....look over to the left....you will see the two air flow actuators.
Look at the part you have and match it to the part on the heater assembly.
The actuator that is closest to the engine is the drivers side control.
Replace it.
Try your controls and check for heat and cooling on both sides.
The stepper motor in these actuators goes bad on quite a few...but over look that.....you have a great car,good for many miles of trouble free driving.
