Question about 1995 Pontiac Grand Am

1 Answer

Heater works ok but wont send air thru defrost vents

I own a 1995 Pontiac Grand Am. The radiator cracked and I had to have a new radiator installed, yesterday, 31Dec08. With the new radiator, the heater works okay, but I cannot direct the heater airflow with the right heater control knob. The heater only projects an airflow through the instrument panel outlets. When I put the dial to defrost, no air comes out of the defroster vents, the airflow continues to come out of the instrumet panel outlets only. It is as if the control knob only operates in the "vent" mode, no matter where I position the dial.

    The control knob is fully functional. It seems odd that the problem ocurred immediately after the radiator was changed.

The A/C pump starts when i move heater controls to defrost or mix


Great question dustin but the A/C is suppose to come on in defrost or mix mode- this is floor & defrost. Does not seem to make sense does it. One of the things the a/c does is remove the moisture from the air. You need warm DRY air to remove the moisture from the windows. An automotive H.V.A.C. ( Heating,Ventilation,Air conditioning) first forces air thru the a/c evaporator core then thru the heater core and out the selected vent. If you only want a/c a blend door will by-pass the heater core which is controlled by a hot/cold knob or digital temp cotrol on the dash. Now back to the cold air problem- assuming the basics are all ok- Coolant is full, Engine gets up to proper operating temp-around 195 degrees- upper radiator should be hot. Both heater hoses should be hot. If thats all OK the blend door might not be working. It is controlled by an electric motor called a Blend Door Actuator which are prone to fail. I have replaced many on ford vehicles. Hope this helps

Heater not working on 2010 f-150


If both heater hoses are hot, and the radiator is full of coolant, it may be a blend door problem under the dash.
The blend doors direct air thru the heater core and out thru the vents.
It may still be under Ford warranty.

Why wont the heater blow out hot air in my 1995 pontiac bonneville. it will only blow cool air


If the heater hoses are getting hot, the problem may be a faulty blend door under the dash. The blend doors direct air thru the heater core and the vents.

2003 Grand Prix not blowing hot air. Does the heater coil need to be replaced? If so where is it located?


If the heater coil was bad, it would be leaking radiator fluid... probably into your dash/floorboard (depending on where it is installed in your model car). There is a switch that diverts the hot radiator fluid through the heater coil when you want heat. There is also an air diverter valve that helps to mix the hot and cold air. The fluid valve is controlled by the A/C settings control. The one that you use to choose between heater/air conditioner/vent/ defrost. The air diverter is controlled by the temp mixing controller. The most simple explanation is that one of those valves or the controller of one of those valves is not working. If the hot water cant be diverted through the heater coil, the coil can't exchange the heat (warming the air). If the air diverter (hot/cold controller) cant move to add heat, then all you will feel is air from the vent side (from outside) or from the A/C cooling the air.

I would guess that its either a controller or one of the valves themselves. Odds are, it is a controller. That tends to be what malfunctions first.

2005 Grand Prix heater works fine when blower is off-air coming thru vent gets hot; once blower is turned on air turns cold. Why?


Sounds like a clogged heater core- insufficient coolant circulating through heater core, and as soon as you blow air past the core, it get cooled off.
