Question about 2004 Pontiac Grand Am

1 Answer

Vent fan is not shutting off

The fan that circulates air in the cabin of my 2004 grand prix is not shutting off; not when the fan switch is in the off position, and not when the car isn't running. What could be the possible reasons for this occuring? I am afraid that the battery is going to die if this problem isn't fixed.

The blower motor speed control module is most likely shorted. This is very common on the gm w-body cars such as your grand prix.

Order and install a new blower motor speed control module and install. It is located in the hvac box, passenger side, near the blower motor.

Blower motor working on all 4 speeds but air only circulates through the defrost. No air circulation at floor or top vent outlets.


No vacuum to switch. The system uses vacuum from the intake manifold to operate the various vent doors. Look under the hood for the small vacuum line that goes into the firewall near the A/C lines--there may be some other ones there a different color, but only one--usually black--goes to the intake manifold vacuum port. Make sure it's hooked up and not leaking there. If that's OK, see if you can get behind the control switch in the cabin. The line may have come loose there, or perhaps your switch is leaking there.

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.

Hot air forced into cabin while driving 92 saab 900


the air distribution switch controls the air distribution and the fan, distribution switch in the 0 (straight down position) will be off. Car movement forces air into teh body, but with teh fan off there will be no air when the car stops. Does the fan run when the distribution switch is in any other position? it should respond to the speed settings of the fan switch.

There is a vacuum bottle accumulator that assists the distribution switch, sometimes this gets disconnected and the switch settings don't work.

Do you hear any noises if you turn the distribution knob while the car is running? suction noises, or flaps opening?

If not, then you likely have a vacuum problem (check for a white bottle in left front wheel housing, except convertible -> under the spare wheel, tank should have one or two vacuum lines connected to it (one for convertible). A disconnected or leaky line is the most likely cause.

Possible other causes are faulty air distribution switch; burned out fan motor; inoperative vacuum solenoid motors controlling air distribution flaps.

But check the vacuum accumulator first, if under the spare wheel, the lines are easily dislodged.
