Question about 2004 Chevrolet Impala

Does the blower motor in my 2004 chevy impala have relays ?

I know it has a blower motor control processor, just wondering if there are relays involved that I could check.

    Not sure if relays in the fusebox under the hood are involved.

  • Rich Feb 16, 2012

    Besides the blower motor control processor are there also relays?

  • Rich Feb 17, 2012

    So you're sayin that the only thing between the battery and the blower motor is this motor control processor? There aren't any relays involved in the fuse box under the hood? Thanks, Rich

    That's the resistor under the glovebox next to the fan, not the relay. The 30 amp relay is under the hood. There is also a 10 amp fuse in the interior fuse panel. The HVAC controller is connected to the 10amp fuse. The 10amp fuse is connected to the 30amp relay. The 30amp relay is connected to the blower motor resistor. The blower motor resistor is connected to the blower fan. Those bones, those bone, those bones.

SOURCE: 2002 Chevy Impala Blower resistor location

It is on the passenger side, you have to remove the black plastic kick plate, below the glove box, to expose it (held in place with 2 latches and 1 push pin). The resistor is in front of the blower motor ( sandwiched between the motor housing and the firewall) it is tricky to get to, i think when i changed mine i didnt replace all the screws as they were difficult to remove and even harder to replace. Good Luck, Mike

SOURCE: replacing resister on blower motor

if you take off the kick panel, below the glove box, off and can see the blower motor, you are half way there. The resistor is between the blower motor and the firewall (towards the very very front of the car). You really almost have to have you head where you feet are to see it. You can follow the big black wire leading to it, you'll find it, It is a bear to get to and if I recall I skipped putting back one of the screws after replacing the resistor as it was not worth the hassle of trying to get the last one in.
Good luck, Mike

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: which fuse box has blower motor fuse on 2001 chev impala

There is a blower motor resistor located up under the passenger side dash. I believe there is actually 3 fuses that can cause problems with the blower....relays/fuses should be located in the engine compartment fuse block. They are High Blower fuse-HVAC fuse-Radio/HVAC/RFA/Cluster/etc...fuse. Hope this helps.

2008 Impala blower don't work


You probably have a bad blower motor control module .First check the Batt. 4 fuse 30amp in the under hood fuse box .
Blower Motor Control Processor The blower motor control processor is an interface between the HVAC control module and the blower motor. The blower motor speed control, battery positive and ground circuits enable the control processor to operate. The HVAC control module provides a pulse width modulation (PWM) signal to the blower motor speed control processor in order to command the blower motor speed. The processor supplies 12 volts to the blower motor through the blower motor voltage supply circuit. The control processor uses the blower motor ground or low reference as a low side control to adjust the blower motor speed.

My 2004 Chevy Impalas blower won't come on until 5 or 10 min. Show me how to change the blower, Please


It sounds like a loose connection. When it warms up, the heat causes expansion and allows the circuit to be completed. This could be at the resistor pack / speed control. In any case, you might want to read this discussion:

Your impala doesn't have a resistor , it has a blower motor control processor and it doesn't work the way you think it does

Blower moter quit on 2004 chevy impala


If the blower runs on the highest speed setting, a stepped resistor has failed that allows for the different speeds. If it won't run at all and the fuse for that circuit is OK, then either the blower motor, the switch, or a relay servicing it has failed.

2004 impala blower motor


The purple wire voltage, black wire is ground, at the blower motor. At the blower motor control processor, the red wire is a fuse protected circuit, hot all the time. With hvac off, if nothing on the speed control circuit, doesn't the problem have to be the control processor? Do you see it differently? Just my opinion.
