Question about 2004 Chevrolet Impala
I know it has a blower motor control processor, just wondering if there are relays involved that I could check.
Yes, generally the blower motor relay is located in backside of this devices, located under globe box (passenger side).
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.

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.

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

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!!!

The blower motor resistor is located behind the glovebox mounted in the fan housing box under the dash.

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.
