2004 Impala, the heater blower stopped working, bang on the dash and it worked for a while. if this sound familiar look for 12V at the blower motor when blower switch is on high. If there isn't a voltage, look at red wire to blower module it should have a constant 12V. If there wasn't a voltage, I found a bad connector under the dash behind the switch controller. It had 12V on one side and nothing on the other.

It could be a bad 12v red feed wire to module, blower motor, or the control module by the blower motor. I removed my motor and hooked it to battery to check it. I am not sure how to check module.

Hi again. Does any one have any ideas as why or what is keeping my blower motor running constantly even when the ignition is turn off and the key is removed??????
It is probably the blower motor control module is bad. It is between the firewall and the blower motor under the dash on the passenger side. Mine had some kind of plastic like pop rivets holding it on. I just took a wood chisel and cut the heads off to get it removed. You will have to reinstall the new on with screws in the other 2 holes beside the ones you cut out. Its better to get screws with bolt heads so you can use a ratchet and socket to reinstall due to limited space to use a screw driver.

Probably the blower control module under the dash and between motor and firewall on the passenger side.

I took the passenger side access panel under the glove compartment off to get to my blower motor. I tap it lightly (from underneath) and my blower motor starts working. It`s usually brushes have gone bad and just need replace motor, It`s simple to replace. I had a dealership tell me it was my heater control panel and my blower resistor to the tune of $633. WRONG!!!
It will cost me $60 to buy it and do it myself (30 minutes) and the dealership didn`t EVEN find the real problem.

Or you could try disconnecting the battery cable, wait a couple of minutes, reconnect it

I have the same problem but i replaced the blower motor and the resister and they still don't work any suggestions for that.
I am having the same issue. Dealer FSM flowchart said replace the blower motor control module, then the blower itself. Not a real waste of money because I live in florida and the A/C gets used constantly. Anyway, tracked the problem to a loose connection in the connector that plugs into the blower motor control module. It was breaking the path to ground (NOT a short - no blown fuses). I am looking for a connector to splice into it; but no luck yet. Might have to crack it open, solder the connectors together, and then resplice it back into the harness. Messy, but effective. If someone knows where to get the 5 pin connector; let me know.

I have an 04 Impala which blew smoke through the dash vents, now the blower motor doesn't work. I have no heat or a/c now. I'm not sure the car is safe to drive. Anyone out there that can help?

I had same problem. While being lazy one weekend I took 04 Impala into quick-service oil change station and was talked into having cabin air filter replaced. They did not reinstall seal properly. check it out, might help.

Blower motor not working all the time...if I bang the dash near the glove box, it comes on then works great. Is this the switch assembly, the resistor problem, or should I be replacing the blower motor?
Had the same problem . check for loose conections on motor and blower control module . with all the vibrating upstate NY in the snow & ice . both were loose . also a lot of moisture around the area .

My AC/Heat is blowing just fine but the climate control lights are not on. You can't see the red or blue climate control. Does anyone know how I can fix this issue?

I have an SS, did the bang on the dashboard by the glovebox. Works again, thank you! I will probably have to do something more technical at some point but not today.
