Fan for heater

The Fan is not coming on when I turn the heater on. You can hear it the motor switching when you turn it on different settings (floor, defrost etc.)
would that be a fuse?

I had the same problem. We bypassed the hot wire. Works fine now. It is a major flaw in Impala.

Could be a fuse. If not it could be the blower motor or the resistor. First try hitting the blower motor passenger side underdash. Some times they stick. If this works replace the blower motor if not check for power at the blower motor if no power replace resistor if you have power replace the motor.

Heater on my 2005 Chevy Impala LS was working then just stopped.... Can hear a motor under dash when changing from vent to floor to defrost


Does it work on any setting? Like 1 2 3 or 4?? If only works on say...4 then it's your resistor in the switch. Not bad easy fix. YouTube or Google it. You'll see

Nothing coming from the vents when you turn on the a/c, heater, or defroster


You can jumper the fan motor to make sure it runs and if it does then look at the switch or resistor. You can also remove the resistor and omh acrossed it to make sure that it hasn't blown the fuse on risistor.

Fan motor on heater has stopped when I switch between the settings ( defrost to upper & lower heat) I hear the gates moving but the fan won't come on ( no heat ) it's very cold please any sugestions...


first check the heater fuse...then you want to unplug the fan motor lead and run it straight to the battery...if it works then you will need to check the resistor assembly..it is located on the heater housing right near the fan..it controls the different speeds for the fan and usually has 4-6 wires coming off it. If these don't fix the problem...try looking in the fuse/relay box both in the cab and under hood to see if you have a relay for the heater fan...as it may be defective

unplug the heater motor and put a hot wire to it to check the motor if it blows if the wire gets real hot you need to change the heater blower motor. You will probably need to change the heater fan motor resistor. follow the heater fan wire and it will go to the resistor

No air coming out of the vents


It sounds like the heater motor may not be operating. When you switch the heater fan on can you hear the motor running? If not then it may have blown the heater fan fuse, check the fuse's and then try it again. If the fuse is ok then it could be a faulty switch or fan motor.

Sounds like a blower motor problem. Check for obstructions around the squirrel cage, or a broken cage.
