Question about 2005 Chevrolet Avalanche

1 Answer

Blower works intermittant when on auto or manual

Air blower will not blow when fan is turned on sometimes, when on auto will blow very slow, then will blow full blast and runs after truck is off.

You can turn the truck off and take the key out of the ignition and open the door and the fan was still going.

When I came home from work I started the truck and the fan is very very low and as I increased the fan it would not go up.

I checked all of the fuses, they are good.

The climate control is full automatic.

Not sure which fan you mean. Engine cooling fan is different from heat/air blower fan.

2002 grand caravan blower motor intermittent replaced resistor


in review
the fan speed resistor is new
you bench tested the blower motor
12 volts test ..only runs it at full speed
if cabin filer want changed the blower motor would run hotter

could be the motor brushes or bush/motor bearing when slowed
you might want to inspect the brushes and clean the dust out of the motor
if no better
does that have climate control ?
might be the fan switch itself or the earth isnt so good

Heater fan blowing intermittently or not at all


Most likely it does, if you can hit the motor and it will run. I can't say for sure but you might want to chk. to see if you got a heater blower motor resister. There located (if its got one) around the heater motor and it controls blower speeds, might be worth checking out.
