Why do your ac blower only work on high on your 1996 Chevy impala SS?
faulty blower motor resistor
I have a 2004 Chevy Colorado blower motor only works on high speed only?
Probably your blower motor speed resister is burned out.
On a 2005 Chevy Silverado the high speed on the blower?
What about it? Need more info.
What would cause your blower motor to work on only one speed on a 97 Chevy k1500?
If the one speed it works on is high speed, it is the blower motor speed resisitor that is bad.
What is wrong if your blower fan motor only works on high speed on a 2002 Chevy suburban?
blower resistor is bad
How do you fix a 1995 Chevy truck blower that will blow on every setting but high?
Replace the high speed relay.
Is there a relay switch for the heater on a 1994 Chevy truck?
Only for the high speed blower function. The lower speeds go thru the blower motor speed resister.
How do you get your blower to work on your 2007 Chevy Impala LS?
look in owners manual for a fuse that might control motor, could be a bad motor or a bad switch, these cars are known for the multi speed resistor going bad but when it fails high speed still works
Fan blower switch for 2002 Chevy impala ac and heater only works in high position already replaced unit with new one?
Defective blower motor resistor pack.
How do you fix heater fan when it stops working on a 1994 Chevy s10?
If you have no blower speeds at all, first check the fuse. If the fuse is okay I would suspect the blower speed switch and its electrical plug has melted. If the switch checks okay I would suspect the blower motor is bad. If you have high speed only, I would replace the blower motor speed resistor. If you have all lower blower speeds but no high speed, replace the high speed relay.
What causes the blower on a 2001 Chevy Silverado to work on high but not on low?
the blower fan rheostat usually located in blower box is like a resistor that draws energy from the blower fan supply to slow it down and there is a high speed fan relay for the fastest speed. So your rheostat is not working
Why does the Ac blower stop on my 1997 Chevy s10?
There is a replaceable resistor which is in the engine compartment located on the blower. It is usually fastened by two small screws. Remove the electrical connectors and get a replacement. If the resistor is burned out you will still have high speed. If you have the lower speeds but no high speed, replace the blower motor high speed relay. If you have no speeds at all I would suspect either the blower speed switch and its electrical plug is at fault or the blower motor itself is bad.
