The resistor is in line to the blower motor harness near the motor itself.

1997 chevy silverado blower only works on high and then stops working after a few minutes. High is also very weak.

This is likely a common problem associated with the blower motor resistor pack.

When one of the resitors go bad it will only work on a higher setting, until all of the resitors go bad.

The part is not expensive, typically around $30-$40. In most cases it can be replace by you.

Sometimes it can also cause the fan speed switch on your dashboar to go bad, but this is not typical.

Check out this video from showing how to replace the resitor pack: 1A Auto Demonstrates how to change...

I have a 2002 Ton and country minivan. The blower fan is running at the same speed while the ignition is on. The blower fan cannot be turned off or the speed adjusted by the switch. Is this a switch...

it sounds like the blower motor resistor is bad . it is located behind the glove box and is very easy to replace. i think it was about 40 bucks. i hope this helps .

My fan won't blow out heat or air where to purchase one-

First try this turn ignition and fan switches on then pull and wiggle on the wire connector going to the blower motor resistor.These pigtails get very hot and usally melt causing it to loose its connection.The blower motor resistor is usally mounted on the heat duct on passenger side with 2 screws.You should be able pick one up at your local autoparts store but,if you can'nt then you can get one from

The blower/fan control only works in position 4 & 5, is this a switch or circuit card?

Its more than likely a poor connection at the blower motor resistor.Its mounted on the heat duct on the passenger side with 2 screws.I would first turn the ignition and fan switches on with the fan switch on #2 or 3 then wiggle the connector on the blower motor resistor.These resistors get hot and melt the pigtail and usally loose there connection.

The fan switch only works on level 5 out of 5... is this the selector switch?

You probably have a faulty blower motor resistor, this electronic part controls blower motor fan speed. This part is located near the blower motor, unhook the electrical connection and you will see 2 screws holding the part in place. This part looks like some type of circuit board, Good luck, Gary

Heater/AC fan only works on the 4 and 5 settings. Is it the switch? Fan runs well.

Either the switch or the resistors on the blower. Get shop manual remove switch and jump terminals the manual tells you to do to check switch. If a-ok then do checks for the resitor on the blower motor. Hopefully its the switch.
Good luck

'99 Plymouth Grand Voyager fan switch issues

The problem is not with the switch, it's the blower motor resistor. The resistor is usually located in duct work near the blower motor. It will have 4or 5 wires going to it and is held in place with a couple screws. These things generate heat, so they put them in duct work so the fan blows air across them to keep them cool. Sometimes the plug gets hot and melts, you should be able to buy the resitor and the plug with wires (pig tail) from an auto parts store or a dealer. The resistors are usually about $50 the pig tail is about $30.
