The fan switch will not work on position 3 and 4 does not work. Position 1 2 and 5 work just fine. Do you know if there is a way to determine what the problem is?

    I have a 2003 Chevy Venture van. The front blower motor does not work on positions 3 and 4 but does work on positions 1, 2 and 5. I bought a new blower motor resistor and plugged it in but it did not solve the problem

More then likely the switch itself is bad. Chances are the contacts inside the switch are not connecting and allowing the motor to operate in those positions. If possible, try a known good switch in it's place.

You have a problem with the blower motor resistor. This is a very commen problem on all gm cars and light trucks. The part is not to pricey. You can find the resistor under the glove box buy the blower motor. Two bolts and out it comes.

Fan which blows heat doesn't work when toggle at dash board is moved to high.


When your fan switch is placed in the high position, it feeds directly to the fan motor and bypasses the blower motor relay. If the fan is operating on speed 1-3, then you have one of two things wrong, either you have a blown fuse, or the fan selector switch is faulty on the high setting.

Fan switch stopped working 1 mth after replacing the resistor


1) Check for +12v power from the fan select switch at the resistor pack - (If +12v is available there you may again have a faulty resistor pack).
2) Apply +12v directly to the fan motor to check that it runs ok.

04 Wrangler AC fan only works on high speed (position4).


Its the switch behind the fan nob thats not making contact, you have to pop the cover off the dash where the radio fan and other gizmos are. Then remove the fan nobs by pulling them straight off after that unscrew the housing unit inside is the switch. You must carefully pry this open so as not to break the plastic clips holding it together the switch thats fryed should just pop out easy replacement fan switch! If my mind serves me right it costs 40$ to replace if you order from chrysler.

When you turn the fan on in the 1 position with the a/c on the fan stops working. when the fan is switched into the 2, 3, 4 position the fan blows but the a/c cuts off. what is causing this?


something is being grounded, you need to retrace the wires and find out what is cousing the interfirance, if its not that then check the blower motor it will be located on the firewall.

If the heater fan on your car only works on "High" the problem is more than likely the resister assembly in your blower circuit or poor connections at the resister assembly. When the switch is in the "high" position the current does not flow through the resister assembly it flows directly to the coil of the blower relay. When the switch is in "low", "medium 1", or "medium 2" position the current flows through 1, 2, or all 3 of the resistors in the resistor assembly which results in the 3 different lower speeds. Check the resister assembly and replace if needed.

Heater relay


First, turn on the fan motor to high, and then tap the bottom of the motor. The brushes stick to the armature, and tapping the motor will release them. Second, check for voltage at the connector for the motor. It should be 3 VDC at position 1, 6 VDC at position 2, 9 VDC at position 3, and 12 VDC at the highest position. No voltage at 1/2 & 3 = replace the heater resistor, located in the air box between the fan & the heater core. No voltage at all? Replace the fan switch.
