    At first only control number 5 did not work now none of the controls 1- 5 work. I checked the fuses and all are O.K. Where do I go to check the fan switch?
    Thanks,
    Arturo

    I have a 2006 GMC Sierra - Fan switch has 5 settings - Does not work on #5 - Going from 4 to 5 I hear a click in the fan relay comming from under glove box.

    I have the same problem. Works 1-4 but no 5. I replaced the resistor and the pigtail. ( the connectors were burned) made sure all connections were good and put everything back togeather. When I turned the fan to 5 it shut off again and has a clicking sound. could it be something else or could I have gotten a defective part from the dealer.

My fan blower will not work on high speed on my chevy 2005 silverado


if you got heat on all speeds and the blower motor is working properly then you probably need a new HVAC switch.

My blower control switch only works on level 4 or the highest setting. could there be a loose connectror while I still get resistance and


Hi J, I believe the problem is with the resistor inside the the climate box. If you remove the covers from the side of the center consul and look carefully at the heater unit you should see a small panel (Maybe two inches square) with an electrical connection attached. Remove the plug and then the retaining screw and withdraw the unit. On the back of it you will see wire wound resistors. These are for the lower speeds of the interior fan operation and if blown the fan will only operate at the highest speed. either replace the unit or reconnect the broken wires and refit. Regards John

2006 Chevy 2500hd. Fan speed control switch will not work at 5 setting. Will not work for a short period and then kick back on. would the entire module need to be replaced or is there a cheaper solution...


Can you say recall notice? Chevy knows about this problem and has extended the warranty through 2016 or 150,000 miles. Just had my 2006 Silverado fixed at dealership @ no cost to me. It takes the shop approximately 45 minutes to correct.

2002 Honda Odyssey fan only works at high speed. The A/C compress


Usually when the blower fan only operates on hi speed, its because of a failed blower motor resistor. You still have hi speed because on hi, the power going to the blower motor goes directly to it, as opposed to the lower speeds, when the power is routed through the resistor, thus lowering the voltage, which in turn lowers the speed of the fan. The resistor is usually located near the blower motor itself, under the hood back near the firewall.

The fan/blower only works on the high setting.


It probably is the fan switch itself. They are around $30. for a new one. You can take it out and check to see if you have power to all the settings with a ohm meter or test light. They are not real hard to take out.

Heater/ac switch speeds 1 and 2 don not work in 99 Silverado


you need a resister found under your air duct by the passenger floor under dash board auto zone sells these for about 25.00 you may as well buy cabin air filters while your at it . 1 of the screws will be a pain to install back into the duct work I left mine out didn,t make a difference . you might have to order it as they are a comman item oh you will need a vacuum to clean up mess from cabin air filters .this is not a hard job .

A/c heater climat control switch


Check the relais module located inside under the rh side of the heather box you can see the connector most of them need to be replaced as they burn out you may need to replace the blower motor as well,high amp draw caused by faulty bearings will overload the blower motor controller

Fan speed switch only works on #5


Call your local GMC Dealer and see if they have the climate control panel in stock. What happens is the circuit board on the back of the panel shorts out. The panel comes as an assembly and is very easy to replace. Don't go with a wrecking yard piece. I made that mistake once and it didn't work either. I got one from the Chevy dealer and it worked perfectly.
