    My 2004 silverado only works on high as well. 0,1,2,&3 do nothing, only 4 and 5 work. Also it takes quite a while to get the heat after it's on....whats going on.

    Can I purchase a resistor, or can it be reset? I have same problem with my 2003 Silverado. Settings 1-2 don't work....3-4-5 work fine for both ac and heat.

Most likely is the resistor when they fault the default to high giving you off and high only

2003 chevy 1500 ss only blows cold air no heat


Dual climate control on these is not a manual valve adjuster. It is done electronicly with a electric motor on a valve instead of ran by a maual cable. Find this and check the plug for a 12 volt signal. If you are getting a signal replace the valve, if not it could be a blown fuse, cut wire, or a bad climate contol switch.

Fan control knob on a/c and heater will only run on high speed. 2003 dodge mini van


I replaced the fan module under the glovebox on my 2005 Town & Country last night. Mine would not shut off at all with key on. It only blew on high no matter where I set the switch. Mine also had the climate control which makes a difference. If it is not the auto climate control it is usually the blower resistor if the other fan speed selections don't blow at all except on high.

Hi, sounds like your blower motor resistor needs to be replaced. If not the resistor, check the blower motor.

2004 chevy tahoe, dual climate control, blowing different temps


Its more then likely the temp door broken or temp door motor broken/stuck. There is 2-3 of these motors under the dash on the side of the evap/heater core box. Some require extensive labor to replace, good luck

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
