There is a resistor in the system, that controls your speeds. When it malfunctions you usually end up with high only. Not 100% where yours is, but will see what i can confirm. In meantime, if you check with autozone or similar parts supplier or even dealer, they should be able to tell you where to find it for sure. Most common spots are on firewall under hood on passenger side, and some are on the heater housing up under dash on passenger side. See what I can confirm, and get back to you.

    Appears your is up behind glove box area, and the resistor is at the blower motor connection area. Dealer should be able to tell you for sure whether resistor can be purchased separately, or has to be purchased as part motor complete.

This is caused by the blow motor speed control resistor being buned out, it is located near the blower motor

Your blower motor resistor is bad stop by a dealer in the parts department and have them show you one and at the same time they can show you where it is located in your car.

SOURCE: 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.

SOURCE: 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 .

SOURCE: only 4 & 5 speeds work on the AC fan

There is a blower control module in the heater case that is known for going bad.Also it will sometimes burn where the connector plugs in.

SOURCE: 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.

SOURCE: There are 5 speeds on the AC/heater fan. First,

you will find a blower resistor near the blower motor , it goes into tho the housing with a harness of 5 or 6 wires, replace it
