My wifes 06 commander ac/heater switch only works on high speed. What can i do?

This is very likely the blower resistor. High speed bypasses the resistor but lower speeds use it. You will find it behind the glove compartment

I have only high speed on my ac/heat switch. have replace acdelco blower motor resistor 2 times already. works for a while and quits. whatelse do I need to check etc?.

If you have replaced the blower motor resistor block twice all ready, i would be replacing the blower motor itself. When the blower motor is drawing too much current it burns out resistors for lower fan speeds in resistor block, but doesnt blow fuse for fan. Also check for leaves and stuff in fan when removing fan.

How do you change the front blower motor in a 2006 jeep commander? it's gone out twice now since we bought the jeep. the first time we had a mechanic fix it because it was under warranty. but now it's gone...

why not post the symptoms.? (all, not just dead) on all speeds?
the front just unscrews. its not hard, at all. nor worth 500 bucks.
but was that $450 for motor and $50 install? cant guess that ...

did you check all fuses first (in all fuse boxes , not just one)?????
FRONT OR REAR system? wow, with not symptoms i cant guess.
blow dead on HIIGH speed,
is it manual option or climate control HVAC option?
ATC or MTC systems (a means auto, m = manual)
did you replace the blower resistor first, if low speed fails.
did the hot wire test on blower fail, , ? do say this, as wasting a non good blower, is "over the top"

ill guess, front
  1. Disconnect the negative battery cable.
  2. Remove the instrument panel silencer from the passenger side of the instrument panel.
  3. Remove the glove box from the instrument panel.
  4. Disconnect the blower motor wire harness connector from the blower motor power module or resistor, depending on how equipped.
  5. Remove the three screws that secure the blower motor to the HVAC housing.
  6. Remove the blower motor from the HVAC housing.
rear is 16 steps. so..............................

all answers by me are USA cars, (usa forum it is)
and non Diesel, yes, its diffr.

now things that cause (hot wire to blower passes my tests)
failures of blower
  1. blower relay bad,
  2. input to relay wrong.
  3. fuse blown PDC #1 F1.
  4. A/c controller not commanding blow. there are 2 of these. modules.
  5. lots more but i need your unstated facts first. all of them.
all this and more is in the FSM book or at diy for $15

Fuse 1 good , use a scan tool yet, to see if there are errors>?

Relay PDC relay blower motor front has 12vdc on in 87
ill pretend MTC, system
the 12vdc above goes to the blower, pin 1, is it>?
then the controller grounds pin 2 of blower on high
does it 0v? there? , it does so via ground G200.
if not its bad or the switch to it is bad.
the resistor block does not kill HIGH speed ever. cant. do that.
so is controller, or its switch bad, if not 0v here.
(keep in mind, my hot wire test passes on the blower )O

if 12vdc is at pin 1 on motor
you can jumper pin 2 to ground, fan will blow on
high, if not blower is bad (front)
it if blows now then the controller is bad or inputs wrong to it.
simple huh?

Ac/heater fan switch problem on a 2006 jeep commander

next to the fan motor there should be a connector that has three or four wires that attached to the blower resistor. it should have two screws holding it to heater case, just pull it out and replace.

A/c blower stays on while the car is off and is draining the battery.

Seems like you have an important short circuit. Blower is supposed to be cut off when car is shut down. I have seen blower switches melt, from excessive use of high speed blower, shorting the contacts, and staying on permanently.

AC was blowing and just stopped

Check blower motor fuse. If blown replace. Be aware. If fuse again blows or you find fuse to be in good condition it indicates a problem in blower circut/components. Do NOT replace with larger fuse to cover problem it will cause further damage. $$$
good luck
