There is a vacuum leak under the hood somewhere. Check the vacuum at the speed control servo. If there is no vacuum on the line with the engine running, follow the line to find the leak. The vacuum reservoir is mounted under the battery tray. I would look in that area after confirming no vacuum at the servo.

SOURCE: heating system blows only cold air

it maybe a blend door problem. if both hoses at the firewall for the heater are close in temperature its not likely a heater core. the actuator for the blend door is located on the bottom of the heater/ac box towards the middle of the bottom. it will be a tight fit but you can remove it without removing any part of the dash. take it off and disconnect the power. start the vehicle and manually move the door and see if the temp changes

SOURCE: 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.

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

1996 Montero Heater Blower not working


I assume your heater setting is electric control, if so either your defrost and floor heat switch failed or wire problem. For the air not hot, check the heat control valve on the top of the hose it should be in front of the firewall. I don't know your car is using mechanic valve or electric control valve. Anyway check there first. Good luck.

Blower motor quit working in my 06 jeep commander. still have cool air comming uot of the vents


Could be the blower motor, switch, resistor, or fuse.
Check for voltage at the blower motor after checking the fuse.

2006 jeep commander blower will not blow at all how to test or fix problem


First check all of your fuses under hood and under dash! If they are all good you need to get a new blower motor, you can get one at your local autozone, orileys, etc. not that hard to change out. should fix you right up!

Could be the control switch itself. Or possibly the actuator that moves the door from defrost to heater. With the heater on, try switching from defrost to heat and try to hear if you can hear anything in the dash operating.

It sounds like you have a blend air door stuck. This is in the housing of the heater a/c blower unit under the passenger side of the dash. There is a motor on the top of the housing that could possibly be stuck or on working.

Blower will not switch to defrost,floor,just vent,no heater


You did check for vacuum lines off, or wiring harnesses not plugged in all the way, or at all didn't you? Did you pay someone to do this, or do it yourself, because if you paid someone, have them look at all the connections .
