2007 Jeep Commander Q&A
2007 Jeep Commander Question: air venting
Here are a few facts. When the a/c is on, it works great. When the heat is on it works great. Here are the two problems though. Problem #1- When I am driving, there is air flowing through the vents, even if the fan is in "off" mode. Problem #2- after turning off the heat...it still continues to come out of the lower vents. Any ideas??? thank you very much - Commander2007
If we were talking about my Honda or Toyota truck, that sounds normal. In most cars, turning the fan off simply turns off the blower motor (fan). Air still flows freely through the system if you're going down the road. It is basically like an open vent. The answer to your next question is similar. If you turn the fan off, and do not adjust the heat setting, the air still flows past the heater core to warm the air. The only way I have found to stop the airflow in my vehicles is to change the mode to recirculate because it closes the external HVAC intake on the car. - 4wheeler
I have the same trouble with my 2006 commander, this just started, it has not done this for the 4 years since I purchased this. I've taken it in for service and both times they tell me that this is normal and to adjust the louvers on the vents. But as beforehand mention. This has not been an issue in the past. It's like the vent is not closing when the blower is off. Anyone - your advice is appreciated. Have you found a solution......Thanks - jonboy65
Vehicles with manual temperature control may develop a condition where warm air is coming from the instrument panel outlets when cold has been selected. Our technicians tell us a revised air dist...
Also when the car stops the air quits blowing cold on the drivers side.
Where should I start to look for the problem?
