Now that cold weather is here, I've noticed that the rear passenger heater on my 2006 Pacifica is not working. The front heater, A/C, fans all work fine, its just the vent for the back seat doesn't work. The fan doesn't work but it feels like there is a tiny bit of cold air flowing out. I've seen some other posts about the blower module or resistor behind the glove box but that seems to cause problems with the main heater/fans in the driver and passenger vents, not the rear. I've checked all of the fuses. Any ideas would be appreciated.

 

ok lets see if u can clear things up first do u have a hot/cold air issue in the back or do u not have any air flow from the back? Both are not related to each other so need to know which issue it is.

 

I guess the main problem is that there is no air flow

 

check the blower motor and or the resistor for the back then

 

Is there a separate blower motor for the back? If so, where is it located? I know the main one is behind the glove box.

 

oblivious there is a second one in the back u have a separate control for it right? ever heard of a fan running at 2 different speeds at the same time?
