I just bought a 2002 Town & Country and found out no air comes out from the rear a/c outlets at all. It is a three zone climate control. The front side works perfectly. I checked the rear blower fuse. It is OK. I swapped the front blower relay and rear blower relay. The cold air comes out from the front a/c outlets but no air out from the rear outlet again. It seems the blower is not working. What should i try next? The rear blower power module or the blower motor? It will be a big job to access these components. Any input is appreciated. Thanks.

are u trying to use the rear controls orthe ones up front?

 

I tried to set front setting to auto then change the temperature. Also I tried to set front setting to rear control and turned the rear control **** different postions. Neither way worked.

 

u might be looking at a rear blower motor power module.

 

Thanks for the suggestion. I have to remove the right quarter trim inner panel to access the rear power module, right? Do I need a special tool to pry the plastic panel out (to disengage the hidden clips)? What other tools do I need to complete this job. Thanks a lot.

 

I use a trim clip remover but u can use a screw driver and just reattach them back to the panel once removed.

 

but with the heat.

When I use A/C up front, the rear vent operate to recirculate the car air. When I switch the front control to heat (with a/c button lit/on) air flow from the rear vents stop.

Thanks a lot.

 

A update: The problem was solved by replacing the rear blower motor power module ($65.50 part#04885482AA). Now the cool air comes out from the rear a/c outlets.
Thanks for the help.

 

The reason why no heat is coming from the top vents is because when heat is selected for the rear they come out of the bottom vents and use the principle of heat rising. Anyway that is why you do not get heat from the top vents.
