09 town & county
212,000 miles
3.8 motor
My rear heater control isn’t working
I replaced the whole unit and still don’t work
Can someone tell me where the relay fuse is located ?
It worked for a minute then stopped I’m thinking it could be a bad fuse or relay
Thanks

What specifically isn't working?
Does it work from the front control?

The front controls work fine, if the rear control that don’t work, blower motor isn’t working on any setting

Maybe you didn't understand my question.
Can you control the rear blower from the front control?

The rear control uses it's own module and sounds like where the problem is. The switch is built into it.

Is there a separate fuse or relay for it ?
How do I go about fixing it ?
I replaced the whole unit with another one and it worked for a minute, then stopped
The whole heater controls, front and back sre on the same unit

Yes, there is a relay and a fuse in the main power module under the hood.
Here is the wiring diagram
