Heater/AC

Our rear heater and AC isn't working in our 89 Aerostar. Our front heater and AC works just right. Does anyone know what could be wrong?

Thanks!

First, what do you meant by doesn't work? The fan doesn't blow, it only blows cold, or it only blows hot. Does it only blow out of the top vents or only the bottom?

Does the fan work with the front switch or the back, or neither.

Please give more info.

There is nothing coming out of any vents in the back. The heater and A/C in the front works great.

Not sure what other information to give you. Let me know what other information you want to know.

Thanks

This sounds like a problem someone else had. Here is the link to that thread.

Read it over and see if it makes sence to you. Having a wiring diagram is a great help. I was using the one in my Haynes manual. You might have to look at the wiring behind the driver's seat in the side wall.
