My van is a B150. Both front and rear AC stopped blowing at the same time. I changed the fuse and it did not resolve it. Is there a blower motor for both units? If so would the fact that both units stopped blowing simultaneously be an indicator that it is not motor related?

It looks like they share fuse #15 20 amp I would start by checking that first.

Here are some guides and diagrams so you can do some testing so we can get it fixed:

Thanks Ken

I tested all of the fuses and they all check out. The user manual does not show the location of the AC relay and doesn't show where the PDC is. I will keep investigating and keep you posted.

I have the location of the air conditioner relay and the PDC (below)

Please let us know what you find. I'm interested to see what it is.

Cheers, Ken
