My 2005 Ford F350 Superduty has the automatic temperature control system. Today when I started the truck, the ATCM module in the dash had no lights or power come on, and no air blows at all. I've been figuring that it is a fuse gone somewhere, but cannot seem to find it. Any Ideas?

Sounds like you have an issue with the climate module. Basically, we need to start with checking power at the module and find out what is there.

It could be a fuse so we need to check all that go to the module, but I suspect we have a module failure.

So, let's start with this and go from there.
