Rear Climate Controls Not Working

[zhala]

The other day I was messing around with the overhead rear climate controls in the front and I noticed there is no change in air pressure or even the sound of changing fan speed for the back. I checked the 30A fuse for the auxiliary blower and it looks fine. Are there any other fuses or maybe ground connections I should check? Thanks.

On my Aviator there is a switch in the front that enables use of the rear controls. Check that that is in the right position. If so, then start by tracing the wires from there?
