I've got a unique one.
Following some advice here or another forum it seemed pretty obvious that my stock 4x4cm had failed. I purchased a used one (2C54-7H473-BF) recommended for the fix. It seemed that all the connectors and everything are the same and it should be a direct swap. But when I installed the new CM the heat/AC vent just started blowing full blast. I put the keys in, started the truck up, and didn't get any reaction from the 4x4 selector switch. Now, WTF with the 4x4 module could effect the heater vent? Does anyone have any idea what the deal is here?
