good morning, and happy holidays.

i went out to gather some things for the holidays. when in the middle of my trip the heater blower quit working. well i switched all the speeds and vent possision switches, but nothing, it just quit. so i finshed up my shopping, having to clear the ice and fog inside the truck from the cold with a scraper and t shift i had. no fun at all. Get home and still nothing. I ve used the search function and searched the web, to no avail.

I'm not sure what to check, i removed the cd player to get access to the heater controlls, un/repluged them no help. checked for power with key on, nothing on the speed side. I also took the heater pannel from my crown vic to try and still nothing, so its not a switch problem. Its like it not getting power to the blower. I ran a set of wires from the battary becuase i want to manualy put power to the blower to make sure is runs. it doesn matter if a do not have speeds of not, as long as the windsheild is clear for winter. But i do not know where to put these wires to do this. any help at all would be great. thanks jon

 

Sounds like the blower motor resistor is shot. It is located under the dash, on the right side, mounted to the heater/AC box. Should be about $40.00 to replace yourself.

 

okay, i did some reasearching about the resistor. didnt take it out yet, way to cold, -30 with windchill here. i ran some new wires from the battary to pluged them into the orange and brown wires, (which i think is positive and ground) directly to give the motor 12v. And nothing happened, i reversed the wire in case. but no luck. I did unplug the resistor as well and it looks like it shorted out, there is black in the inside of the plug on the black wire. which i assume is ground. any help.... as it would be nice to use my truck agian... cheers.
