I have an 05 Excursion with climate control. It is suffering from the blower always on high condition. The dealer sold me the resistor pack and says that is the fix. Do the EATC vehicles have a resistor pack? If so, where is it?

 

Raise your hood. Look at Rh back firewall. (passenger side)
You can see the rear of blower motor.
Look beside it there is a plug (I believe to the bottom right)
The small rectangle assembly under that plug is your resistor block.
Remove the 2 bolts that hold it to the firewall and pull it out.
Reverse proceedure to reinstall.
Then you will be cooking -w- heat again

 

Thanks for sharing info.
