I dont know what these other guys are saying..I think they snif the glue!!! YOUR BLOWER FAN ASSEMBLY CAN EASILY BE REMOVED !!
1. Remove the wire
2.Find the "tab on the housing and pull it down while rotating the fan housing counter clockwise. This will remove the fan assembly. Plage 12 volts on the contacts to test the motor. If it works then the resister pack is blown. On the fan housing (near firewall ) you will see a plug going into a square looking box with a screw in it. Remove the wire then remove the screw to remove the resistor pack.. A new resistor pack is around 20 dollars at a ford dealer. Hope thie "FREE" info helps!
