What would cause my blower motor on my truck to slow down while driving If you tap on it it usually comes back to full speed but then gradually slows down?

The blower motor is tired. It will eventually blow a fuse and/or burn out the blower motor speed resistor. Time to replace the blower motor. Also check connections for high resistance damage (melted connections).

Possibly. A bad blower motor resistor would cause the blower motor to either not function or function only on one speed (usually high speed).

most likely cause is one of three relays for the blower motor, usually located on the firewall under a plastic covering or near the battery If you do not use the blower motor very often like your car sits for a few weeks mositure gets in the blower motor and causes rusting which can cause your blower motor to lock up.
