Answer -
It is usually located near the blower motor.

EXACTLY what is the problem with the blower motor, Does it not work at ALL ?.
the blower was working fine, but one day going down the road it quit, now it just clicks on all speed settings and will not blow.

Answer
Did you try using a 20 amp fused jumper wire from the battery positive terminal to the blower motor feed wire to see IF the blower motor works ?.

I don't have a truck electrical book so I can't be SURE where the realy is located. It is usually mounted near the blower motor.

Purchase a NEW relay and this will show you what you are looking for.
