Yes there is a fuse
what kind of nest? did something chew through a wire?
could be under dash or the fuse box under the hood if you still have it check the owners manual in the glove box dont jump steps and just replace the fan could be fruitless

Blown fuse perhaps.... but also if this car is equiped with air filters for filtering the circulating air inside the car .. if they become clogged it sends a message to the fan switch and the fans will not runn until the filters are changed. You can uusully find them in the glove box somewhere.
Check also the heater blower relay and replace if necessary (position nr. 6 on fuse box/relay plate). "K28" in circuit diagram code, for car with A/C system. (Fuse F8 (40A) for A/C heater blower motor). The last piece out of order will be the A/C blower motor! In the most cases the carbon brushes are used.
I have not worked on your model of car, sorry. However there should be a fuse and a relay to deliver the power to the motor. Check that the motor is working by puting a live feed to the live side of the motor. If the motor works, trace the wiring back to the next connection and do a connectivaty test with your multi meter, keep tracing the wiring from connection to connection until you find the fault. However if the motor fails to work , then the motor is at fault. If you got yourself a workshop manual from Autodata or Haynes Manuals you will find that the wiring loom has easy to follow diagrams and will save you a lot of time.
check to be sure that nothing has made a nest in your blower motor.. I have found mouse nests, rats nests, and even dead snakes inside the blower motor on these trucks..with all the extra weight inside the blower, the low speeds turn slow and will burn the resistor out quicker.
