Blowing a fuse is a clear indicator that the current being drawn is exceeding the rating of the fuse that is designed to protect the circuit. The first item to check is the rating of the fuse and ensure that it is not under specification.
Then check to see if any additional accessories which have been installed have been added to that circuit if yes it may be necessary to increase the capacity of the fuse. If nothing new has been added to the circuit then the next item to check is for short circuits ie grounding of power wires through chaffing of the harness or through crush damage to the harness usually the result of a collision and repairs not identifying that the harness that passes through the damaged area is also damaged. Another are to check is if accessories have been added to the vehicle sometimes the mounting screws can be piercing the harness, try removing the mounting screws for the latest accessory to test this. Lastly it may well be that a short circuit in the PCB (printed circuit board) may be allowing higher than designed current flow in which case u need new PCB.

The fan motor is down on the pass side. follow the 2 wires that come off the motor to the heater fan resistor. If you can unplug that it. Most likely the connector will be burnt and so will the resistor. Replace connector and resistor.

Look at the color and Number on it If both fuses have the same amp rating you can swap them to test. If they are different amps you could just blow the fuse again if its a lower amp rating, or damage your Climate Control system if the fuse has a higher amp rating than the original. By the way, all the GM vehicles I've owned had several spare fuses in side the fuse panel.
