Hello I will help you with your question,
There is a blower fuse #42 in the integrated power module (fuse block) up front in the engine compartment.
The legend should be in the cover for the box.
Let me know if you have further questions
Do all the controls work on the dash?
The blower speed control often fails so that would be the place to check for power. Do you have a testlight or voltmeter?
Ok, behind the glove box check the dark blue wire for power on the power module connector. The procedure below shows a blower resistor but it is in the same location

Let me know what you find
The plug behind the heater /AC has no juice ..and the power locks won't work either ...is there another fuse box ?
Try removing the negative battery cable for 30 seconds then reconnecting. This will clear any stored codes and allow the computers to reset.
The AC controls (a computer) sends a request to the IPM (fuse block, another computer) to turn on the blower relay when you switch it on. If the fuse block sees something that would prevent safe operation of the blower such as a short it will set a code and not turn the relay on.
If you can reset it by clearing the codes you will need a shop with a DRB3 scantool to pull the codes and then it may need to be reprogrammed or repaired.
Let me know if clearing it restores operation.
