Do the simple things first check ur batteries. You have to unhook them and test individually. Sounds like you got a bad starter or ignition switch. You can test the starter turning the key on and touch the 2 post on cylinoid with a screwdriver or jumper wire. If it’s in the switch or solenoid it will start. If it won’t start it ur starter or batteries. Their are 2 fuses in the fuse box. A 30amp and a 5amp sitting together. On a freightliner they sit bottom left corner usually hidden. One of those control ur blower motor. I put a 40amp and 20 amp in mine works fine now. I don’t know why anyone would use a 5 amp fuse but that’s wat will be in there
