    I have no air coming out of the vents. The fuse keeps popping when I turn the ignition on. I would like to find where the blower motor is on my 2022 Peterbilt 520 cabover garbage truck so I can disconnect the power plug and isolate the short. Is it the motor drawing a lot of amps or is it the wire harness?

    Sounds like the blower motor is toasted. Could be a chafed power wire grounding off but I’d suspect the motor first. Not sure where the heater box is in those, but I would think under one of the removable panels on the top of the doghouse would be a good place to start looking.
