International LT Blower Issues

2018 International LT
Intermittent front blower problem.

A few weeks ago blower was not turning on at all. Found the circuit breaker tripped.
After resetting it, everything appeared to function normally.

About 10 days ago we started noticing the blower would stop, start, change speed during normal operation. Heat/AC does not seem to matter.
Also the fan speed frequently does not correspond with the control knob.

Strange as it sounds the blower is frequently running when the truck is not turned on. When this occurs the blower does not respond to control knobs in the front or in the bunk. And blows mainly cold air.

Often the blower will run whenever the Espar heater is on. This is an air heater, it does not integrate with the ducting so it shouldn't do that I expect.

 

Quick addition, Sometimes the blower will not work at all but then starts again after the truck has been off.
