The problem exists somewhere in the circuit for the HVAC blower. Check fuses and relays. If they check out, check for power and ground at the weatherpack terminal which connects to the HVAC blower. If that checks out, then your blower motor is probably bad.
there is a short somewhere in dash or heater, you need to fix that to stop fuses blowing
There could be multiple reasons why a heater would stop working in a truck. There could be low coolant or a bad fuse to make a heater stop working in a truck. The best way to find out the reason is to take it to a certified auto mechanic.
Sounds like heater core is leaking, replace heater core or bypass
Not with the clutch by itself.
Fuse, switch, speed resistor or motor.
Turn it off.
no
Defective blower motor? See if it is sgetting power Blown fuse?
it means to stop blowing in his ear
You ONLY use the clutch brake when you're at a complete stop.
You stop blowing up the world.
Well the more correct term would be 'semi Trailer-Truck' or something to that capacity. It means that it is both a large truck and partial trailer in the sense that it has the capacity of a large hauling truck and a small living quarter for a person travelling to rest in when they are stopped at a truck stop. Such Trucks are meant for carrying large quantities of cargo long distances by road and allowing for the driver to rest from time to time.
