the blower motor is located on the passenger side firewall under the hood remove 3 or 4 bolts and the motor will come loose
On the Dodge Ram truck, the heater fuse for the blower is on the fuse panel on top of the battery. There is also a blower motor resistor on the blower motor. The fuse to control the heat control panel is in the fuse box in the dash.
RIGHT BESIDE THE BLOWER MOTOR UNDER PASSENGER SIDE OF DASH
they are usually found close to the blower motor.
The resistor motor may have went out if the heater blower quit working on a 2004 F-250 Truck. The cost to replace the motor is approximately $200.
how do I change the heater blower on a f350 2002
by the blower motor there is a resistor connection, you will find it melted the blower motor is bad. it draws to much power causing the connection to get hot and melt and burn. you will have to change the connector and the blower motor. the blower is still working but its drawing to much power, the motor windings are shorted out inside. disconnect the connector from the resistor and you will see it.
In the HVAC compartment attached to the firewall on the right side of the vehicle.
I would check any fuses/relays related to the heater or blower motor. If the heater fan doesn't work, could be a bad heater blower motor resistor(if has one) which are usually inline in the ductwork or out next to the heater blower motor under the hood. If the fan does work w/no heat then could possibly be a bad thermostat(stuck open) or control head.
Only for the high speed blower function. The lower speeds go thru the blower motor speed resister.
You may have a vacuum leak
The blower motor is up under the dash on the passenger side of the inside of the truck. I had to replace mine when it was approximately 1 or 2 yrs. old.
Its should be behind the glove box.. held in by 1 screw
