Where is the blower motor located on a car?
Your blower motor is typically located on the passenger side of the vehicle under the dash. Check for melting on the blower motor resistor or its plug. If they don’t appear to be damaged, the blower motor itself may need to be replaced. If the blower motor, resistor, or plug need to be replaced, O’Reilly Auto Parts has the parts you need.
What happens when a blower motor resistor goes bad?
Since the part gets hot and draws a lot of power from the electrical system, a failed blower resistor may also melt part of the wiring harness when it fails. When a blower motor starts to go bad, it can draw more power than the resistor is rated for and cause it to fail.
What’s the highest speed a blower motor can go?
On most vehicles, the highest blower motor speed setting bypasses the blower motor resistor to give the fan full vehicle voltage (typically between 12 and 14.4 volts). If the blower motor still works on high, but will not work on any other speed, it usually points to a bad blower motor…
It is usually in the passenger-side footwell area, below the glove box. Vehicles built before the mid-late 1990s often have the blower motor located in the engine bay on the passenger side firewall, in plain sight. Remove lower trim panel below the glove box.
What happens when you change the fuse on a heater blower?

If the blower works when you change the fuse, you may not be out of the woods yet. When the motor gets old and tired it will draw more current through the wires than a new motor.
When to replace a heater blower motor switch or relay?
When the motor gets old and tired it will draw more current through the wires than a new motor. It may still draw enough current to blow the fuse after it runs for a while. In that case, a motor replacement is in order. Step 1: Disconnect the battery. Put on your safety glasses and disconnect the battery at the negative cable.
Where can I find the heater switch on my car?
The older your car is, the easier this job will be. Most of the time, the switch is accessed from the back of the dash panel and can only be reached by removing a few pieces of trim. Cardboard panels held on by plastic pins or screws cover the bottom of the dashboard and are easily removed.
