Should a blower motor resistor get hot?
Many blower motor resistors are designed such that they would burn up if they are not in the path of the air from the blower fan. They are that close to tolerance. Not because manufacturers like to burn stuff up but higher wattage resistors get very big and very expensive..... even those will get hot. via
How do I know if my blower motor resistor is bad?
Can a blower motor resistor be intermittent?
When the resister of the blower motor starts to fail, the motor operates only intermittently. The higher current can make the jump across the resistor contacts that are going bad and get the blower motor to engage. via
Can you fix a blower motor resistor?
The resistor module is easy and inexpensive to replace. It's then typically installed in the ductwork, near the car blower—either under the dash or under the hood. (Refer to a service manual to locate yours.) Purchase a new resistor module at the auto parts store (usually less than $25). via
What happens when blower motor resistor goes bad?
If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed. The heating and air conditioning systems may still function at one speed, however the resistor will have to be replaced in order for full functionality to be restored. via

5 Signs Your Blower Motor Needs to Be Replaced
How much does it cost to replace a blower motor resistor?
The average cost for a Blower Motor Resistor Replacement is between $108 and $137 but can vary from car to car. via
How do you troubleshoot a blower motor? (video)
How do you test a blower motor? (video)
How do you test a blower motor resistor?
Place one lead of the Ohmmeter on terminal 1 of the resistor. Place the other lead on terminal 2 and check against specifications. If this circuit is open, showing infinity on the Ohmmeter, the blower resistor must be replaced. Move the lead from terminal 2 to terminal 3 and check this reading against specifications. via
How much does it cost to replace a blower motor?
Cost to Replace Central or Forced Air Blower Motor
Replacing a blower motor costs $450 on average with a typical range of $250 to $800. With a warranty, you might pay as little as $150 for labor alone. For high-end models, like those with large motors or access issues, you might pay as much as $2,000. via
What makes a blower motor go bad?
The blower motor may seem to be to blame when air flow becomes notably decreased, when if fact, the fault lies elsewhere. Insufficient flow at all blower speeds might be caused by a clogged air intake screen. Leaves, or other debris that obstruct the screen can make the blower motor efforts seem feeble, at best. via
How long does it take to replace a blower motor resistor?
takes about 45 minutes. via
