Usually, all that happens is that you are left with only the high speed setting, no matter what setting you put the switch on. In some cases though, the wiring or harness can be damaged near the resistor and should be replaced or repaired along with replacing the resistor.
What can happen when a blower motor resistor goes bad is that the motor will run and then suddenly stop running on a regular basis. Sometimes the blower fan will not turn on and cause the motor to overheat.
A malfunctioning blower motor resistor will cause the blower motor not to work. When the resistor is bad the blower motors will not turn on.
The a/c heater blower motor resister is located in the vehicle on the passengers side inside the housing next to the blower motor...............Remove the blower motor resistor wire harness connector.Remove the blower motor resistor screws.Remove the blower motor resistor.
Resistor is a separate unit from the blower motor
Generally the blower motor resistor is found close to the blower motor. It relies on the blower motor to keep it cool.
To change the blower resistor on a BMW 740iL, first, disconnect the negative battery terminal to prevent electrical shorts. Remove the glove box for access to the blower motor assembly, then locate the blower resistor, which is typically near the blower motor. Unscrew the resistor, disconnect the electrical connector, and replace it with the new unit. Reassemble the glove box and reconnect the battery to complete the installation.

The 1991 Honda accord blower motor resistor is located on the firewall in the engine compartment. The blower motor resistor will be on the passenger side of the firewall.
The blower motor fan cools the resistor so the resistor is usually located close to the blower.
In general, the blower motor resistor is located close to the blower motor.
