How does an HVAC Blower Motor Switch work?

Installed either in the engine compartment and against the firewall or underneath the dashboard in the HVAC central housing, the blower motor sits dormant until the blower motor switch is activated by one of the vehicle's occupants. The switch is normally mounted on the instrument panel, and most times there are at least four or five fan speed settings. When the switch is turned to one of these settings, that circuit becomes active, and the blower motor resistor will change the speed of the fan accordingly.

What are the symptoms of a bad HVAC Blower Motor Switch?

This switch fails in one of two ways, and both are easily recognizable. If an issue with the switch causes a short from power to one of the various fan speed settings, the fan will blow in that setting whenever the vehicle is turned on. Additionally, if the contacts inside the switch begin to fail, the fan may not work in at least one setting, or perhaps all settings.

Can I drive with a bad HVAC Blower Motor Switch?

A faulty HVAC in a system is not typically a driveability concern, and normally the vehicle can be driven indefinitely. The comfort and safety of passengers should be considered, especially in temperate zones. In extremely hot or cold climates such as the northeast or southwest United States, blower motor failure in the vehicle could be a risk factor for children and seniors.

How often do HVAC Blower Motor Switches need replacement?

Blower motor switches do fail, but it is impossible to predict the failure. Frequent use of any part will eventually lead to wear and tear, and the switch for the blower motor is one of the most frequently used portion of most vehicles. Also, the location of the switch in relation to the cupholders and sunroof is also a risk factor, as rainwater and spilled beverages are likely to contact the switch.

How are HVAC Blower Motor Switches replaced?

Disassembly will have already been accomplished during testing, so the only procedure needed is to un install the switch from the HVAC control unit, and install the new switch. On some models, this may require replacement of the entire HVAC control unit, or the switch may disconnect by a solitary electrical connector. Once the HVAC control unit of HVAC blower motor switch is replaced, the control unit can be remounted in the instrument panel, and any trim can be replaced.

RepairPal Recommendations for HVAC Blower Motor Switch issues

RepairPal recommends testing of components prior to replacement. Especially in the case of the HVAC blower motor switch where there are multiple components that will cause the same issue, testing can prevent frustration and unnecessary costs.

What to look out for when dealing with HVAC Blower Motor Switch issues

Failure of the HVAC blower motor switch will cause the exact same symptoms of a failed microcontroller (the HVAC control unit), or the blower motor resistor. Diagnosing these three components will be necessary to locate the true problem, and avoid replacing unnecessary parts.

Can I replace the HVAC Blower Motor Switch myself?

Diagnosing the switch should be done by the DIYer with adequate experience with electrical and computerized electrical systems. At the very least, a basic understanding of electrical circuit testing is required. Replacing the switch can be done by nearly anyone so long as care is taken not to damage interior trim and other components during removal and installation.
