How will a mechanic replace my blower motor switch?

The good news is that replacing the switch is a fairly simple swap. If you’re getting your car serviced, the mechanic will already have disassembled part of the HVAC system in order to diagnose the faulty switch. To complete the replacement, here are the steps they’ll take:

Disconnect the battery: The mechanic will put on safety glasses and disconnect the car’s battery at the negative cable as a safety precaution.

Remove the knob: Usually, the mechanic can simply pull off the knob, but there are sometimes screws they’ll have to remove first.

Disconnect the blower motor switch: At this point, the mechanic can access the switch by removing some of the trim.

Remove the bad switch: The mechanic will pinch the tabs holding the switch’s wires in place in order to pull out the old switch.

Install a new blower motor switch: Next, they will push the wire component of the switch into the empty slot.

Reattach the trim panel and test the system: The mechanic finishes by reassembling the trim and pushing the knob back. They’ll test the system by reconnecting the battery and running the motor.

Note that if your car has a fully automatic climate control system, the mechanic might need to replace the whole control unit instead of the single switch.

What happens if I don’t replace my blower motor switch?

You can keep driving without a working HVAC system, but it can be uncomfortable and possibly dangerous. Not only will you not be able to use the AC, but the heating system might not work when it’s cold out. Plus, you may not be able to defrost your car’s windows if they fog up.

What is a blower motor switch?

The blower motor switch is a switch that lets you control your car’s HVAC (heating, ventilation, and air conditioning) system. Here’s how it works. The blower motor forces hot or cold air from the heater core or air conditioning into the passenger cabin.

You control the temperature and airflow by adjusting the blower motor switch. Most switches are labeled with numbers and symbols so that you can set a comfortable temperature inside the cabin.

How do I know if my blower motor switch is bad?

If the heating and cooling in your car act up, even a little, there’s probably something wrong. Here are the most common signs of a bad blower motor switch:

The heating or air conditioning doesn’t work

The heating or AC works sometimes, but not always

The switch only works on certain settings

The switch is stuck on one setting

The switch is cracked or broken

Keep in mind: Sometimes, it’s obvious that the switch is bad, while other times, a mechanic will need to inspect the HVAC system to determine if the switch needs to be replaced.

How often should a blower motor switch be replaced?

In theory, the switch should last the vehicle’s lifetime. But, the switches are used so much that they frequently wear out. Plan on replacing a blower motor switch when it starts performing erratically.

Keep in mind that the blower motor switch is not inspected as part of a routine maintenance checkup. If you think the switch is bad, make an appointment to get it inspected.

Can I replace my blower motor switch myself?

This is a job best left to the professionals unless you have extensive DIY skills in electrical and computerized systems. It’s essential that a technician makes the diagnosis so you don’t damage the car’s circuitry (or break off your dashboard’s trim when replacing the part).

FAQs

What causes a blower motor switch to fail?
