Set how hard your cabin fan blows with the Standard Ignition A/C and Heater Blower Motor Switch, part number HS-275. This is the switch you use to tell the blower motor how much air to push through the heating and A/C system. It fits many vehicles, including the 2005-2010 Chevrolet Cobalt, the 2007-2009 Pontiac G5 and the 2000-2003 Chevrolet Monte Carlo. It is a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
This part is listed as both an HVAC blower motor switch and a window defroster switch. It comes from a global manufacturer of original equipment ignition products, which maintains quality control throughout manufacturing, from the components to the finished product.
Signs this switch may need replacing: the blower runs on some settings but not others, the fan doesn't respond when you move the switch, or the fan cuts in and out. A blower resistor, blower motor or wiring fault can cause similar symptoms, so diagnose the cause before replacing the switch.

Is this the right 2007-2009 Pontiac G5 switch for the heater and A/C blower?
Yes. HS-275 is a direct-fit replacement blower motor switch for the 2007-2009 Pontiac G5.
Can I use this as a 2005-2010 Chevrolet Cobalt switch too?
Yes. It's listed for the 2005-2010 Chevrolet Cobalt and the 2000-2003 Chevrolet Monte Carlo, along with many other vehicles. The Buyer's Guide tab has the full list.
What does a blower motor switch do?
It's the control you use to choose the blower motor's fan setting. That setting decides how much air the heating and A/C system moves through the cabin vents.
How is the HS-275 built and tested?
It uses copper alloy conductors for strong electrical conductivity with low resistive losses. Standard tests 100% of these switches for mechanical and electrical switching performance.
What are signs the blower motor switch may be failing?
The fan may work on only some settings, ignore the switch, or cut in and out. A bad resistor, motor or wiring can cause similar symptoms, so diagnose the cause before replacing the switch.
