Manage how fast your cabin fan runs with the Four Seasons blower motor resistor, part number 20403, a vehicle-specific part that helps regulate the speed of the HVAC blower motor. It fits many vehicles, among them the 2004-2008 Chevrolet Astra and the 2007-2008 Cadillac BLS, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.
Four Seasons lists this part as an HVAC blower motor control module, so you may find it under the name blower motor resistor / blower motor control module. Either way, its job is to help control blower motor speed in response to the settings you choose on the climate controls.
- Vehicle-specific: made for the listed applications.
- Precision engineered: precision engineered by Four Seasons.
- Quality contacts: designed to maintain proper electrical conductivity.
- OE-style connectors: fitted with OE-style connectors for the electrical connection.
If a failed resistor is the reason your blower runs only on certain speeds or not at all, the 20403 replaces it. Diagnose the cause first, because a faulty switch, damaged wiring or a worn blower motor can produce similar symptoms. Four Seasons brings more than 50 years of mobile A/C experience to its products.
