Keep your heating and air conditioning system switching power on command with the Four Seasons HVAC Blower Motor Relay / HVAC System Relay, part number 36163. It is a standard relay that lets a low-current control signal switch power in the HVAC circuit it serves. It fits many vehicles, among them the 2002-2005 Honda Civic, 1998-2002 Honda Accord and 2003-2007 Honda Pilot, and it is a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list and engine details.
Four Seasons brings more than 50 years of mobile A/C experience to this part. The company engineers and tests its products with the goal of long, trouble-free service.
- Precision engineered: built as a standard relay for HVAC blower motor and system circuits.
- OE-style molded connectors: molded connections that follow the original equipment style.
- Quality contacts: help maintain proper conductivity through the switched circuit.
- Vehicle-specific applications: cataloged by year, make and model for the listed vehicles.
When the HVAC controls send their signal, the relay's contacts close and carry current to the load. If a failed relay is the reason your blower or HVAC function won't come on, or works only intermittently, this unit replaces it. The part is listed under two names: HVAC blower motor relay and HVAC system relay.

Frequently Asked Questions
Will this work as a 2002-2005 Honda Civic AC relay?
It is cataloged as an HVAC blower motor relay / HVAC system relay for the 2002-2005 Honda Civic. The "Vehicles it fits" section shows the full fitment chart.
What does an HVAC blower motor relay do?
It is an electrically operated switch. A low-current signal from the HVAC controls energizes it, and its contacts close to carry power to the circuit it serves, such as the blower motor.
What are signs this relay may need replacing?
A blower or HVAC function that won't turn on, works only intermittently or cuts out may be a sign of a failed relay. Fuses, switches and wiring can cause the same symptoms, so diagnose the cause first.
What features does the Four Seasons 36163 have?
It is a standard relay with OE-style molded connectors and quality contacts for proper conductivity. It is precision engineered for vehicle-specific applications.
How is this relay installed?
The vehicle service information gives the relay's location and the replacement steps. The relay uses OE-style molded connectors.
