Help keep your heater and A/C blower switching on command with the Four Seasons HVAC Blower Motor Relay 35925, a standard relay also listed as an HVAC relay and a temperature control relay. It is a direct-fit replacement for the listed applications and fits many vehicles, among them the 1975-1982 Ford F150 and the 1975-1982 Ford F250. See the "Vehicles it fits" section for the full list and engine details.
A relay lets a low-current control circuit switch a higher-current circuit on and off. If a failed relay is the cause of a blower that won't run, runs only some of the time, or won't shut off, this unit replaces it.
- Precision engineered: Four Seasons engineers and tests its products for trouble-free operation, drawing on more than 50 years of mobile A/C experience.
- Molded connectors: OE-style molded connector design.
- Quality contacts: Help maintain proper electrical conductivity through the relay.
- Vehicle-specific applications: Built for the specific vehicles it is listed for.
It is backed by Four Seasons' "fix it once, fix it right" approach.

What does an HVAC blower motor relay do?
It lets a low-current control circuit switch a higher-current HVAC circuit, such as the blower motor circuit, on and off.
What are signs this relay may need replacing?
Possible signs are a blower that won't run, works only some of the time, or keeps running when switched off. Diagnose the circuit first, because other HVAC components or the wiring can cause the same symptoms.
What features does the 35925 relay have?
It is precision engineered, with OE-style molded connectors and quality contacts for proper conductivity. It is built for vehicle-specific applications.
