Keep the HVAC blower and vent circuits switching cleanly with the Four Seasons relay (MPN 35788), an HVAC Blower Motor Relay / HVAC Vent Control Relay that uses a low-current control signal to switch the higher-current circuit feeding the blower and vent controls. It drops in as a direct-fit replacement for many Chrysler, Dodge and Plymouth vehicles, among them the 1974-1976 Dodge Monaco and 1974-1976 Chrysler New Yorker — see the "Vehicles it fits" section for the full list.
- Standard 5-terminal design: five male blade terminals for a secure electrical connection.
- Rated for the circuit: 12-volt operation with a 25-amp amperage rating.
- OE-style molded connectors and quality contacts help ensure proper conductivity.
- Includes a mounting bracket and is engineered for vehicle-specific applications.
If a failed relay is the cause of an inoperative blower or vent function, this replacement takes over the switching job of the original. Signs a relay may need replacing include intermittent or no blower operation and clicking or dead HVAC controls; diagnose the cause before replacing. Backed by Four Seasons and its decades of mobile A/C experience.

Frequently Asked Questions
What does the Four Seasons 35788 relay do?
It is an electrically operated switch that uses a low-current control signal to switch the higher-current circuit for the HVAC blower motor and vent controls on the listed applications.
What are its electrical specifications?
It is a standard 12-volt relay with a 25-amp amperage rating and five male blade terminals, and it is silver in color.
Does it include a mounting bracket?
Yes. This relay ships with a bracket and features OE-style molded connectors with quality contacts for proper conductivity.
Which vehicles does this relay fit?
It fits many Chrysler, Dodge and Plymouth vehicles, among them the 1974-1976 Dodge Monaco and 1974-1976 Chrysler New Yorker. See the "Vehicles it fits" section for the full list.
How do I know if my relay has failed?
Signs a relay may need replacing include intermittent or no blower operation and unresponsive HVAC controls. Diagnose the cause first, since other components can produce the same symptoms.
