Detailed Description
Standard Ignition RY-347 is an HVAC relay used to switch blower motor power in the climate control circuit. In Audi 4000 and Audi 4000 Quattro applications, as well as Audi Coupe, Audi Quattro, and Audi 5000 Quattro models, this relay helps manage electrical flow to the blower motor through a 12-volt system. The square connector and blade-terminal layout support direct electrical interface in the original HVAC relay location. If you are replacing a failing blower motor relay on a 1980-1987 Audi 4000 or related fitment, RY-347 provides the specified relay configuration for the application.
What It Helps Fix
- Blower motor that does not turn on
- Intermittent HVAC fan operation
- Loss of power to the climate control blower circuit
- Relay-related clicking or electrical switching faults
- Heating and air conditioning airflow issues caused by relay failure
Installation Notes and Tips
Verify the connector shape, terminal count, and terminal type before installation. Confirm the vehicle uses a 12-volt HVAC relay circuit and compare the existing relay to part number RY-347 for match-up. Inspect the relay socket and terminals for heat damage, corrosion, or looseness before installing the replacement. Because this relay is not continuous duty, use it in the specified blower motor control application only.
Quality Assurance
Standard Ignition is a recognized aftermarket brand for electrical and ignition components. RY-347 is built to the listed electrical and connector specifications for the stated Audi fitments, including Audi 4000, Audi 4000 Quattro, Audi Coupe, Audi Quattro, and Audi 5000 Quattro applications.
