Buying advice

When buying a heater relay, check your vehicle's specific relay type (e.g., 4-pin or 5-pin) and amperage rating. OEM or branded relays often provide better reliability. Ensure the relay fits the socket; some universal relays require adapters. Read reviews for compatibility with your car model.
