Where is the heater fan relay located on a 1995 Chev Silverado 4x4 ext cab pick-up?

The heater fan relay location on a 1995 Chevy Silverado 4x4 extended cab is under the dash, usually on the driver's side. However, there's no single definitive location as it can vary slightly depending on the specific trim level and options.

To find it, you'll likely need to:

1. Remove the lower dash panel: This usually involves removing some screws and possibly some trim pieces. Consult a repair manual specific to your year and model Silverado for the exact procedure.

2. Look for a relay box or fuse block: The relay will often be in a fuse block or a separate relay box mounted near the HVAC blower motor.

3. Identify the relay: The relay itself may be marked, or you can consult your owner's manual or a wiring diagram to determine which relay controls the blower motor. The diagram will show the relay's location and may indicate its amperage rating.

Important Note: Without a wiring diagram or repair manual specific to your 1995 Chevy Silverado 4x4 extended cab, pinpointing the exact location will be difficult. Using a wiring diagram is highly recommended to avoid damaging other components. You can find these diagrams online (some are free, others require a purchase) or at an auto parts store. A Haynes or Chilton repair manual for your truck would also be very helpful.
