Cooling Fan Control Relay (5-Pin)
- Remove relay from engine compartment fuse/relay block. See Figure. Check for continuity between relay terminals No. 1 and 3. If continuity is not present, replace relay. If continuity is present, check for continuity between relay terminals No. 1 and 2. If continuity is not present, go to next step. If continuity is present, replace relay.
- Using jumper wires, apply battery voltage to terminal No. 4 and ground to terminal No. 5. See Figure. Check for continuity between relay terminals No. 1 and 2. If continuity is not present, replace relay. If continuity is present, inspect associated wiring for short or open circuits. See WIRING DIAGRAMS article. Repair wiring as necessary.
