Electric Cooling Fan Control
NOTE:
For electric cooling fan circuit testing, see AIR CONDITIONING & HEAT section. See wiring diagram in WIRING DIAGRAMS
article for terminal and wire color identification.
All FWD and some RWD vehicles use an electric cooling fan. The electric cooling fan is used for radiator and A/C condenser cooling. Cooling fan operates when A/C is on and when engine coolant temperature exceeds a specific value. One or more cooling fan relays may be used. For cooling fan relay location, see COOLING FAN RELAY LOCATION table.
COOLING FAN RELAY LOCATION
| Application | Location |
|---|---|
| "E" & "K" Bodies | Mounted On Lower Radiator Support |
To help save diagnostic time, ALWAYS check for blown fuses or fusible links before proceeding with any testing. If fuses are blown, locate and repair short circuit before replacing fuses. Ensure all related relay and wire harness connections are clean and tight. Repair as necessary. For component location and terminal and wire color identification, see wiring diagram in WIRING DIAGRAMS article.
WARNING:
Vehicles may be equipped with a PCM using an Electrically Erasable Programmable Read Only Memory (EEPROM). When replacing PCM, the new PCM must be programmed.
