My cooling fan will not turn off. 2001 Hyundai Elantra GLS 2.0 l engine

1. Check the scan data for engine temperature to see if it shows that the engine is running hot. The ECM will turn the A/C relay off if it thinks that the engine is overheating. Check engine coolant temp sensor

2. Test voltage at the Powertrain Control Module (PCM) pin 50 (Yellow) and pin 58 Yellow/Black. Both should have battery voltage when the system is turned on and the engine is running. If not, then the wiring needs to be checked.

3. If battery voltage is present on the two pins, then manually ground pin 68 (Orange) at the PCM and this should ground the A/C relay and the clutch should engage.

4. If it does, verify that the PCM powers and grounds and connections are good.
