Question about 2003 Jeep Grand Cherokee
Shut off the engine on my 2003 Jeep Cherokee, went in to eat breakfast with my family. Came out and the battery was dead. Looked under the hood and saw that the fan was still running. What would cause that to happen.
It is normal for the fan to run when engine is off. Engine temps actually rise when the engine is shut off, the heat will rise through the engine compartment. So a Coolant temp sensor controls when the fan shuts on and off, obviously based on the temps of the anti-freeze. The fans are a high draw item, but It would take much longer than an hour breakfast for the battery to run dead. I would check out the battery and charging system first. Is the CEL on? Let me know and we will trouble shoot from there. Thank you for using fixya.com
