Hi,

I have been having a problem with the radiator fans not shutting of and causing the battery to drain and go dead. I hooked up a code reader and stated we had a problem with the radiator fan control relay circuit (error code: P1491). We went and put in the radiator fan control relay and then hooked up the battery and it keeps running and did not fix the problem. I was wondering if anyone had any ideas on what I could try next. The engine size is a 3.8 L.

Thanks,
Brian

 

Relay or temperature switch....
