F41 Error Code

Asked by Dustin Sep 13, 2017 at 07:30 PM about the 1987 Cadillac DeVille Sedan FWD

Question type: Maintenance & Repair

I am receiving a F41 error code and the
coolant/fan light comes on. I have replaced both
radiator fan motors, the bcm, and the radiator
fan control module. I am still getting the error
code. Any help is appreciated!

I had gotten a bad control module. I swapped it out for a different one and the problem went away. It was the body control module that is behind the glove box.
