    It may very well be related. You need to let your shop know about it.

    There is an issue with the fan solenoid. Fmi 4 is low voltage or short. Follow the fan airline from fan and you will find solenoid. Without starting the engine turn the key on and you should hear the solenoid click then release when you turn the key off. If it doesn't then either the solenoid is bad or there is a wiring issue going to the solenoid. A test light will help greatly
