I have a 2004.5 Ram and yesterday the low beam headlights and the left high beam did not come on. Im thinking it is the FCM or the IPM from what I have read. I am going to start trouble shooting tonight beginning with the fuses and then the ipm to make sure everything has power. There is no way to check the FCM correct it is a process of elimination from what I have seen. Any other things to look for?
