The overhead trip computer in my 2001 F250 7.3 works, but it is very dim. You cannot see the display in the daytime, only at night, and then it is extremely dim. Even with the instrument light thumb wheel dialed all the way up. It also appears that the instrument cluster lighting could be brighter also. Has anyone else experienced this problem? Also, my cruise isn't working, nor the power mirrors. I mention these other two problems for the remote chance that they could be all related. Thanks for any insight. Kevin Holder.
