I want to share a recent experience with my 2001 4WD Supercrew. One morning I noticed my instrument panel illumination lamps did not come on. I drove to work anyhow. I got out of the truck at work and noticed the headlamps would not turn off. I verified I wasn't in autolamp position of the headlamp switch. I had to remove the 2 low lamp fuses to get the lights to turn off. I found that night the the tail lights did not turn on in either the parking lamp or headlamp position After troubleshooting the problem I found Fuse F6 in the battery junction box was blown. This fuse controls the voltage to parking lights portion of the autolamp module. Replaced the fuse no problem since...
