Thanks for the advice Bobflood. I sprayed the switch and any crevices/opening very well with electrical contact cleaner and slid the switch several times to help clean any crud but it didn't help. I noticed that the switch doesn't stay in the off position when I slide it to off, it slides a bit to the right as soon as I let go and the green indicator light illuminates. I suspect the switch is shot. Can it be replaced or do I need a new rear view mirror? (My mirror has the auto head lamp feature and there a temp & compass in the overhead console above the mirror).
Also, before I do anything with the mirror assembly, my search on the internet seems to tell me that if the headlights, rear tail lights, console and parking lamps do not illuminate when the auto head-lamp feature is activated, it's unlikely that the associated relays are the problem since all of them would have to be defective for nothing to work.
Can anyone confirm that several independent relays are involved with the auto-headlamp feature? If that's the way it works then the central problem may in fact be the switch on the mirror, or if there is one feed wire coming from the switch and feeding all the relays, then maybe that wire id damaged. If the switch or the feed wire is shot nothing will work downstream.
Does anyone have a schematic for a 98 5.0 XLT Explorer?
I can do without the auto lamp feature but if I can repair it for a few bucks and a bit of time then why not? Thanks!
