Am new to this site. Own a '98 F150 ext cab. Had a taillight burn out today and since replacing it, my dome light and exterior back-up light have stayed on continuously. Anyone have any ideas? I checked all the doors, tailgate, lighting control switches and *****. Should I just pull the fuse on these two lights until I can get it into the shop?
Since you said you have checked all the switches that leaves out my thought of the headlight **** for the dome light or switch on the dome light itself. Could be a stuck door switch. Backup light is off the switch for reverse so this may be stuck or misadjusted.
Yes, I checked the interior dome control and have checked all three doors. My "Door Ajar" warning light has also been on even after rechecking all the doors and slamming them real good. Would installing the wrong flasher bulb in the rear tailgate area cause this? I took out a 3457K bulb, but AutoZone gave me (and I looked it up) a 3157LL. Any ideas?

I had this problem when I got my 98F150, the solution was so spray WD-40 into the locking mechanism to free up some junk on the contacts. Has worked fine ever since (9 months and counting)
