Running lights? or brake light issue
Hello again, my dad has a 1994 f150 and it has a problem with the brake lights, I believe they are called running lights? The lights that are suppose come on in the rear when you turn the headlights on do not comeon unless you turn the headlight switch fully to the left and that activates the dome light. That is the only way you can get the rear lights to come om when you turn the headlights on.
I put a new headlight switch in but that didn't work. I called the Ford dealership and they told me to check behind the steering wheel and that there is a wiring harness there that comes loose sometimes if you use the tilt alot. I checked that and the problem still persist.
The only electrical work that has ever been done that we know of is they guy my dad bought it from stuck a Pioneer cd player in the truck. I oulled it out to check his wiring and it appeared to be correct.
Anyone have any suggestions?

Bump.
I have a similar issue in that when I pull the light switch all the way out, all I get is headlights and nothing else. When I pressit in to half way I get the side markers, tail lights, and the dash lights. I have already replaced the switch and connector and cannot find any complete wiring diagrams for the light switch.
Any help would be appreciated.
This is for an 1990 F150 XLT Lariat/ 4.9L

I have a similar issue on a 1990 F150/ 4.9L. When I pull the light switch all of the way out I only get the head lights. When I push it back in about 1/2 way I get the tail lights, marker lights, and the dash lights. I have replaced the switch and the connector and still no good. Also, I cannot find a wiring diagram that has the complete schematic of the light switch.
Any help would be appreciated.
