Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hi. Have you tried turning the dimmer switch for interior lights down? All the way up keeps the lights on.
I know. Have you tried turning the dimmer switch for interior lights down? All the way up keeps the lights on
Ok. The main light switch dimmer switch sends a signal to the interior lamp relay. Sounds like the main headlamp switch may need to be replaced.
The interior lamp relay is built into the instrument cluster.
THe relay is built into the instrument cluster and is not serviceable. And I have in the past replaced instrument clusters to fix this concern. But first check the switch. CLICK HERE for procedure to check switch.
You need to put the meter on ohms and check for continuity in the different switch positions.
You are going to be checking for continuity through terminals using the chart while working the switch.
Ok. DO the lights still stay on if the headlamp switch is unplugged?
The lights should turn off when the headlamp switch is disconnected as you are removing ground from the relay. More than likely you need to replace the instrument cluster. The relay is built into the cluster.
Yes that is correct. The cluster is not the fuse box. There interior relay is just built into it.
I have been a Ford mechanic for 20 years. CLICK HERE for the wiring diagram so you can see for yourself.
From what you explain it sounds it. But a switch would be a lot cheaper than a cluster to try if you are not sure about it.
I am going to have to opt-out and see if another expert has more info on this.
