Interior lights My interior lights flicker on when I turn to the right. I believe I have a loose wire. Where should I start to find it?

Your door post maybe loose and now the ground is breaking causing the light to come on/off from vibration check all 4 door post for tightness and proper closure of the doors easy check out the windows down and push/pull on the doors while observing the interior light for the flickering also there are wires that plug into all 4 door locks inside the door at the latching mechanisms one of them maybe loose on the lock or the wire maybe breaking or a corroded plug connection in one of the doors those are the causes of this problem and are listed in ease of repairs first ok good luck Stephen

You can try pushing the override button located right under headlight dial.

Interior lights generally work to an earth, sounds like you have a trapped wire that's shorting to earth, start with the wiring to the door switches and work your way to the light

check all your grounds i no someone had similar problems and it worked for him

I would check your fuse board for a loose fuse or wire to it from the battery as sometimes vibration loosens terminals eric

I remember having a slightly older GMC Jimmy doing this every once in a while. I was young at that point, but I believe that there are a few of the interior wires that run very close under the carpet, and sitting on the seat mashes the wires to the ground, after a while, it rubs the insulation off, and allows it to short circuit back to the battery.

I would replace the light switch, but first I would have a confederate
go around and jiggle all the door jamb switches while I observed the dash lights. Something is loose, often the brightness control for the dash lights is the culprit.

CHECK ALL FOUR DOOR LIGHT PRESS IN SWITCHES FOR A LOOSE WIRE OR BROKEN.

locate the head lights fuses and check,it may be loose

Definately an electrical problem....first off, check the battery and alternator connections to make sure they are tight. The problem has to be before the fuse box because the headlights and interior lights are on different fuses. It sounds to me like a loose wire, corroded battery terminals, or an alternator that is going bad. An alternator is a relatively easy and cheap fix. They cost about $100 and require removing a few wires, 3 bolts, and the serpentine belt.
