99 Tahoe with Reverse light issue...

[Idlewild9]

I have had this truck since 2006, and have had a wild ghost issue with the reverse lights:

1. They come on perfectly when the prindle switch is in the proper location.

2. They are constantly on from the second I turn the running lights/headlights to the "on" position.

I have wired chased and tried to fault isolate this for hours, and am running out of options. I don't see any crossed wires, dirty grounds, or frayed wires anywhere around the light controls or the tailights themselves...

The only way I have been able to drive it for the last couple years, is by pulling the reverse lightbulbs out.

Please assist!

your best shot (because no one not even myself would know what your prob is) would be to take it the damm dealer or a local GOOD electrical shop and stop struggling for a inspection a shop should charge you like (65$ bucks at the most) and dealer would charge you at least 80$ so best shot if u wanna go cheap is a electrical shop!!!

I agree with Jounier. Mine is the common reverse lights dont like to go on unless I jiggle the shifter while in reverse. It's something to do inside the column around the connections. I heard from a friend of mine that the connections "shift" inside the column so it doesnt allow the connection needed. GOOD mechanical/electrical shops as stated would know what to do to resolve it for you.

Try taking the light assembly out (two screws) then un plug one side at a time and see if this causes the lights to go out if so you have narrowed to which side is the problem then check the bulb as it may be a double filament bulb which should be a single if so replace the bulb if not replace the little circuit board which the bulbs turn in to it's avaiable from most after market suppliers
