    this is a random issue. the dash lights and radio lights/climate control lights all seem to turn off randomly when driving. it seems to happen only at night, when the headlights are turned on. if i play with the light switch they will flicker on and off but aren't really staying.

    also, at night, the interior lights won't stay on when i open the doors. (when head lights on) but after they turn off, if i use the key fob to unlock the door the interiors work fine.

    just wondering if anyone is having such gremlins. i'm thinking i might replace the battery anyways as its 7 years old but i don't think this is the issue. truck also runs just fine regardless of the lights being on or off, and it will still shift into 4wd as well (donno if that would be related)

    all help appreciated thanks!

    If you play with the switch and they flicker, then I would guess that the switch is bad.

    That fits with my way of thinking, too -- i.e. something switch related. Maybe it's the switch. Maybe it's a loose connection to the switch. Maybe it's a wire connected to it that has a short only when it's in a certain position and jiggling it moves it from that position. You get the idea...

    The light bulb is burned out in the one in my 2000 silverado so I am going to replace it. I was looking at an led conversion for it as people have done it. The part isn''t that bad price wise for a new one though:


    I am sure it is $200 from the dealer:)

    The bulb in mine is some strange mini bulb that I can put a 5mm LED and appropriate resister in to replace the bulb. But if the switch is not working, the replacement is the best bet.

    Batteries don't like extreme temperature changes....... really cold, really hot. so anywhere in Canada would get really cold winters; 7 years is a long time for a battery up there.

    I got 7 years out of my last battery but the temperature does not swing quite as much in the extremes in North Carolina as it would up there.

    It would be smart to replace it sooner than when you are stuck on the road somewhere at this point.
