Re: Grand Cherokee Lights stay on
This is a known problem with the 2000. The AUTO position and the OFF
position on the headlight switch at the end of the stalk are very close in
signal level. Occasionally the body control computer misinterprets the
signal when the switch is OFF and thinks its in AUTO, turning on the lights
if its dark enough. Usually the lights go off themselves but not always. I
have the same problem on my 2000 though I haven't seen it for a while. I
tried to get the dealer to replace the switch but I'm long past warranty and
I ended up leaving it alone.
