1998 Cherokee XJ.. electrical/headlights ?

Hey all,

Another issue popped up. The headlights work fine, both high and low. But
unless you push the switch in to turn off the headlights before I turn the
Jeep off, the lights won't go out. If I turn the Jeep off (ignition
off/engine stops) before I push the switch in the lights will not go out. I
have to turn the ignition key to start, then push in the switch and the
lights will go out. Anyone run across this? Ideas as to what to start
tracing down? No other electrical issues that I am aware of. Haven't had
this issue before w/ other Jeeps (1998, 1996). tia for any info or ideas.

Paul
