Daylight Running Lights staying on.

Just started a new problem (as if I needed more with the 94 Buick MAF sensor).

After driving the lights will sometimes stay on, and stay on for a long time. The switch doesn't have to be turned to turn the lights on their automatic, and fooling with the switch does nothing.

I can even sometimes take the negative battery cable off, and put it on in 5 minutes and the lights come back on. Had to leave it off all night, in order to get the lights to stay off, without discharging the battery to nothing.

Sometimes the inside lights stay on as well, but not verified. (I wasn't there). There is no switch/scroll wheel on this car, to change the duration of the lights staying on/coming on at night, like my Mercury Sable.
