I know very little about cars, but my father has a 97 Taurus whose battery
keeps dying because the interior dome light stays on all the time. The
dashboard switch (instrument panel dimmer/dome light on/off) does not shut
the dome light off. I looked under the hood for the fuse that might cut the
power to it, but could not find one.
Also, the DRL were doing the same thing -- not going off when the ignition
was shut off; my elderly dad took the car to his neighborhood mechanic who
disconnected them, which solved the problem for a while. But now we have
this dome light problem. Any suggestions?
