The tail lights remain on after light switch and ignition
are turned off. Any suggestions how I can address
the problem, or should I take the vehicle to a repair shop.
Replace the defective light switch. You can do it yourself.
However, if it is the brake lights instead of the tail lights, it
is a different problem. Two common causes:
1.) Brake light switch near brake pedal is mis-positioned
or stuck in the ON position. Readjust it or replace it.
2.) Brake light distribution section of turn signal switch in
steering column is stuck in the ON position. This is
a more difficult thing to get at, requiring removal of
the steering wheel. Decide for yourself whether you
want to tackle this job.
