I have searched and searched but cannot find anything that sounds similar. I have a 1986 300 SDL and recently my interior lights and seat belt lights won't go off. The interior light stays on unless I switch the position to the off position only, but then the seat belt light blinks until I turn the key off then on again, I have had to get a jump start 2 times this week alone. Please help if any is possible

Thank you
