This started after bad turn signal replacement with steering column smoking and light switch on fire. Replaced light switch, steering smoked few more times (less smoke each time) then cruise control become intermittent till stopped working completely. Wipers were next now radio degrading faster as neither wipers or radio hardly come on or stay on long anymore. Mechanics never have issue (bother to look)when had truck in the shop. Aside from fuses under panel what are some other likely spots.
