I asked in another forum & was told it could be the combo turn signal/dash & tail lite switch. Well it wasn't the turn signal switch BUT by checking that I found that a fuse that looked good was bad. I figured out which wire should go to the dash/tail lites on the combo turn signal/lite switch & when I jumped it the lites came on & the door bell dinger started to work again. I replaced the fuse & everything worked......joe
