The other day I installed a new cd player and after testing the radio it worked and I thought I had done a good job. This morning when I turned on the head lights all sorts of things happened; My tach goes to the off position, my instrument cluster lights go off and both turning indicator arrows turn on with no blinking (although the lights outside the car work properly). Just wanted to get some advice before I go and screw it up some more. Thanks for any help!
