rsorg Posted July 6, 2015 Share Posted July 6, 2015 Not sure why but my under hood light , and interior lights flicker when my car is idleing, not to the point that it is annoying , but should I be concerned, thanks Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted July 6, 2015 Share Posted July 6, 2015 well the under hood light has a mercury switch that could be vibrating while running as for the interior lights, the dome lights or dash lights? the dome/under dash lights are ground controled, it could be a loose connection to the orange power wire or poor grounds in the door switches Quote Link to comment Share on other sites More sharing options...
cbolt Posted July 6, 2015 Share Posted July 6, 2015 Does the vehicle also vibrate at idle? Quote Link to comment Share on other sites More sharing options...

Rob Peters Posted July 7, 2015 Share Posted July 7, 2015 Your negative battery cable should have a short wire coming off of it at the battery terminal clamp. That wire should attach to the passenger fender with a screw or bolt. If it is missing it wi.. cause the symptoms you describe. rob Quote Link to comment Share on other sites More sharing options...
