New to the forum. Iam working on a electrical issue.2006 endeavor when you turn on the turn signals they both flash.which to me indicates a short or a ground issue. But people swear its the multifunction switch.how do you test this switch.any other advice to fix this greatly appreciated

 

That is more likely to be the hazard light switch than the turn signal switch

 

ok thanks for the advice i will check out the hazard light switch
