dome light problem solved....dome lights worked sometimes....found that the contact point from the u shaped clip that holds the bulb to the metal strip has been loose and not making continues contact. I removed the unit and used needle nose pliers to squeeze the contact clip to tighten the contact point. be sure to tighten the circular ends so they contact the metal strip. replaced one switch as is seemed to be bad. part # 924-798 Oreilly auto parts $19.99 2 switches. lights have worked ever since so I feel I have the problem solved. Good luck .
