Murphy’s Law… you hop in your prized Chevelle or Malibu on a freezing day, or if you have AC, a super hot day, and fire up your baby. You go to adjust the cabin temperature and……nothing happens. You slap your dash and belt out a few obscenities or something like that. It could be your blower motor, or the wiring, but most likely it’s the blower motor switch. This little electo-mechanical device allows current to flow to the blower motor to warm or cool your interior or defrost your windows. Over time, the contacts wear and switch begins to fail. We are here to help, replacement can be done with a little mechanical know-how, some simple and tools and a few hours. Remember to check your Chevelle or Malibus service shop manual before attempting to replace any electrical device. Ecklers Chevelle & Malibu is here to help when Murphy strikes again.
