The blower was only running on highest speed when that gave out (in a snowstorm at -25C)...fortunately by cracking the sunroof I was able to pull enough heat off the engine to keep the windshield clear at highway speed. I am quite sure it is the blower and not the switch but could be wrong. Has anyone had this happen. How difficult is it to replace? Does anyone know of a post describing the fix? I had heard that a Caprice blower will fit fine and I can buy new at the local auto parts. Thanks Greg
