Ok
One more thing. I am thinking of blowing off this core problem for now. I am going to seal it off and use a space heater instead. I have seen a lot of 12 volt heater blowers on the net. They use 12 volt of course and some use 20-25 amps. Is this a problem in these vehicles? I live in the south near the coast so it doesn't get too cold.
Thanks cashmony
