I have an 85 blazer with the air conditioning heating system. It is all messed up and don't really want it anyway. I have a 82 non ac donor pickup. I would like to switch it all over. Has anybody gotten this deep into the heating/cooling system? What problems might I encounter? /forums/images/graemlins/confused.gif Considering cutting out the dash steel to simplify and weld back in later. Does that sound crazy?
