Im new here and I hope someone can help me out.I recently purchased a 1994 Sierra sle.The heater adjustment does not seem to be working.I push the button to go to full cold,the little marker goes to full cold but the heat still stays full hot.The blower only works on medium fan,I assume thats just the blower reistor.I really need to get the heat to go to cold,summers comeing and I dont think I will be needing the heater!lol
