I need some help. I have a 2004 Trac 4x4 that isn't producing heat as warm as it normally has in the past. The engine temp gauge reads normal. When I turn the temperature knob to cold, it blows cold air and when I turn it to hot, it blows barely warm air. I replaced the thermostat last night just to make sure that wasn't it. It didn't help at all. I can see that the vacuum controlled heater control valve on the heater hose moves when I turn the heat off and back on so I assume it's working right. Any ideas on what to check next? Could the blend door be working partially? I need good heat...please help.
