Alaskan_Legacy Posted July 6, 2009 Share Posted July 6, 2009 The end of last winter I noticed that after driving for a while, my heat would start getting cooler. It seemed like it would be hot for a bit then cool off. Well now my AC won't work, plenty of airflow but definitely not cold. Now I try the heat again, and same deal, lots of luke warm air. What could affect both of them considering the blower is working? Link to comment Share on other sites More sharing options...
ehsnils Posted July 6, 2009 Share Posted July 6, 2009 Try to reset it by disconnecting the battery for a few hours. It may help. If not it may be a sensor that's bad. Other items are the thermostat that isn't working correctly or that you have a low coolant level. Link to comment Share on other sites More sharing options...

HarryN Posted July 6, 2009 Share Posted July 6, 2009 Might be the heater core and cooling system leak, or even holes in your HVAC hoses. Link to comment Share on other sites More sharing options...
snow05gtRI Posted July 7, 2009 Share Posted July 7, 2009 the heater issue of it not working could be linked to the thermostat. it gets stuck open so it can never close enough to heat up the coolant and supply you with warmer air. dunno why this would make the AC not work, though.
