So when i turn the auto temp control on, it works fine at 60...blows some ice cold air at me, but then i went to turn it up to get some warmer air, and usually that happens at about 69-70, but i pushed the temp all the way up to 86....still getting ICE cold air blowing at me at FULL FORCE...as if i never moved it from 60. At about 87 it gets a little warmer but to get hot air coming back through i have to set it to 90...any ideas what could be causing this error?

heater core or your climate panel is busted and not sending the signal

 

but its summer, why would you need to heater ?

 

morning drive to work

 

Usually that is a bad sign. But it sounds like ur car is not overheating so it nutting too serious. My friend drove around in the dead of winter without a radiator. At the time it was his crappy car and he couldn't afford to put a new one in. It was so cold the engine didn't overheat for the couple of days it was like that. But he didn't have heat at all. I would guess on his car it takes heat from somewhere along the lines of the coolant.
