93 corvette heater won't blow cold?
I have the electronic climate control. Air will switch to all the diferent modes correctly. Temp goes up and down on control. The display does not flash. I checked for trouble codes according to the manual.Shows on codes.Everything seems to be functioning correctly except air blows out cold. Will not blow warm. Core is not leaking. Does it have a heater control valve that control water flow to the heater core. If so how do you get to it? I can't find a valve in the manual. I'm worried it is the temperature mix door motor. That must be a pain to get to.Need help please.
Thanks

What's your coolant temp? If you're running extremely cool, perhaps your thermostat is stuck in the open position thus not letting the coolant get warm enough to get heat through the heater core.
That very thing happened to me with 2 of my cars.

there was just a posting about this... the heater box can get all clogged with debris... and that sucks...
the other cause can be a bad heater core...
