my heater motor only blows out my window defroster, WTF?
I turned on my heat yesterday and it only blows out the window defroster. It does this with the AC also. What's wrong?

The window defroster is the 'default', when the controls aren't working. Pull the control unit out, check the connections, check for vacuum from the engine compartment. If it's connected good and has vacuum from the engine compartment(the engine needs to be running), then the control is probably bad. If you don't have vacuum at the control, check under the hood for a broken or unconnected vacuum line.
