is this automatic temperature where you set the temperature? this is behind the dash some you may be able to just feel around to find it to see if a vacuum line is off or motor is working you may have to pull out glove box or a panel under to reach it.

ok if you set the temp it's a whole new ball game. see pic on how to test you may have to pull control panel out if you can't reach wires behind. this is for no air coming out a/c vents which from what I read is your complaint.
