Will not blow air out of defrost. Air is coming out of dash vents but when I hit the defrost button (windshield) nothing happens.

You should be able to access the actuator from under the dash on the driver's side. Watch it while you operate it and see if anything is responding or getting stuck or broken. There's a lot of mechanism for it to operate.

try pulling fuse for heater inside car for 60 seconds then reinstall it may reset it if not then press off auto and recirc at same time for codes then get back to us. Of course this is for auto temp control only which I think is in this car
