NISSAN SENTRA KNOB PROBLEM

2005 Nissan Sentra • 160,000 miles

I have a Nissan Sentra 2005 and the control knob for the ac/heat is stuck blowing air out the front. I cannot switch it to defrost the windshield.

Knob is stuck or it can move but the air flow is stuck on one position?

It's blowing air out the front and I can turn the knob but it won't change which way the air is blowing. This is only really a problem when trying to defrost my windshield when it's cold outside as I've been having to drive with the windows down.

Check the intake door motor and linkage adjustment.
