97 f150..base 2 dr.4.2 automatic...Ok...air blows cold then sounds as if door in dash closes or moves then blows hot. Turn it off wait a few seconds and air blows cold. For no apparent reason it changes. Seems to do this often in stop and go traffic. Worse time of course. Thanks for comments.

You haven't lived until you pull the HVAC case and replace a blend door the right way
Pretty big job
Steering column out, dash on the seat for starters
That blend door job should take about 9 hours to do it right
