I looked for one of those small push on retainer/clip things to hold the metal arm from the blend door to the grey arm on the lower end near the glove box, to no avail. The metal arm is back on the grey arm and now, when I reach up and move it by hand, I have full heat. When adjusting the temp from full hot to about 70, it'll move by itself, but wont move it back to hot by itself. Oh well, it'll be good enough for this winter.
