    My grandfather has a 92 Seville with the same exact symptoms (all of them), it would work correctly some days and some days it wouldn't, now it is stuck on defrost/floor. http://www.cadillacforums.com/forums/cadillac-seville-cadillac-eldorado-forum/205943-gremlins-c.html

    Have you found a solution? I'm disappointed a new programmer didn't work for you, I actually considered buying one a year ago if I was able to actually find the right part. I have the service manual and spent some time today searching for leaks under the dash with a vacuum pump, didn't find any. My current best guess is the air mix valve or some mechanical linkage issue, I'll update your thread soon with anything I find, and keep me posted as well.
