I tried the test you suggested and you are correct, it does not go into low speed with the air on nor did it go to low speed whith the temp around R. Now my AC hasen't worked in over a year ( I assumed it needed charging and didn't bother having it done) so I don't know if that would have an efffect on the test or not? Even assuming that the low speed portion of the fan is not working, the high speed obviously is, it should still not rise above the high speed temp while driving or am I missing something here? Also the issue of reseating the temp sensor seems to clear up the high temp? I wish I new more about these things.
Thanks for all your help.
