i just wanted to let everyone know that my a/c works again, at least for now. heres a run down of what i did:
1) disassemble dash controls
-unclip the temperature and fan location wires
-pull off surround
-disconnect the two wire harnesses
-remove 4 screws holding controls to surround
2) remove the front of the control unit, you will have to pop off the knobs, i used a plastic knife
3) remove orange plastic cover thingy.
4) now this is where my experience may differ from yours, there was a white plastic nut boucing around inside the unit when i took it apart, after examining the system i determined that it was supposed to be holding the fan speed switch in place, and was not. because of this, i am pretty sure i was getting a bad ground in the connection. i came to this conclusion because when i held the fan speed switch in my hand it worked perfectly.
4) so i re-installed the nut, put everything back together, and it works. every once in a while when i switch speeds, the light flicks for the 1/4 second during the speed change, but it works on all 4 speeds for now.
