Thanks to this thread and a few others:

I was able to fix my "AC leak in the evaporator" that was going to cost me at least $2,800. Thank you all very much, I had gone 4 long years in the VA summers sweating that out having no idea that in 5 short minutes it could be remedied.

Now my center vents don't work at all and I can't switch the flow from the dash to the floor to the windsheild defrost. It only blows through the side vents. In the process of correcting my problem by fixing the EC button I'm afraid I may have reset something completely.

Any thoughts?

Thanks in advance!
