Anyone else have this problem? How did you fix it?

Replace the TCCM.
Check out
www.Car-Part.com for used ones. That's what I ended up doing.
Also, your replacement switch very well could be BAD as well. The dash switches are incredibly flimsy and break EASILY. They are cheap enough to buy new and replace.
Check out
www.RockAuto.com for New switches at cheap prices.
Let us know how it works out.
