Hey thats not true.......... I have heat!!!!!!!
I never did replace the incorrect valve i used to replace the broken valve.Hey... I found it thanks to this thread.
Here is how I fixed it for free!
The shaft connects the electric motor gear to the valve gear. Ie motor opens the valve.My '07 is doing the same thing. No heat. If I turn the heat all the way to cold, leave it a second, then turn all the way to hot, it SOMETIMES results in heat.
-What does the shaft connected to the gears do?
-If I remove the shaft, can I still have control of the heat/AC from the cab?
