Coolant level is fine.

Closed heater valve? How would I get it back open? Is this a missed connection due to motor work? Is this a climate control problem and possible replacement needed? Perhaps a lubrication issue? Wierd that it happened after the motor work. I am confused.

Do you have do any removal of the A/C system to get to the heads. Why would the heater valve all of a sudden be closed?
