Re: heating problem
With the temperature slide moved off the cold side there should be no vacuum at the water control valve. This is the valve under the hood that you replaced. Check that first.
The temperature slide is on the control head on the dash. In the full off position (all the way to the left) vacuum is applied to the under hood control valve to bypass the heater core.
