I don't have the complete diagram for this HVAC system but this situation sounds like a possible defect in an actuator that opens and closes a blending door under the dash. Some systems are electric actuators, some vacuum. The vacuum ones tend to have these mysterious tendencies, since a small leak can slowly open or close an actuator or the door it controls.

Thanks Mr. Shiftright.
I took the auxiliary water pump off then it worked. Once the car got hot, it started blowing hot air.. You think it might be the auxiliary water pump?

Can you bench test that pump? If it were inoperative, i wonder if it would block all or most coolant flow.

Mr. Shiftright, Thanks for all your help. I check the pump, its in working order.. I went back to Jag this morning, they stated once the heater valve was replaced, the car burns the climate control panel. So I'm looking at $1800+ for repairs.

lol.. I thought the same thing. They stated the climate control module was burnt out due to the replacement of the heater valve. Therefore, while replacing the heater valve it has the tendence of shooting out the climate control module. As per the Assistant Service Manager.

that would depend on whether one pipe is on one side of the valve and the other pipe on the other side. I don't know the system well enough to speculate but of course if you have a hot pipe on intake and one on outflow (from the heater core) then yeah the valve would have to be working and it would seem that the blending doors or actuators are the problem.
