Just replaced the water pump on my 2008 which was a a ridiculous idea by ford to begin with. I dropped the engine cradle with suspension and everything still in tact. After the water pump swap I installed everything back into the car and the engine runs like a top. Now the transmission makes a whining sound kinda of like a power steering whine. It only whines after it shifts into 4th and od. I never did anything to the trans during the water pump job so I have no idea where it comes from. Any ideas?

All the blend doors seem to be operating fine.

Bought a new heater core and was in the middle of tearing the whole car down to get it off. I pulled the hoses off the heater core and put a new piece of hose on one side and blew through it and felt like there were no restrictions. Put the water hose to it and it ran out as fast as I put it in. Changed thermostat and started the car and felt under the dash on the inlet/outlet of the heater core and both were ice cold. Eventually it he thermostat opened and just the bottom tube got hot. No heat coming out of any of the vents. Any ideas before it ends up at the scrap yard?

I don't see it being blocked ducts because the air blows the same volume from both sides, just not hot on drivers side. I manually operated the blend door and the temp never changed on the drivers side.

I searched and read all the posts about heating troubles with the edge. I have an 08 sel without dual climate. The heat is very hot on the passenger side but cold on the driver side. I pulled the panel off under the column and watched the blend door as I turned the temp from cold to hot and back and the blend door actuator is moving the full range of motion. I pulled the actuator off and moved the blend door by hand and nothing changed on the drivers side. I don't mind changing the blend door on either side just would like to hear any ideas of what it might be.
