#1 of 26 floor heating problem by vic2010

When the climate control is in the “Floor” position, air does come out from the floor vents. However, as a move the temperature lever from cold to hot the air no longer comes out through the floor vents but instead comes out hot from the upper air conditioner vents. Any ideas are appreciated.
Thank you

may be a vacuum leak. Vacuum controls vacuum motors that open & close diverter doors. 3 valves, one for inside/outside air (paasneger side floor area), one for floor defrost (Double action motor), and one for panel.

Hello My Friends,
 
I am about to buy a Ford Mercury Grand Marquis.
I already know one to buy, but theres a problem with the fuel pump. Of course i could buy a new one, in case. But i think its possible that the emergency shutdown was activated for some reason.
 
Does anybody know how to reactivate the fuel pump in this case?

I changed the blown gaskets.It still leaked water into the oil. I took the heads off again, and had them resurfaced. I physicaly checked the cylinders when I had the heads off. They seemed fine with no cracks or scratches I put them back on wtih new gaskets. It still leaks water into the oil. I have heard that the intake manifold may need to be resurefaced also?

Car sat for several months. Worked just fine. Now, no start. Engine cranks but no fire. I suspect it's not getting fuel. Fuel shutoff is NOT tripped. Fuel pump fuse is NOT blown. There is NO spark but I suspect that's because there's no fuel pressure.
  
Another weird thing is the ODB2 code reader produces "Error" after trying to read any codes.
  
Any Ideas out there as to where to look?

How charged up is this battery, or are you just jump starting it after a long sleep?
 
If you haven't done so, charge up this battery fully on a charger before you start diagnostics.
 
Here's a good TUTORIAL on no-starts to give you some ideas:

Does your Grand Marquis have an oil cooler in the lower radiator hose? It is a metal tube in the lower hose that runs parallel to the radiator and is connected to the oil filter base by two rubber hoses. If it does you should check or replace it. We had quite a few Police cars with oil in the water and vice versa in the mid to late '90's due to leaks in the cooler.
