Hi, I have a 1998 Ford Taurus (114,000 mi).it is winter and the problem is that when the car is moving or accelerating the A/C blows warm air ( as it is supposed to) but when the car is idle (e.g. stopped for a red light) the A/C blows cool air, I changed the thermostat, which was totally worn off, but still the same situation. I don't know what to do?
Taurus 98 A/C Problem

In what position is the A/C control?
I think the problem is that either the compressor is on, if the control is in defog or defog/floor, so that dry air will go against the windshield or the air is just too cold. Eitherway, when the engine is turning faster, like when you are moving, the water pump is turning faster and, that is making more hot water come up into the heater.
I suspect there is also a partial blockage in the hoses or more likely the heater core.

It's probably because your water pump looks like this:

when it should look like this:

This was a TSB issue w/ 96-97 Taurus & Sable, it likely may have affected the 1998 too.

Quite likely they didn't catch it right away, as it would take a while to deteriorate - who is the bright engineer that decided to use a stamped sheetmetal impeller? *I* even know better than that...
