I have a 2004 mercury grand marquis with 91,000 miles (4.6). I have no heat, and this is a problem because its winter! I recently changed the thermostat, but even when I have the climate control on the highest setting (90 degrees) and the fan on high, its still blowing cold air.
The engine runs at normal temperature, does not overheat at all.
Tested the EATC system, as described below and the only code that showed up was 025.
Can anyone tell me where in the dash I can find the air blend door actuator?
have the same problem?
