The engine cooling fan began to run nonstop a few days ago when the dash temp gauge reaches normal. It does not overheat, everything runs fine, no warning lights on the dash, just constant fan. Any ideas.

jps:
Another TBird owner had a fan that ran continuosly and the dealears lots of things I won't bore you with but here's the end result:
"“They originally thought it was the heat sensor... pulled the manifold out replaced it and it was still not working, they removed the radiator and flushed and clean it... still no luck, ran it with and without the thermostat and still the fan was getting false reads when monitored with a laptop. The fan was running at full power without shutting off. The field service engineer came back out and took a look and said that the heat sensor is very sensitive and malfunctions if it is touching metal. So they removed the manifold again and trimmed the ends of the sensor so it would not hit the board. They say it is now running up to 204 without the fan kicking on light fan on at 215 which goes down to 199 when the air conditioner is on. After 3 weeks in the shop I picked it up yesterday and so far it's quiet. I smell a little hot plastic off the engine but have driven it about 30 miles so far without issue. Hopefully this is it.”
And he's still happy after 2 years.
