my wife's 07 MC (74000mile) had any single problem until last week.
Yellow Engine check light came on.
replaced thermostat housing and reset the engine check light so light is off now. Also cleared bubbles out from new coolant and it looks everything fine but something wrong with Fan.
Fan kicked in when the engine is getting hot about (102c-105c) so Fan is working correctly but when fan cooled down the engine to slightly below (80c/176F), the fan does not stop until the engine is off. as soon as fan start to run, the fan just keep running until turn off the engine.

Isn't the fan should be stopped if the engine is cool down?
I am wondering what is the problem with the fan???
can it be problem with ECU? or others???
