Greetings all,

The Background:
The cabin temperature sensor on my '97 S500 is squealing like a banshee so I ordered a new one (140 830 0472). This is a small sensor and a fan to draw air over it. The bearing on the fan must have gone bad. Oil turned a loud squeal into a soft buzz still much to annoying to live with. Besides the part is only $19.50.

The Question:
After I replace it will there be any calibration required? My only other experience with climate control is on a Chrysler and whenever there was a large change in season (Fall and Spring) I had to calibrate the system. Is there any similar process in a MB?

Thanks.
