2003 c240 50k miles. The A/C fan came on when I started the car and began blowing strong and then a minute later stopped. I shut off the car and waited a few minutes to restart it. when I restarted it the fan came on again for a few minutes and quit again. I still get cold air from the vents and the a/c is not turned off but no fan, even if I turn off auto and use the fan knob. Could this be the blower motor regulator? Any info is welcome, car is out of warranty so I dont need a big service bill. thanks
