2010 sebring a/c fan speed
 

What up guys, new to the forum.. any help would be great. I got a 2010 sebring, when I turn the a/c-heater fan on to high the fan motor turns off. I've replaced the resistor by the fan motor and still does the same thing. I put a test light on the fan motor with the fan on and the light was bright switched to low the test light dimmed, medium the light dimmed more and when I put it on high the light just turned off.... do you think it could be the fan or the speed control????
