I have a 2006 jeep Grand Cherokee ac blower worked fine stopped at home got back in the car
after a few minutes and now it want blow
could be fuse or blower resistor.. try on other settings if it will blow on high probably resistor has went out.. If it will not blow at all check fuse and or the wire going into the blower motor.. I have a 99 and it would stop and it was a loose connection at the blower motor and or the motor going out I could move the wire and it would work for a while and then do it again.
