The blower fan inside the truck blows just fine when you first start the truck but will cut off and not blow at all after a few minutes. Then it will cut back on after a minute or so. It does this off and on all the time. It seems if it were a fuse it would just cut off and not come back on. Any idea what it might be? Thanks for all help! This is a Dodge Ram 1500 Sport Edition. ---

The next time the blower stops working, pull over and reach under the passenger side of the dash and tap on the blower motor with the handle of a screwdriver. If the blower starts working replace the blower motor. Tester ---
