Hey guys , wondering if this is the signs of my heater motor goin, makin weird nosies, yet its always done that in the time ive owned my truck and i have a couple other buddys with 96 to 99 fullsizes, that make noise too.. but in the last month or so, it cuts right out, give it a lil tap or hit a bump and it will turn right back on, ive checked the wires, all seems good also seems like the speeds arnt as fast as what it use to be... Just wanna get this figured out here quick , as the snow is startin to fly here tonight, d**n winter...

go ahead and replace the blower motor before you are out in the snow and you cant see
