Hi guys, my Grandma's 2009 Ranger 2.3's heater stopped working a while back. The blower would work but when you would switch it to heat it would do nothing. I told her I would get around to fixing it when shortly afterwards the blower stopped working. I took the blower motor out and jumped it and it worked fine. Then I replaced the resistor and blower motor switch. Each fixed the problem for a couple of days, then back to nothing. Now she tells me it won't pass emissions. The guy told her something about the possibility of some sensor. Does anyone have any ideas?
