Location of blower motor resistor

Hello, if heat is barely coming out of the vents, how can you be sure the blower isn't working? The resistor typically prevents use of all fan speeds except for "high". If your fan is blowing on high, but not other speeds -- well, that's a different problem than you have described. I'd strongly recommend checking for debris blocking the fan, a concern with the mode door function, a possible fan motor issue, switch issue, wiring issue, relay issue. Too hard to know what is going on without actually experiencing the problem you are having, and then also being able to approach that problem relevant to the concern. www.repairpal.com/repair-shops
