My blower only works on HIGH
I have a 2010 Ford F150, Over the past year, the A/C heater blower has
gone from working on all levels, 1 thru 4 to just working on HIGH. I have
replaced my resistor and that did not correct the problem. At the time, I
thought the problem must be something else then since it still worked the
same as with the old resistor. But I have since learned that the resistor is
bypassed on the HIGH setting. So now I'm wondering if the new Resistor is
DOA. Is there any way to check if it's a dud or not? Any other suggestions
on what this could be and how to trouble shoot? BTW, I am not
mechanically inclined. Just like to learn new things and enjoy a good
challenge
