Can you elaborate on what the mechanic told you about it being behind the dash? There is absolutely nothing online that shows where this resistor is. I have a 2016. I also dont follow where Mikeyk’s picture is. I have looked all over and I don’t think that’s the same as my 2016. I replaced my blower motor and I still have the same issue, after 10 min or so the fan slows down then stops blowing much at all.
