Customer Question

Where might I look for intermittent slowing of high speed on the AC blower in my 2005 Montana SV6? (116k miles)

Hi there.

More than likely, you're looking at a bad blower resistor or connection to it. Does your Montana have the manual or automatic temperature control option? Front or dual front and rear A/C?

Customer: replied 1 year ago.
It has the red-blue dial control for temperature and a front A/C. The blower speed slowdown is slight but really important when a person is "maxing out" the unit for comfort on a hot day.
