2003 Ford Focus 4 cyl Automatic 65000 miles
My Heather fan only works on speed 4. It will not work on 1, 2 or 3. I need to know how to fix this problem. I have had a suggestion that it may be the regulator and I have a NEW regulator to install, but don't know how to install it. So a solution to this problem is REALLY needed since it's January!
