BLOWER MOTOR

2000 Mercury Marquis

Heater problem
2000 Mercury Marquis V8 Two Wheel Drive Automatic 121000 miles

My 2000 mercury grand marquis has started having blower motor issues. When it is turned on, the blower runs high then low then high, it acts like there is a loose wire or something. When it is blowing, it tends to only blow high but it goes on and off constantly. This is a new issue, I have had the car for about a year and it has run great until just recently. It really acts like a loose connection or wire, but I have no idea where to start looking. Help!

If it works on high only, chances are the blower motor resister is bad. Check that and let me know what you find.
