Heater problem
2003 Mercury Sable 6 cyl Front Wheel Drive Automatic 80000 miles

The heater blower only worked on high speed. I replaced the heater motor switch resistor, this corrected the problem for about a week. Now the heater blower only works on speed. What could be the problem.

Do you
have the same problem?
