A few months ago, my heater fan stopped working properly on my 97 sunfire. Of the 4 possible settings for the fan, the lowest 2 do not work, while the higher 2 work fine, meaning either the fan is on really high, or not at all. Any suggestion of what to look for to fix this before winter comes? Could it be a bad connection, fuse, etc? Any advice would be greatly appreciated!
blower motor resistor died.
and the fix? is this easy to replace?
