Little history:
2001 s40 Turbo
Occasonally the fan would go to full speed then back down to what I had it set too. This happens maybe a couple times a month other wise the system worked fine.
Today:
Temp set to 74, fan at setting 2, no AC, just heat.
All of a sudden the fan came on full speed and the air from the vents got cooler. The fan control does not work, but I can shut the fan off. If I turn the heat up higher I do get heat, but setting 74 is cool now.
Anyone see this before? How about ideas and component locations?
Thanks, Ed
