Does anybody know what part controls the fan speed and where it would be located on my ride....
Suggestions of whether this would be a good DIY project?
If it is only the Fan speed that is acting up chances are that your FSU is on its way out... for sure this is a DIY use these instructions:
PS. Do it before it drains your battery and leave you stranded some where.
