My axillary fan doesn't seem to be kicking in. While idling around town today I noticed the temp creeping almost up to 100. I checked the service records and the axillary fan belt was replaced last year, so I'm guessing it was checked at that point. I checked the fuse and it said that it could be fuse# 20 or 41. I found 20 and it was fine. I can't for the life of me find #41. Checked all 3 fuse boxes I know of but don't see it. Any ideas??
