84 Aspy has bad cooling fan switch?

Noticed bike was running a bit hot late last season in town traffic. After just getting it serviced and back on the road again I began to think on this running hot issue. Then it dawned on me that maybe my fan was not coming on. I knew it used to come on when sitting at idle for long periods b4 when I 1st purchased the bike and was going through my carb problems :lash:. Sure enough after letting the bike idle long enough to get hot, no fan. I did some digging on the web and found some info on where the fuse was for the fan switch. Took the seat off, found it and it looked fine but I switched the 10 amp fuse for the spare inside the fuse holder anyway but no joy.

I suppose my switch is at fault. Are there any old topics on this job on the site? Thanks!
