[s-cars] Electric Fan not working....

[Jim Fleischer]

Okay guys,

I've done a bunch of research on the archives and on Quattroworld and am still kinda confused as to where to start on this......

To recap......coming home last night my Coolant light started flshing......topped off reservoir with coolant and monitored temps on the way home, and kept the heat on just in case.  Light continued to flash, checked 25A blade fuse left side of dash (it's fine) and tried to get fan to work by putting A/C on (A/C has worked fine in the past.)  Fan does not come on at all.  Drove 15 miles on country road home, oil and coolant temps at or below normal on way home.

Question I have is.....will any of the coolant sensors malfunctioning keep the fan from coming on with the A/C on, or should I only be looking at fuses/relays/fan itself?  Without a bin full of relays, etc, how does one test a relay?  I've heard of a "big ass fuse" by passenger kick panel, not sure which one this is.  Also there was a post regarding a blue spade connector behind the drivers headlight.....any help?  Also, any tips on getting 12v of power directly to the fan to test it?  I'm not great with electrical and don't want to short something out.....

Thanks all......seems like after around 100K miles of relatively trouble free driving, I'm encountering a bunch of age/miles related BS!

Best regards,
