[s-cars] Electric Fan not working

[Tom Green]

For your concern about coolant temps, you can check the climate  
control reading to verify that the dash gauge is correct.  The climate  
control section of the quattroworld UrS forum FAQ has details.  That  
should give you confidence that driving the vehicle is ok.

I suspect the coolant warning light is a coolant quantity alert rather  
than a temperature alert.  If you disconnect the float level sensor  
wires from the bottom of the coolant tank, that might confirm that  
there is a malfunction in that sensor.  I doubt you would have a  
temperature alert in the autocheck when the temp guage and sensors  
report normal temps.

You already received several responses for checking the fan.  Follow  
that advice from Ed and check the fan relay in the plenum area relay  
box just in front of the drivers side windscreen.
You should check if the electric fan turns freely by hand.  When I  
first got my avant and checked out a noisy fan, the blade almost fell  
off in my hand.  If there is no power to the fan, I would
check the large (60amp) fuse in the drivers kick panel.  It takes a  
few minutes work to remove the panel, but you need to know if you have  
no power to the fan.

If your test of the relay by shunting the connections with a wire show  
power to the fan but it doesn't turn, you might help it start by hand- 
carefully, since it is very strong-remember the 60 amp fuse?
