Re: [DML] ATTN: Michael #2944 (Cooling Fans Won't Turn Off)

[Martin Gutkowski <webmaster@xxxxxxxxxxxxxx>]

John, the original problem stated that the fans come on when it gets hot 
enough but the guage shows that the engine never cools down enough for 
them to turn off. This does not sound like the otterstat to me as the 
guage would suggest it's doing it's job. Plus if the otterstat had gone 
wrong such that it is always closed, the fans will run continuously with 
ignition. You would never be able to see the fans cycling on and off 
with AC, as described.

It's perfectly conceivable that there could be a wiring fault between 
the fan fail socket and one of the fans - the connectors to the fans are 
open to the road for example. If one fan has failed, the car will 
struggle to bring its temperature down, hence my question whether it 
comes down whilst driving along.
