Hello All,

My fan doesn't go on at the lower speed/radiator temp. It will, however,
go on very loudly if it gets to the hotter temp.

My thinking, just from looking at the electrical diagram, is that the
thermoswitch is out. Either that or a relay, but I think the relay is for
stage 2, the higher setting.

Since the thermoswitch is $29 from VW (plus the O ring), not very
expensive, It can't hurt to try.

But does my thinking sound OK?

I drive at highway speeds most of the time, so the engine hasn't gotten
warm--but I don't consider driving without the fan real secure. Y'know,
what if I get caught in a traffic jam?
(Well, I guess I'd turn the engine off. But still)
