Can anyone tell me why my fan will not turn on when my 2001 DS650 runs hot?

Your temp switch is probably bad. This is a common problem on the DS. It often goes bad when it gets water in it. You can use a voltmeter to test if juice is getting to the switch and wether it turns on when the motor comes up to temp. Hope this helps.[img]i/expressions/face-icon-small-smile.gif[/img]

Hotwire the fan as well to verify that it still works. The brushes and wires vibrate apart over time and you end up with a dead fan- they are really tough to repair - new fan time!
