[Vwdiesel] radiator fan

[paul lew]

I'd check to see if the temp is the same across the radiator.
My car had a intermittant fan , bad relay, and finally,
half the radiator was plugged on the thermal switch side, so it always stayed cool enough for the fan not to turn on.

To help me in stop and go traffic jam, I wired a switch to the dash to turn on the relay manually,If you use a VW hazzard swich it almost looks like factory.
The high speed uses the relay, the low speed doesn't it only uses the resistor (mines a 91 jetta diesel)
