Thermo Fan for Mercedes 270 CDI faulty where can I obtain a good second hand replacement in Melbourne, Victoria

It appears there is sufficient water in radiator, have had fault diagnostics done by a Mercedes dealer who have indicated it may be the control unit on the Thermo fan which only comes as one complete unit. The control unit is probably faulty and not sending correct signal and appears thermo fan is not kicking in to keep temperature down. On gauge it indicates that temperature is running hot to just under 100 degrees, is obviously worse the higher the air temperature on a hot day?

SOURCE: Radiator fan in my 2003 crown victoria runs continuosly

No, the fan is supposed to come on only at certain temperatures.

Trace the wiring from the fan back, there should be a temp switch/relay in line. If there isn't,then someone has bypassed it and wired the fan to run when the car is running.

SOURCE: Intermitant temperature

Check to make sure your thermostat works right by monitoring the warming up of your engine. With a completely cold engine, start and run the engine for a few minutes, then put your hand on the top radiator hose to monitor if and when it gets warm as the thermostat opens more and more and note the gauge reading( if it works) the top radiator hose should be unbearably hot within 5-8 minutes. If the therm. opens right it should close right aswell, staying open a little while eventhough the radiator may have cooled may be what you are experiencing causing the rapid cooling and is nothing to worry about. The Hose should not get warm very soon after starting the engine. Regarding you gauge, lets take one step at a time, verify proper op. or the therm.

SOURCE: want to replace the air conditioning heater control unit (Scenic)

this has to be a faulty switch or varable speed resistor.
youre saying you have no control over fan. i see this when people bypass it as speed resistor is expensive so they wire it direct.

this is either a sticking fan relay or the sensor is in the thermostat housing, try the relay 1st.
