Took my VTS 2001 into citroen the other day to get them to run a diagnosics check on my abs sensor.
In an unrleated matter the mechanic pointed out that one of the relay covers (purple) was missing and the relay that is linked to the cooling fan was knackered. They gave me a replacement relay which I said I would fit myself.
When I fit the relay the cooling fan comes on continously and does so even when the car is cold. I rang citroen and they said it might be the green relay that was also knackered so I replaced it with another but still the same problem. The only way to switch the fan off is to disconnect the purple relay.
I've tried scrapping the contacts in case it was a poor connection but didn't help.
The temperature gauges inside the car for the coolant and oil temperatures seem to be operating ok.
I also noticed that there is a weird looking device (silver cylinder) just above the fan, in front of the radiator, which appears to be connected to the relays which I suspect is a thermostatic switch. This device is tricky to see due to the fan housing. Can anyone confirm what this device is, and if it was broken would it keep the fan on?
I'm going to ask citroen tomorrow but thought I'd ask here first.
I've tried looking at the haynes wiring diagram which I think it describes this device as an engine cooling fan resistor. Sure'll if it was broken the fan wouldn't come on but at the moment it is! Can't get my head round it!
Any help would be great.
