I have a problem with a Xantia HDI 110 - the Radiator fans are both on
continously. The coolant level is unchanged and the temperature guage
reads as normal. The fans run from switch-onn, even when the engine is
cold. I assume that there must be a temperature switch or similar, which
is separate from the temperature sender used by the guage, which must be
broken. Is this right? If so, whereabouts might I find it?
I had a quick look round the engine, but am little wiser.
Thanks for any help,
I had the same on my Xantia, this is what I found : The fan motor is under
the passenger side glove box, & is accessed by removing the furry backed
trim. The fan unit is held in place by 3 screws, & it contains 1 or 2 large
transistors. (2 if you have air con, 1 if you dont). These have a habit of
failing, & causing the fan to be permanently on. Your local scrap merchant
should have one, for about £40, but you may have to take it off yourself. On
the other hand, it may be the temerature control unit that has failed. This
is, I am led to believe, somewhere under the front scuttle, & I have no
experience of this. Hope this helps. Ray
If these transistors are the problem, than just replace them.
Any shop selling electronic parts should have these transistors.
Perhaps you have to solder a little bit, but that is always
cheaper than £40. The transistors self, aren't expensive,
I think somthing about 20 tot 30 eurocent each.
(sorry don't know how much pennies that is, I am from the Netherlands)
btw: I am not (originally) Dutch, but I come from a country that was
a colony of England. And there all the cars are modified to keep the
fans always running, after starting the car :-))
(This because of the heat in the summer)
Good luck fixing your car.
