Total newbee needs advice
i have no idea were to start looking ,iv just recently obtained a xantia TDSX estate 1.9 1996 P reg desol .and have found that the internal fan is faulty ie it is permantly blowing and can not change its speed or turn of via slider,i can alter the temp ie hot cold ,it also has air con that fails to activate ,i spoke to the ex owner who was aware of the fault and asures me he had changed the fan but this failed to rectify the problem,any ideas?
In the absence of any other replies I can only offer the info that my Xsara had a problem with its fan whereby it would only work on speed 4, ie. high speed. I found out it was a problem with the speed controller ...it works like a volume control and basically (so I understand) the 4th or high speed is the natural speed of the fan and anything below that is the result of the 'volume control' (if that makes sense) being turned down. Could be that yours has been bypassed so that it runs no matter what the speed control is set at. It might be something to do with the air con though and I'm afraid I don't know anything about that. Hope somebody comes on and helps you.....I get a lot of help from my local main dealer who is quite happy to 'have a look' gratis....might be worth popping into yours and see how the land lies.

Fans are my patch, but I’ve become very lazy of recently.micitroen wrote:In the absence of any other replies … Hope somebody comes on and helps you.....
Is the previous owner certain that he replaced it with a known good one ?
If the fan is spinning flat-out all the time, it may be the output transistors that are shorted.
The replacements are MJ11015.
There are quite a few threads on the topic here, and I’ll edit them in if and when found.

If you put ‘blower’ in the search, it turns up 147 topics.
