Heater - CITROEN XM Internet Reference

The Electrics, Dashboard and Heater

15 Heater (4)

I also discovered a problem yesterday while cleaning the car:
When I removed the rubber floor mat on the driver's side I discovered that the carpet was absolutely
soaking wet! I checked around the door, but couldn't see any signs indicating that the seal is defective.
The passenger side was dry.
Are there any likely places water could seep through? Pedal assembly? Steering coloumn? ???

Look at in air condition drainage if you car equipped

It could be the wind screen. Check under the dashboard if you can trace any water or rust.
Wet floor - heater matrix
There is an inherent problem with the failure of the heater matrix on XM's. You may be fortunate that it
is only the O-ring seals that are leaking, or it may be the matrix that has died. The easy way to find out
is to look at your water level in the tank. If the level has dropped, then it will probably be the heater. If the
water level has not dropped, then look elsewhere.
Several of us have changed the matrix. So if you do have to changae it, it is possible to do so without
removing the complete dash ( as citroen will tell you).
Good luck.

If this is the case (on a LHD car) the water would be
at the passengers footwell.

It seems that you have got the patented Citroen time delayed swimming pool effect, guarranteed on any
XMs with a heater matrix (ie. all of them). I'm told that a failed heater matrix happens to all XMs in time
- so mine is still to come :(
======
Described as a 'common problem' or 'design fault' by most Citroen specialists, the heater matrix will at
some stage in an XMs life be responsible for turning the front footwells into paddling pools - paddling
pools with antifreeze. Getting heat from the engine into the interior of the car is the sole purpose of the
Heater Matrix and it is situated inside the center console (behind the radio). Ironically, it tends to break
in the summer when you aren't using it. Perhaps it thinks your feet
around in water Removing and replaceing the matrix is a tricky job because it is very
the new matrix whilst installing it. Leave it to a specialist....cost to repair approx 120.
