Heater matrix location and part number

[krio1987]

I have a Citroen C4 Grand Picasso mk 2, 66 plate. I have discovered my front passenger foot well is soaking wet.
This happened on my old mk1 grand Picasso and it turned out that the heater matrix had blown.

It makes sense since the heating hasn’t been operating as efficiently recently.

Would anybody be able to provide the location and part number for it so I can investigate a the cost of a replacement and check that it is intact blown,

Many thanks

The matrix is accessible from the passenger foot well - they are common for blocking up (usually lose the heating on the driver's side first). Changing it (on a RHD car) is reasonably straightforward as the dash doesn't need to come out - by all accounts getting the pipe clips back on and water tight is the hardest bit. DK Motors in Boston are specialists in these, and offer an updated matrix that should be less prone to blocking up.

Thanks for coming back Richard, sounds like its the same process I had on my last car.
Do you have a link handy for DK motors to hand?

Many thanks
