just found where water was leaking is it an easy fix what they called and get u get new 1s

where these go on 2

 

looks like the heater matrix

 

its the heater matrix as above...

 

thats the heater matrix need to change it and to do that the dashboard has to come out...you should be able to get a second hand heater matrix easy enough

 

thanks for the replys is it a hard/big job

 

As above heater matrix, you'll need to remove the lower half of the dash along with all the heating ducts. Then you'll need to undo the two nuts holding the heater unit to the underside of the bulkhead. ONnce you've got that far you can then pull the unit out far enough to get the matrix out.
