Replacement of Heater matrix

[anthonyjg]

The car is 2.8 Tasmin, 'Y' reg., with the 'horizontal' instrument panel. After having had all the water hoses replaced with silicone I suspect that there is a slow leak in the heater matrix. Symptoms are constant misting up, despite the blower being on full and hot, and condensation on the inside of the screen when I come back to the car after a few minutes.

Steve Heath is not very specific about removing the dashboard, but it seems that you have first to remove the padded trim, then undo many tiny nuts holding the veneer in place, followed by the instrument panel itself. After that you should be able to get at the heater matrix box and undertake surgery on it.

Hhs anybody actually done this and, if so, please can you help with any tips? Many thanks.

Thanks for your replies. After having read them I am inclined to leave it for a few weeks, until the weather warms up a bit before tackling it. Also I will try and get a spare heater matrix lined up ready to go in, as I suspect that reconditioning the old one will not be an "off the shelf" job! I don't think it is just an airlock (wish it was), as the air coming out of the windscreen vents is warm and steamy, not cold and steamy. I will post the results, as and when done.
