Vauxhall Vectra heater matrix

2006 Vauxhall Vectra Problem

The Problem:

There is moisture in the passenger footwell and I suspect it is something to do with the heater matrix leaking but am not sure. The water level seems to be OK although I have had to top up some 3-4 months ago. The only other (perhaps related) problem is the temp gauge is very erratic-sometimes shows normal, sometimes no show at all and sometimes in between! No apparent overheating or other problems with heater not working etc.

Any thoughts gratefully received.
Also does the replacement of the heater matrix require the whole dash to be removed?

Thatís right, I've got a Vectra SRi CDTi. I've only had it what 3 months now, and when I was washing it I always lift the bonnet and clean away any leaves, and couldnít help but notice there was water sat under there, so I pulled the rubber strip, lifted were the water comes off the windscreen, and the rubber drain plugs was blocked with leaves. I ain't no mechanic, but if the water does not get out, it will go right in the heater and into the car on the passenger side. So my advice is to keep them clean and free from leaves.

Unlikely to be coolant if as you say ,it was 3/4 months ago when you had to last top up .
