Title: Heating issue
Post by: JamesV6CDX on 09 December 2020, 22:03:24
2003 2.6 Elite.

Problem getting heat in the cabin.

Engine coolant is getting up to temp, according to the temp gauge and CTS readings.

Inside the cabin, when I put the heat to blow on the screen, it's cold. When I direct it at my feet, it's cold, even on "hi". When I direct it at my face - the left hand vent ( in the centre bit) is warm(ish), the one right next to it blows cold air. The vent on the far right, blows stone cold.

Only had a quick look, but all the vacuum pipes look ok, undamaged, correctly routed, and in order.

Any ideas? Not had a look on the "tool" at any climate codes yet. I recall from times gone by there's some sort of "climate reset" - would that help?

Never come across this before! I think it's a problem with the vacuum operated flaps etc, but, I can't see any issues.

Also don't think it's the matrix, else why would one vent blow warm, and the one next to it stone cold!

Cheers,
James

Can be heater matrix problem. When my started to block I did not get heat to back seats. Then it gradually went worse and finally I had to change the matrix.

If passenger side is good and drivers not (or vice versa) then check the bland flap actuators (info in the maintenance guides)

Else start by flushing the matrix (reverse flush)

Nothing to say that both sides can have the same issue at the same time too ;)

When mine failed, there was no coolant loss, just no heat. £12 ebay special later and it was fixed.

Possibly the first non leaking hbv failure in history... But fair enough  ;)

Heater flap rods detached or motors faulty
