i also have this issue, any news?

It is the heater matrix in the dash, the passenger pipes are vertical and drivers horizontal apparently and this causes the passenger side to block. Last year i removed the 2 hoses where they go through the baulkhead filled it with radflush and then run the hose through it both ways for some time, this cured it for 6 months but now i have the same problem back again. It is such a pain would not mind if other way round but my wife hates the cold and i have to cokk myself to wram her side of car up.

Kind regards

Russell.

I got the same problem as well. I posted about it a while back but had no replies. So Russell, what you did was it an easy fix? Is this a dash out fix or something? There must be a proper fix though but it just doesnt make sense. My car is a 2002 car and had no issues but then this just started randomly last year.

Not a dash out job, the pipes are accessable just before they go thorugh the bulkhead from the engine. Un clip from there and then do as aboce with a hose and some rad flush

[lex2oos]

yup, I had the same problem. flushed heater matrix with garden hose in both ways several times. now it is good.

[reganlives]

Is the heater matrix linked to the rad? So basically its the actual matrix that is flushed so attach pipes to the holes in the bulkhead and dont touch the pipes that you remove as they get put back on later? Could do with some pics and a guide please...
