2.0 GL - When I turn the heater onto warm smoke (heavy steam) blows out throught he vents.

Is this a faulty heater matrix or can anyone suggest another likely cause?

If it is the heater matrix how easy are they to change?

Thanks in advance

 

Sounds like your heater matrix has gone. is the smoke out of vents a bit oily.
Dash out job im afraid dont think its that hard a job just time consuming

Thanks for the reply.

Its not oily nor does it seem to smell like antifreeze.

I have now read a separate thread re changing the matrix, it does seem a pain!

 

Have changed a few on other makes but i got to admit when mine went on my wrx i shipped the work out to subaru4you in newbury done a good job too but it did cost a bit.
must be the matrix cant think of any thing else that would cause it
