steam coming out would indicate a leak with the heater matrix.

sorry to say I agree with scoobyricht it sounds like heater matrix, i had the same last year due to a lack of anti freeze. Dash out job

Dash out You lucky man!

Done mine not so long back.




My windscreen would mist up so I bypassed the matrix for a while untill I could be bothered to do it. That was in the summer, wouldn't fancy no heaters this time of year. Brrrrr!

it was working fine until i put more anti freeze and forgot to put the expantion tank top back on.

Can you smell the antifreeze in the car when things are starting to mist up? I could.
I then checked the passenger footwell. It wasn't wet but just a little damp right up by the bulkhead.

johng5

can smell it antifreeze but no wet or dampness anybody got a idea how much id cost to get it fixed

I had a good 2nd hand unit for a tenner and changed it myself. You're looking at a day to get it done. It's not that bad a job, just a pain in the ****.
Didn't price new ones so can't help you there.

New from a main dealer they are around £250. I could not source a non OEM part so had to buy from a Subaru dealer for my 1999 classic.
Staggering price for something about 20cms square with a couple of pipes attached.
Local garage took about five hours to change it as the dash had to be removed. All in bill around £500.
