Heaters

[Danger200]

Not entirely sure if this is in the right section or not, but after putting my blowers on this morning to clear my windscreen I noticed a damp smell coming from them (when on hot and cold) and the same goes for when the air con is on.
Everything is working fine and they are getting to the right temps ok but the smell wasn't there when I first got it, is this down to a damp filter or anything?

Cheers for your help

Check your water level mate.

I'm not sure how it works on Civics but it may be a dodgy heater matrix?

I thought that was down to if it doesn't get hot? As there was an air block on my gf's mum system and her car didn't heat up.
But I did just check to be sure and it was all fine. Although I do have to buy a special coolant from Honda apparently as normal coolant cocks it up, maybe that needs changing?
