Don't be sorry you come from Canada. I do too.

I set my heater between 26 and 28 when it gets really cold out. When you set it to 32, do you get a lot of heat?

The two links I provided in an earlier response to you have a lot of information related to your HVAC system. Go through those links and see if anything in your car looks as though it is not functioning as it should.

If it was that bad you should pull the windscreen cowl vent off so you can clean that area out properly. It is not difficult to remove and replace it.

Well today I found a heated shop to check out the air actuator. I pulled the glove box and took off the cover under glovebox, I looked in and saw a mind boggling sight. I found what I think is the air actuator a small box looking thing with a shaft on top with a threaded rod going toward the drivers side mounted to another arm .I tried pushing the rod each way with no movement. Then I started the engine and pushed the temp button and watched the rod. It moved very slowly in one direction then I pushed the temp button to change the temp the rod moved in the oposite direction with no stoppage. When I first saw the rod it had a fairly large looking hose rubbing on the rod so I reposioned the hose . Is this the way the air actuator suposed to work can it be taken apart and lubed. thanks
