I own a 2004 s40 T5 and I've had some major problems this past month due to the errors of the service center. What happened was that the heating core pipe was cracked and there was a hole in the radiator (I'm blaming the service center because they didn't catch that and/or they broke it). Because those 2 parts were broken, antifreeze was leaking through the air vent system and fogging up the front window. Beware of this if you're experiencing the window fogging up for no reason. I took the car to my friend's shop. The end result: I needed to replace the heating core and the radiator on the car as well as put in more antifreeze.

I just got the car back today and tried the heating, but for some reason it's not working and cold air keeps coming out. Before I panic and annoy my friend again, I want to know if it's possible that this is just a temporary problem because new antifreeze was poured in. Any helpful feedback would be much appreciated!

 

You might have a bad thermostat which should have been replaced with all the parts that were just installed.

 

would that really do it? I also noticed later on that the light behind the thermostat was out. I took off that panel and I checked to see, sure enough the light was blown out too. Thanks for the feedback. I'll run it by the mechanic when I bring it back to him.

 

The thermostat that Tech is referring to is the one on the engine block that controls the flow of coolant. This is not a part of the climate control unit in the dash.
