Here's the thing I don't drive the z in the winter so I really don't use the heater that often. But I noticed some furry little bastards (mice)making a nest on the lt1. Now I get no heat when I crank it up. If i leave it on low I can feel a little heat from the vents. So is my heater core blocked or do I have another problem. It figures that I just replaced the carpet (tan) In the summer.

They might have a nest blocking heat. Or chewed up hoses. Why do you let rats in anyway lol....

Try flushing the heater core both ways...common problem...gunk tends to build up in there cause DEXCOOL sucks.
