The Itty Bitty NOVA VW Committee

So.... This car can't stay warm. If I put the heat in anything above 2/6, the temp will work it's way back to zero. It will get up to temp if I don't run the heat, but in anything colder than 40 degrees ambient, using the heat slowly brings it back down from 195 to zero. I've been observing this for weeks now. I've never had a car struggle to stay warm like this. Is it normal?


The car was at 195 after 5 minutes of running and I turned on the heat full blast which dropped it right back down to 140.
Sitting in traffic. The heat is on 3/6 and the car has been running for 17 minutes according to the dash and the temp just now peaked over 170. It's 21 degrees outside. No wind.

I figure a bad thermostat, it wouldn't ever warm up at all, but it warms up just fine with the heat off.

I expect the 190-170 fluctuation to MAYBE be because it's a real gauge and not buffered, so please don't flame me there. Perhaps it's my short, stop and go commute. I always figured the car gets hotter when it isn't moving.
