lol, calm down he's just messing with you. You might want to get your thermostat changed. Where did you pull that code from btw. Also, I've noticed in my E36, the front facing vents don't get very warm either, just the defrost and foot vents. As for the temp needle, mine starts in the blue and sets in the middle around 2-6 minutes depending on how cold it is that day. But I would start by looking at replacing that thermostat.
