My heater doesn't work!!!
I'm about done repairing my car after getting into an accident. Just need a new hood and to get the body parts painted. I can finally start driving it again now that I got the radiator back into place. However, I noticed my heater is not working. So I decided to put the temp to "HI" and fan to full and all it does is blow cool air out. 10 minutes later and cool air is still coming out. Any idea what is wrong and what I should check before having to visit the dealer about this?

The heater is the engine. If the engine doesn't have enough time to get warm, then heat won't come out of the vents.
Now if you actually had a problem, the first thing to do is to check the heater core. There's one line of coolant going into the heater core, and one going out. Check to see if both are warm, and go from there. Sometimes, it's the switch in the dash to flip the valve from cool to hot.
Anyway, you have to warm up the engine before you can make a conclusion as to whether or not the heat works.

This happened to me last year.. and it turned out to be I was low on coolant... once I filled that up, the heater started working perfect! Not sure if this would help your situation.. but just a thought

But at least the heater works now, even with a cold start, it just takes 15 seconds for hot air to come out.
