Heat, No Heat!

[albertabound]

My heater seems to have a mind of it's own lately. It usually heats up nicely after a few minutes, and I'm good to go. Sometimes it will just blow cold air. It's totally random, happening at night, morning, after I've driven a while with the heat on, stopped, shut the engine off, then get back in a while later. All other functions are normal. It seems like a sticky sensor or thermostat. Has anyone had this problem, and/or know a fix? Thank you in advance.

Does the temp guage fluctuate more than normal? If so, maybe a bad T-stat.
