when you say the temp guage is fine.....does it come up to normal running temp?
in the mean time, turn on the a/c and turn the temp knob over to warm, or as far to the right as possible. this will give ya heat. ive the used the a/c for heat on my 95 S-10 since it was new, and it gives heat faster than the heater ever will.

All you need to do to flush the heater core is to remove both heater hoses and back flush the heater core using a garden hose (not too much pressure though). This is a pretty common problem. I just had to flush mine out yesterday. I would recommend buying a prestone flush and fill kit because the same thing is happening in your radiator. You can get them at the autoparts store. You guys also might want to go back and read a post on January of 2003 from bowtiebandit (heater core clogging). He had a lot of good information on the problem and how to fix it. He goes into a lot of detail that is pretty easy to follow.
