If the blower is not working on all speeds, you could look at replacing the Blower Motor Resister.
If the blower works on all speeds (including MAX), then it is most likely the Heater Core.
Is there any evidence of fluid or moisture on the passanger side under the glove box, dash, or on the carpet up on the firewall?Pavement sucks... :grrrrrr:

Nope. no moisture at all. Ive also heard that the lines going through the fire wall could be air locked or even possibly the coolant is low. have you heard of that? i personally figured it would be the heater core too. but i thought id ask about any other ideas. maybe even the thermostat is shot?

how does your anti freeze look? I once bought a truck that un be know to me had some really dirty looking anti freeze, turned out to be a radiator stop leak some sneeky bastard had put in the truck. long story short that crap had pluged the heater core, I took the heater lines off and blew air threw them until they got unplugged. worked fine after that. oh and if the anti freeze is really dirty Id recommend flushing out the system wheen you blow out the heater core.2000 Silverado Z71 Whipple Supercharger, JBA Headers,3" cat back Flowmaster Exhaust, Volant cai, Pioneer Preimer deck,Orion subwoofer,03 signal light mirrors,03 taililghts

i would try back flushing the heater core,
take the heater hoses off at the firewall
spray compressed air through not to much pressure tho you car rupture the heater core
take the garden hose with a spray nozzle and fill her back up
