My first suspect would be that you either bought a defective thermostat, or you did something wrong when you installed it. This is assuming that the problem didn't begin until after you replaced the thermostat.
If it was a problem which existed prior, I'd take a look at the heater core. It'll be in the same compartment in the duct system as your air conditioning evaporator, usually placed by the vent next to the passenger door. Yes, unfortunately this requires disassembling the dash. Before you go this route, you may want to ensure that there isn't any blockage in your upper and lower heater hoses.
