I have a 2000 GMC Sierra 1/2 ton. I am not getting any heat in the cab. The engine coolant temp. Gauge reads normal, but I still get no heat in the cab. I have always noticed cold air on the passenger side, but this year there is no heat, is there a vent stuck open

Verify that the thermostat is operating properly
replace if needed
check and verify that heater hoses kinked free and getting hot if not
remove hoses and flush heater core
