Question about 1999 Oldsmobile Bravada
Fan works, engine temp ok, fluids are good, just not getting warm air
Had same problem. Take off both hoses to the heater core at the fire wall. Using a garden hose with nozel flush with water on the "inlet hose" first(the one hot to touch) then flush the other side. A nasty blackish slim will come out. Oh, cover your distributor with a plastic bag first so it won't get wet. Put the hoses back on, set heat for full high and enjoy your nice warm bravada again!

Sounds like the heater core needs to be changed out

Valve is on firewall where the heater hoses enter firewall to heater core! maybe you should pressure flush the system that will slow up heat to!
