SOURCE: lexus heater blows cold
You could have a blocked heater core. Check for two heater hoses running into the firewall in the back of your engine. They should be together and about 5/8" in diaameter. If one is hot and the other is cooler then your heater core is blocked. Unhook both hoses and use a garden hose to back flush. Be sure to catch the coolant and dispose of it properly.
