To begin, if you have A/C, you're screwed. You HAVE to take it into a shop cause the system has to be discharged. Otherwise: pretty much you need to take apart the entire dash. Well, the lower portion anyways. Take all the cover panels off, then take out the center console, and the plastic around your shifter. After that, take out the metal supports for the dash. Then take the duct between the fan (far right) and the heater unit (center) out. Now, you're left with the heater unit which is in the center. Go under the hood and around that center area you'll see two hoses coming out of the firewall. Drain the radiator, and then disconnect those two hoses. Now you can take out the heater unit. Inside the unit is the heater core. In order to install, just do the reverse. Hope this helps.

No heat coming out on windshield defroster


First thing to do is check your coolant level. If its low the first thing to starve is the heater core. Then feel your heater hoses when its warmed up. They should both be warm. If only one is warm its the heat control valve that isn't working. If they are both cold you may need a water pump. Hard to tell from here.

No heat/defrost 01 corolla


Sounds like you have air trapped in the heater core when you flushed the heater core. loosen the upper most heater core hose and run the engine untill coolant seeps out. Wait until the coolant has reached running temperature.
