Question about 1990 Toyota Corolla
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.
