I know we had to drop the dash and part of the counsel to get to the heater core in my 92 grand am.. .. It was easy to do, but very time consuming...Good luck!!!

You will need to get to the heater core by removing the lower part of the dash. There are usually several bolts and clips you will need to remove to get the duct work to come apart. The heater core should be easy to reach once you get the bottom of the duct off. Remove the hoses after draining the system. Unbolt the heater core, replace it with a new one and replace everything you took off. Connect the hoses and refill the system. It is a good idea to run the car until it gets hot with the radiator cap off so you can get all the air out of the system. One suggestion, purchase a repair manual to show you exactly how to get to the heater core. It will make everything easier.

One suggestion is to disconnect the battery just incase you have any loose wires. I just changed mine over the weekend and it is time consuming. The book the manuel that I bought was pretty general. Skim through the book before you buy it.

did my nephews on 97 and removed the bottom plastic covers underneath the dash and like gtp dad said theres a few bolts and clips once those are out its pretty simple take heater hoses off behind engine by fire wall and pull old core out put new one in and put all platic covers back on and heater hoses took me a whole saturday to do. very uncomfortable to get under dash.
