AnswerDaisy,
Your heatercore is located under the dash, behind the centre console. Check with your local dealer, and see if it is covered by a recall. It's a very big job,if it isn't, but if you're up to it here's a check list of how I do it.
1. Remove the heater hoses, under the hood at the firewall
2. Remove two nuts under heater hoses.
3. Loosen third nut behind throttle(if you have A/C.
4. Remove centre console, shelves under steering wheel and glovebox. Centre air vent, air duct to that vent, and bottom rear duct (screw beside gas peddle and at passenger side.
5. Disconnect three heater cables at heater box.
6. With a long phillips screwdriver remove upper air duct.
7. Remove the clips (6 or 8)splitting the heater box vertically into left and right. There are two tough ones at the back, inserting a flat screwdriver and twisting releases them. Practice on the front ones, that are visible
8. Remove the left half that contains the heater core.
Changing heater cores isn't easy, but there was a recall years ago, and we got it down to less than half an hour... after a lot of practice! Good Luck!
P.S You might want to put down some towels and a piece of cardboard on the passanger floor to stay dry. Removing the passanger seat may make it a little easier as well.
Good Luck,
Paul
