once you get behind the glove box and can see the heater core, get a screw driver, wedge, and break. I'm serious, its the same way with VWs. they use an apoxy to keep the core from rattling. just make sure you don't go overboard and break everything around the core. Rubbish this will do nothing but damage!! The correct procedure is 1.Remove the rear section of the centre console covering the park brake lever 2. Remove passengers seat. 3. Remove glovebox 4.Remove centre console. 4.Disconncect heaterbox control cables. 5.Remove heater controls panel 6.Remove steering wheel. 7. Remove instrument facia panel 8.Remove instrument cluster 9.Remove dash end panels left & right side. 10. Remove screw cover in the center of the dash next to the windscreen 11. Remove two securing bolts at each end of the dash inside the access covers, remove screw at center dash area. 12. disconnect round air distribution tubes at each side. 13. unclip wiring from dash where required. 14. pull complete dash away from windscreen at towards rear of car. 15. disconnect remaining electrical connectors as space permits. 16. disconnect heater hoses from in the engine bay 17. Unbolt heater box from firewall manouver a/c box off studs if required. 18. remove heater box from car 19. remove four screws holding heater core in to the heaterbox. 2. remove old heater core and replace with new unit. Revesre the order and the car will be back together all fixed with no damage.
