2003 Lincoln Navigator Question: Remove Heater Core
There's a Technical Service Bulletin on the heater core for this vehicle. TSB # 06-21-19. Yes the dash has to come out or lifted up so you can remove the HVAC assy. You can do this yourself with the proper detailed instructions. Spend $26.95 for detailed instructions from www.alldatadiy.com. You then will also be able to read the TSB also. - backyard tech
