How do I remove the dashboard of 2000 GMC Sierra 1500 to replace the heater core?
WelcomeCustomer HERE is a document that you can print out with instructions and diagrams for the heater core replacement. This is a big job and you will have to get the AC recovered then recharged. Take lots of pictures with a camera and good luck. Please ask if you have any questions.
