What’s the worst time for your car, truck or van to stop warming you up on those long trips home to see the family… winter. Winter is the worst time to do anything and have your car not working up to your needs. Today at Dignity Auto Repairs and Services we are doing a heater core on a GMC Jimmy. The heater core was leaking and the seals became lose making the car not produce heat. I have two pictures showing you the core its self and where it’s located in this vehicle. To get the core out you have to remove the front of the dash and unhook the attachments in the engine bay. Then pull the heater core threw the box from th inside of the vehicle. If you have any questions lets us know we will be happy to answer them.
