A piece of my cell phone charger fell off and got stuck in my cigarette lighter. I used a pen to get it out. Now the cigarette lighter doesn't work. Perhaps I shorted it out? Hoping it's small and inexpensive fix.
How much should it cost to repair the cigarette lighter/power outlet? on 2006 Subaru Impreza Outback Sport
To replace the heater core the dash will have to be disassembled. To by pass it for now you can joint the two hoses in the engine compartment at the firewall so they no longer bring hot engine coolant into the heater core inside the truck.
