Cigarette Lighter Check

WARNING: This page is about a different car, the 2008 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.

Take out the plug, and check for a worn edge on the element spot connection, and for shreds of tobacco or other material on the element.
Using an ohmmeter, check that the element resistance value is 1.7 ohms.
