You can go to the Dealer for the part. It is located on the pass side of the engine block. How do you know it is bad? The element does not usually go bad, the cord does. You can check the resistance with a ohm (A good element measures about 11 ohms).Does anybody know where to get replacement block heaters? If so, how much? Also, where in the devil is this thing located???? Mine is bad and needs to be replaced.
