Make Sure the Current is Reaching the Defogger
Locate the Fuse Box to the left of the steering column on earlier models. After 2001, the fuse box is on the passenger side. Open the box by lifting up on the latch, then pulling the door straight out. Remove the defogger fuse from the fuse box using the tool provided. Hold the fuse up to the light to check if it is broken and if so, replace it.
