Rear window defogger quit working


Asked by GuruGary Jan 24, 2013 at 09:50 AM about the 2008 Chevrolet Impala LS FWD

Question type: Maintenance & Repair

The rear window defogger does not work on my 2008 Chev Impala.  Just stopped one day.  The owner's manual says nothing in the fuse diagram about a fuse for that particular circuit.  I had just assumed that was it.  Help?

There is a little fuse at the underhood fuse box. The grey boxes are relays and there is a silver box to check which is a circuit breaker. Just wiggle them out to remove them. Use a fuse puller, sometimes there is one clipped to the fuse box, pliers could break the plastic then you have a mess, you would have to get the prongs out. Check the underhood fuse block-look for 'RT I/P #3'-this fuse controls the rear defogger. There is also a circuit breaker at the right side fuse block in the instrument panel. Open the passenger front door, pull the side dash cover off and look for REAR DEFOG BRKR. You can swap it with the breaker above it to see if it's the breaker that is bad. There is also a REAR DEFOG RELAY to the left of the breaker. Put your finger on it and turn the defogger on and off and see if you can feel it 'clicking'. If you can then the relay should be OK

What causes the connector to burn, and what happens when you fix the problem with a bypass?
