rear window defogger

you will probably need to check for power, at the rear window connecting terminal. If you have power to the rear window defroster grid, to be sure you have a good circuit. Most of the time you might has a loose terminal were the wire connects to the glass. Or a small hard to see break in the grid, on the glass. you can check that with a olhm meter by putting one test lead at each end of each line across the glass. If any show a break it the circuit you will need to repair that row. Kits are avalible at auto parts store for this purpose cheap! If your fusesand relays are ok and you have no power at rear window check the switch.
