Rear defroster switch

My rear defroster isn't working. When I go to press the button I hear a clicking in down where the fuse box is. SO, i pull it out and check fuses. Run to AutoZone, buy a relay, doesn't seem to be working. HELP! Does anyone know what's going on?

According to the 2000 Focus Owner's Manual, The rear defroster is fuse # 49, 25 Amp, and relay # 25 in the passenger compartment fuse/relay panel. Check/double check the fuse, if you have a meter use it to check fuse. If fuse is good then swap relay with know good one. When removing fuse and relay check the socket that they plug into. If this is a wagon or hatchback check the wiring that runs into hatch for chafing, breakage, cuts, ect. These wires are known to breakdown over years due to repeated bending due to opening/closing hatch. Also if you have a meter check for check for voltage at the rear defroster and switch for voltage.

Good Luck.

Thanks so much. But if the rear defroster relay is located on the passenger side, why is the clicking coming from driver side (fuse box)?

When the manual says passanger it means the interior compartment. Not meaning from the passanger side of the car. Its in the Fuse box next to your left foot.

Thats normal and should do that. It means that the when you push the switch it actuates the relay (click) and sends power to the back of the car to heat the window up. Have you done any window tint install or removal recently? using a razor blade and not being careful will cut the defroster lines and make them not work.

Nope. Nothing. When I test the relay/s I disconnected the negative battery terminal, pulled fuse box down so I get gain access to the relays and started swapping them out, while with each one I reconnecting the battery. Put the key in the "ON" position, hit the rear defrost button and still clicks. Getting annoyed with it especially living here in Cleveland, OH. Humid as hell right now.

Do you have a meter that you can use to check the voltage at the rear window. Also look for small breaks in the foil as this will "Break" the circuit. If the relay is clicking then the switch should be ok. Do you have a Wagon or hatchback? If so check your wiring that runs into gate/hatch for chafing, breaks, cuts, ect.

Your problem is after the relay something close to the window is at fault

I have the ZTS so it's the sedan. I looked for breaks in the wiring but didn't see anything. Yeah, a buddy of mine says it's probably something AFTER the relay maybe even somewhere in the door.
