I have a 2005 Ford Focus ZX3. It has about 107k miles. I have been having electrical problems for about 6 months. It started with a clicking sound from the driver side under dash and the radio resetting back to am and 12:00 after it sits for a while. It sounds like a relay clicking in fuse box. It started maybe once a month. Now its getting worse with other symptoms. When I here the clicking noise the lights will flicker. Sometimes when I get into the car to start it I have no power at all. No interior light no head lights nothing. When I try to start the car it will do nothing. I have no power at all. When I finally get it started the radio has reset back to AM and 12:00. I have tried switching the power saver relay out and checked all fuses. I also checked the battery connections. This did not help at all. Also when I have the Cruise Control on and it does this the car will buck.
