Ford Focus Electrical and Lighting Problems

  • I have a 04 focus zx3 133,000 mi. when driving the car after it has warmed up the radio will turn off along with dash lights for a sec or two sometimes loss of power to engine. when this happens i can hear a relay clicking up under the left side of dash. also sometimes when trying to start the car there is no power to anything. the alternator is good and battery is new. any help would be appreciated!
  • Drop your steering column down when this happens and check for power coming into switch ( large yellow wire ? ) if ok, you should have 1 or more wires that get power when you yurn the key to start, if no power is found, replace your IGN switch.
    Do this testing with a 12 volt test light.
  • my battery light came on, but I checked the battery and its at an almost full charge and, I've checked all the connections. Now it won't start. :( what could it be?
  • i took my car into the dealership today and they found it was the alternator. it was fluctuating from 14 amps to 8 amps so i will see if it is the cure.
  • I drive a 2004 ford focus zx5 2.0L When I go to turn on the headlights and such when it gets dark, my passenger side tail light and parking light, and the turn signal flasher light will not come on. However if I use the breaks or turn signal to turn right, those lights will light up.When I click on the remote to lock the doors also all the lights light up correctly.
    I have checked the bulbs and the fuses and they all appear to be good. I've checked over the headlight switch and the direction signal switch and they appear to be ok, but its possible I missed something.
    Any ideas on what could be wrong are appreciated!
  • Does your R.side turn signal and brake light work properly ? Your question does not make this clear.
  • Yes, they both work correctly.
  • It sounds like you may have an open ground wire in the harness of that side tail light. Maybe look for a damaged wire where the harness runs into the door of the hatch.
  • has any of the bulbs on the car recently been replaced?
  • Yes, I replaced the tail light (mostly because I thought it was burned out) and I replaced the bulb for the R. side directional light, which was burned out. The parking light bulb was ok as was the tail light, however I left the new bulb in for the tail light anyways.
    I haven't had a chance yet to go over the grounds, however from what I recall, I think they were ok. I will have to check to make sure once I'm off work.
  • use a 12 volt test light, turn pk light on, remove bulb, ground test light to inner surface or where bulb tangs park, then touch pointed end to bulb contact, it should light, if not, move ground clamp to a KNOWN good ground, if it lights then, you have a bad ground.if it doesn't light, you have an open in the power feed side, pos a bad socket. let me know
  • OK it may sound degrading but check the bulbs and compare them with the opposite side. if there is a single filament bulb in a dual filament socket it with cause a short and loss of power to certain components. some bulbs look very similar. You wouldn't believe how often I see this happen being a technician for four different car lines. Let me know what you find.
  • Well, I feel a bit silly, aggravated/frustrated and all those wonderful feelings. Now keep in mind I had previously gone over the fuses. And I had thought I had checked them all. So I either just missed one, or just didn't see it. because the problem turned out to be the fuse. Thank you rchannin and oldfordmech. I really appreciate the suggestions you both have given me. I still don't know how I missed the blown fuse, but somehow I did. I guess I do need my eyes checked or something. Anyways, thanks again.
  • I am having this problem with my 2002 focus se. it sit's for a few day's and its dead as a door nail. I am on my third alternator, new starter and 5th battery. have you figured out what the problem was with your's?
  • I solved the same problem by disconnecting the radio fuses. I guess the radio coils in the focus are known to drain power, especially when it gets cold.

    A mechanic suggested I disconnect the main radio fuse, plus the instrument cluster/radio fuse. However, he told me to put the cluster one back in if I experienced any driving/shifting problems because of the cluster's effect on this. But I've had both fuses out since, and no battery death.
  • What do you mean by taking the fuses out? Take them out when the car sits or take them out for good?
  • you can connect an amp meter up in line on the battery at the highest setting so you dont blow the fuse in the meter, and check the amount of amps being used while the car is off, then then you can remove the fuses one at a time and see if the amps drop drastically after each fuse is pulled. whichever fuse causes the amps to drop thats where the problem is. check the components on that circuit by disconnecting the components on that circuit one at a time with all the fuses in then again whichever causes the drop in amps thats whats causing the problem check the wires and connection before assuming the component is faulty. This is called a parasitic draw test. Sounds like there is something being grounded that shouldn't be when the car is off. You can pick up a cheap amp meter at most parts stores for ten bucks or so.
  • Hi OFM, I just joined edmunds after reading your reply to this problem:

    I have had similar intermittent problems with a 2002 Focus ZX5 where I hear the clicking under the dash, and once turned the car off, and then attempted to turn on - but no power (even radio memory lost). Waited a couple of minutes, then turned motor on, clicking returned but when I turned on headlamps, engine promptly died. Started back up after turning the key. Got home, no clicking no dying when turning lights on. ??????? What's the clicking, etc.
  • I am a newbie on these forums so this may be a double post. Still figuring how to use Edmunds.

    But, I just noticed that my front right bright filament is out in this car. Is this related to the below problem?

  • It sounds like a bad relay in the fuse box panel that is causing the clicking and possibly the electrical malfunction. You can tell which relay it is by touching the top to see if you can feel the click.

    It's has been 1 year and the problem has never came back. It cost zero dollars to fix this issue. Thanks to the old Ford Mechanic.

  • Glad to help, thanks for the feed back
  • help...............my shifter button , would not go in.......I have to do it manually........fuse appears to be fine.............is there a relay.............dealer is trying to sell me a shifter assembly...............HELP!
  • ? are you saying that when you have your brake applied and you try to come out of park you have use a screwdriver through the access hole and hold the paw ouer to get it out of park ? If this is the case,check and see if your brake lights are working. If they work, check to see if you have 12 volts to paw solinoid under shifter cover.If you have 12 V. there I THINK you can get the solinoid by it's self or at a junk yard. Hope this helps.

  • my car ford focus se 2002 cannot start after overnight rest. I changed old battery last november and it happen again. I asked car technician who replace new battery to check again. he said there in no problem after check. When I went to pick up car, it lost power again in his place. I feel some wrong with electricity. electrical leakage by somehow. could some one give me some clues to find out mycar problem?
  • Take your radio fuses out. The radio is probably draining, like mine does in cold weather.

    see when your an adult with kids you need dependability
    another problem with the wonder six disc cd change junk and 600 for new one from ford and o yeah all my cd's were stuck inside nice huh car only had 20,000 miles on it

    guy at ford said they had problems with water coming in the heater inlet and I said "your telling me" started shifting like crap too (automatic trans.) good luck

    I have a 2000 Focus since new. My solution for the battery drain problem was to wrap aluminum foil around the battery post prior to putting the cable on. It solved my connection/battery drain problem except for long periods(more than a week) of inactivity. Focus has numerous battery drain issues. I have read several solutions that have worked for different people. Countless hours and $ spent. If you are on a tight budget you can also install a "battery cutoff switch." They sell it cheapest at "Walmart." It goes on the negative side of the battery. You twist a knob for ON/OFF. The only drawback is items with "memory" may lose their memory. The switch worked perfect on my wifes older car that had a slow battery drain problem. You can use it over night or all the time if you want. Good luck!
  • Many thing can cause batt drain. 1. is the batt KNOWN to be in very good cond.?
    2. if so batt muct be dry and CLEAN, Cables & Posts clean & TIGHT at BOTH ends. 3. If #2 is good, disconnect neg cable, put a digital volt-amp meter between post & cable end, set on the 10 amp setting,key out,doors and ALL lifgts & acc OFF. read meter, if over 0.5 TO 0.75 amp draw, start removing fuses 1 at a time until amp reading falls back, when it does, you have found the bad circuit Repair that circuit and you have repaired your battery draw.
    Hope this helps.

    I have a problem with blowing a fuse for the front electric windows. At first, a fuse would blow ocassionally..now it has progressed to where the fuse blows the instant the power is turn on, even before activating any switches. I have traced the wiring as much as I can see and there is no apparent damage to any wiring. Any ideas?
