#274 of 286 Lights out by oldfordmech Sep 03, 2009 (5:22 pm)
Hi jonoor;   OK, it's been awhile but I may be able to help. To test your bulbs use an ohm meter.( you can find a small-cheap volt-amp--ohm tester at Sears, Auto Zone, or anyplace like this ) see if you can pass current through each bulb with your ohm tester, if you don't get a reading you have a bad bulb. Now back to wet lic plate bulbs. Are the sockets clean (with bulb removed) or corroded ? they must be clean. as for water getting in, it can come in around trunk handle, around light lens. take out the lic lifht bulbs and see if other lights work. FLASHBACK I was working at a Ford dealer in 99-00 and we had a recall on 00 Focus to replace the wiring loom that goes to yhe lic lights,they would short out & cause havic. The connector is located in the trunk, on the L.side high up under the back glass. unplug it there and see if you can get your other lights working. If they work with that loom disconnected, go to a Ford dealer and see if this recall is outstanding.If it has been done. Thank them and see if you can find 1 at a bone yard.Get a 4 ft chunk of mechanics wire, take your old loom loose in the trunk, hook the wire to the old loom and pull it out from the L top corner of trunk lid. Tape wire to new loom, spray down with soap water and pull back through trunk lid with mech wire and reconnect to connector. hope this helps. Cliff
#275 of 286 Electrical problems - Central timing module? by mike_be Sep 06, 2009 (1:05 pm)
I have a Ford Focus Ghia Estate 1989CC V reg (2000) which all of a sudden   developed electrical faults as follows: rear and number plate lights don't work   at all; parking lights and side lights don't come on when the light switch is   moved to their respective position; the warning buzzer that sounds when the   lights are left switch on doesn't sound; and the instrument panel illumination   doesn't come on. All the other lights work OK (headlamps -low and high beam-,   indicators, break, fog and reverse lights, interior lights) and the screen wipers   work OK (including intermittent mode). The horn works OK and all the warning   lights in the instrument panel come up as expected. The fuses appear to be OK   in both the engine fuse box and the central fuse box. Any ideas?
#276 of 286 2001 Ford Focus SE Brake lights by brattish Sep 11, 2009 (11:17 am)
have a 2001 Ford Focus SE Manual Transmission. The brake lights don't work yet the fuse, brake switch, flashers and running lights funtion properly. What could be the cause of the brake lights not functioning? I did check the power to the brake switch, the switch is good.   What could be the problem?   Thanks in advance, Dave
#277 of 286 brake lights by oldfordmech Sep 11, 2009 (1:34 pm)
Do your brake lights & flashers use the same bulb ? I've slept since then. If they do, your brake lights go through your turn-signal switch. check for power from brake light sw going up into ts sw & back out to the rear. Hope this helps Cliff

Replying to: rinse (Jul 13, 2009 8:22 pm) I'm curious to know if you found out the problem. I've a 2001 focus that is doing the same thing and I'm thinking it's the starter. I hope not though as the starter looks like a bear to get off.
#279 of 286 no crank by oldfordmech Oct 10, 2009 (10:32 am)
TO TEST THIS get a cheap digital volt meter, test battery voltage, should be about 12.5 or better. next make sure BOTH ends of battery cables are CLEAN & TIGHT. Next have another person turn key to start pos while you read for 12 volts at small wire at starter relay. this relay may be mounted to the inner fender well or it may be mounted to the starter.If you have 12 volts on big red cable at the starter and the small wire has 12 volts with key in start pos, and nothing happens, replace starter. If no voltage on small wire, this could be 1. ign switch 2. neutral start switch if auto trans or 3. clutch depress switch if standard shift. Hope this helps. Cliff.
#280 of 286 Door ajar light stays on by grbeck Oct 24, 2009 (11:06 am)
Our 2005 Focus SE sedan has 97,000 miles on the odometer. Recently the door ajar light on the dashboard has been staying permanently lit, even after we make sure all of the doors are shut. The car is scheduled to go in for service this coming Monday, but we don't want to mention this to the service people until we have an idea of what is causing it. Thank you.
#282 of 286 DOOR AJAR by oldfordmech Oct 24, 2009 (1:12 pm)
You have a small switch that attaches to each door latch, it could be ft. or back if 4 dr. this switch has a plunger that is not returning all the way out when door is closed. This switch was available for 2000 modles so I would think it still should be for 2005. Sometimes they could be an SOB to replace, getting your hand at the right angle and still be able to turn it to get it out and then reverse. It goes into a mounting hole in the latch then you must turn it to lock it in. If it;s a 4 dr. a computer scanner can tell you which door latch is the bad one. Hope this helps, Cliff
