Hello I am a first time poster. I have a 2005 SE ZX4. Problem is I have no brake lights, turn signals or hazard lights. I have already checked the fuses and there were 3 blown. Cig lighter, GEM turn signals, and liftgate release. Not too worried about the cig lighter. But have already taken off the hazard button and turn signal switch and the fuse still blew. Also disconnected head lights with same results. Also inspected rear lights and bulbs. Their is still a clicking sound when you activate the turn signals and hazards just no lights. Also, the tail lights work when the headlamps are lit. Any help would be appreciated.

Hello, welcome to FF.

That is a somewhat common problem in Focus hatchback cars.

Inspect and repair the wiring inside the rubber umbilical sleeve, located in the back, between the hatch door and car body.

Whoops, I thought you had a hatchback, then saw after my post you have a ZX4, a sedan, right?

The same problem can happen in the sedan, but is not near as common, nor as severe as you described. Sedan or hatchback, check the umbilical wiring first.

Yeah, with a sedan, I can't imagine that problem (3 fuses blown) could be faulty rear umbilical wiring.

Maybe the cig lighter fuse blew-up before the other two? -and was a separate event. Did you replace the cig lighter fuse, and did the fuse blow a second time? THAT would be very strange if it blew-up again... assuming you are not currently using the cig lighter socket to charge a defective item.

Any chance you or a previous owner tapped into the cig lighter circuit to power an added widget? -aftermarket lighting or stereo?

The obvious guess is that some wiring (somewhere) is damaged and should be a black & burned mess. A slow visual inspection of any/all exposed wiring would be one of my first steps; inside the engine bay and under the dash.

Second step = multimeter testing. This would prove the electrical short/s, and help in the physical search.

Yes there is definitely a short in the cig lighter as I put in a new fuse and it blew when I pushed the lighter in. The lift gate release fuse did not blow when replaced. Could this GEM have anything to do with it?

Gotta be careful, with exact info, as this goes forward...

"pushed the lighter in"

The cig lighter circuit is usually stand-alone, and it provides power to nothing else. This fuse should not blow unless the socket or circuit wiring is messed-up, -aka shorted. So I guess, you are you using the cig lighter glow-plug to get it red-hot, and light a cigarette, right? IF YES, please do not use that glow-plug again. Next: replace the fuse, THEN see if the fuse blows-up again without using the cig lighter port.

If the fuse does NOT blow-up while you are NOT using the port, then you can kinda-sorta believe that the cig lighter circuit-wiring is OK. After that, please try using a phone-charger in the cig lighter port (or any similar low power device); does this work? -and does this NOT blow the fuse? Later, try a different cig lighter glow-plug. Does this new/different glow-plug also blow-up the cig lighter fuse when you push it in?

I have other comments and questions, but I have some family stuff going on atm. CU later or tomorrow.

The other circuits, the other fuses, are not on my mind atm. I do not think your GEM is faulty. Also, the GEM has nothing to do with the cig lighter.

Which fuses are currently blowing-up, while NOT using the cig lighter. Stop using the cig lighter port until other things are sorted out.

Found a piece of metal shorting out cig lighter in socket. Part of an old adaptor or something. Well that is fixed. Now on to the main problems. Thanks for your input Marde.

Good catch, good fix.

I think the "liftgate release" fuse that you replaced will blow again in the near future. This might be tied into the other problem; your "GEM turn signals" fuse is still blowing-up right? What are these two fuse numbers?

I have wire diagrams for the 2004, and not for the 2005, so I can't give you hard facts for your 2005.

Please inspect the wiring inside the trunk rubber umbilical.

Also, there are two electrical connectors behind the panels inside the trunk, on the left side (drivers side) that contain some of the wiring for both liftgate release & turn signals. You might need to get inside this area for inspections or repair work... TBD. Oh, BTW, you might want to disconnect these connectors as a test. With these 2 connectors disconnected, see if the GEM turn signals fuse blows-up or not. edit: during this test, operate-exercise the trunk release and the turn signals.

The GEM turn signal fuse is #32 and the liftgate release is #37. And the GEM fuse is still blowing. I even disconnected the brake light switch(es) and the fuse still blew. But I will inspect the trunk area even better than I have as I think this is where the short is. Thanks again Marde.

Sorry for talking about the 2004, but I was doing a comparison between your 05 verses my 04. Some of this is me talking out loud...

The GEM turn signal fuse is #32 and the liftgate release is #37...
Yeah, based on your descriptions, and my 2004 wire diagrams, there are some unique differences between the 2004 vs 2005 with these 2 systems.

Both 04 and 05 share fuse-32 as GEM power. The 04 wire diagrams name this fuse as GEM, while the 04 owners manual calls it "turn signals". Both 04 and 05 use fuse-32, it is for the GEM, which controls the turn signals. "GEM turn signals" is clearly the best name.

2004 does not have a fuse for the liftgate (between the GEM and liftgate latch) so I will assume my fuse-32 would blow if my car had a short in the wiring between the GEM and liftgate release latch.

Ah crap. I just found page 117-6 in the 2004 wire diagrams called "Sedan, Late Production". This shows me how (some 04 sedan are wired) your 2005 sedan is wired. It includes fuse-37. I am not going to attempt to explain this diagram, but here is the summary...

Your Sedan has 1 (and sometimes 2) always HOT (aka voltage-hot) wires are running in the trunk area; likely thru the rubber umbilical mentioned earlier. This can and will blow-up fuses when the wiring is messed up back there.

Inspect that wiring, inside the umbilical, very-very carefully.

Good luck

P.S. - I now remember running into this exact thing once before. Not too long ago. Learn. Forget. Re-learn. Rinse, repeat.

Well as I suspected the short was in the trunk. Took the plastic cover off where the wiring harness crosses over to the passenger side turn signals and there was the culprit. Wires that were smashed and fused together. Much appreciation to Marde for his help all the way through this process.

Please post again. I am unsure where you found the wiring problem. Please explain the exact location of the culprit?

Underneath the plastic black cover by the opening of the trunk on the drivers side, the wires for the turn signals go from the driver to the passenger side turn signals. In between the wires were shorted together. Open your trunk and look straight down. You will see a plastic black cover going from one side to the other. Held on by plastic push pin screws. I don't know if the hatches are the same though? Thanks again for all your help.

Thanks for the added details. Always good to see any thread closed with a fixed car.

My trunk space is a little different than yours, -mine is a wagon.

Cheers!

Hi! Very new here! I’m on my own now, and I need to fix my car. This thread has helped me so far. I know what to check now! I have a 2005 ZXW (wagon), it’s my third, and I love them sooo much! I know to check the wiring in the hatch, would that be the only place to check? I know to disconnect the battery, but wiring diagrams are very confusing. I’m a left brainer, and would appreciate any directions, you tube tutorials, etc. I have a young son, and rely heavily on this car - no extra money to take it in to be fixed. I’m not a complete idiot...lol, just new. ✌�� I will be going to check the wiring in the hatch. It did look sketchy the last time I examined it (a year ago)??
