Re: "EAC Fail" on 2003 Fiesta Ghia 1.4
I agree that for a wiring loom to be damaged already means it must have been badly fitted. The stupid thing is that the only wires it could possibly have a fault in are as follows:
the throttle body to a loom
that loom to the PCM (or ECU if you want to call it that)
the PCM to another wiring loom
that wiring loom to the throttle pedal
Absolutely no other part of the wiring system is involved in the EAC; I know because my brother has a copy of the 10 page document Ford were using on my car. It shows the wiring system for this circuit and those are the only wires. I refuse to believe you need the entire wiring system replaced and as my brother pointed out, the wiring system in the car is the single most expensive part since there's so much copper. I would suggest you ask your garage to change only the parts associated with the EAC.
If doing that doesn't fix the problem, there is no reason why you should be paying for it. At the end of the day, you're not asking them to replace specific things, Ford are telling you and them that this is what needs replacing to fix your issue. Ford should definitely be responsible for any lack of fix this work supplies.
As I said before, I've paid £620 to get my PCM changed and the fault still hasn't recurred after having done nearly 200 miles. It was happening daily to my car after Ford started changing parts that didn't need changing. It happened when starting the engine sometimes, it happened when first pulling away and when driving at 65MPH one time, which I can sympathise with you about how scary and dangerous that is because the guy behind me was flashing and beeping as my car rapidly approached 30MPH on a motorway before holding at 30 and not letting me accelerate.
When I say that they only have to recall safety issues, again I agree that they should recall this, but as I explained before, although this can land you in a dangerous situation like the one above, it isn't classed as a safety issue. Safety issues are ones which compromise your safety in the event of an accident; not those which make you more likely to have that accident. I don't want to be on Ford's side regarding this, but that's the facts and there's little we can do to change that.
I would suggest you make a stinking fuss with Ford about this because I suspect if they're going to do the wiring for free, they will want to do it themselves. I doubt they'll pay a third party garage to do the work nor reimburse you if you choose to get that third party garage to do it at your expense. Ford were surprisingly reasonable about the cost after much complaining to their service manager, but they don't offer customer service on first approach in my experience. You need to make sure they know you by name. Trust me; when I came back for the final time to pick up the car, the first thing they said was "Hello, Mr. McHattie. How are you today?" which is the first time they've recognised me without having to ask my name first. Give them hell!!
