The switch was not the issue by the looks of it, Ford are sending an engineer to the dealer, as, they have another car there with the same issue at the moment. Could be a software issue?So what is the matter with this switch, that it does not keep working right?
Does it last a few days then just pack in, and hill start fails to work again?
I cannot understand why mechanics cannot figure it out. Weird.
Hope they resolve it for you soon.
PS.......Not the first time i have seen 'impossible to fix' problems on cars.....
Interestingly I had a Vauxhall Tigra convertible for years, and no-one including Vauxhall or the Tigra forums could figure out where the resistor bank was, (it gives different voltages 12V, 9V, 6V and 3V) to get 4 speeds on the ventilation fan. Owners hunted high and low, stripping the dash and vent system down to find it. But never did
When my vent fan packed in with a burned out resistor bank, I had to put my own 'made in china off ebay' variable speed controller on the fan to get different speeds LOL. A real 'Heath Robinson' fix.
Mind you you cannot do a 'Heath Robinson' fix on a hill start system, as its a crucial safety feature, assuming it works >
