I have a problem with my front wipers not wanting to turn off at times, even with the ignition turned off.

I've had numerous garages look at the problem and nothing shows up, I've had the GEM module tested, the wiper switch tested, all the accessible earth points checked. A relay has been changed on the GEM and still it happens

I have never heard of another ST having this problem, but I have seen several posts of non Focus ST's having the problem. The GEM module is going to be common to both so I don't see it being linked to a specific model.

Using the GEM self diagnostic I have tested all the input signals and everything appears ok. To date I have not tested the output signals as I've had problems getting that part of the diagnostic to work.

Any help or suggestions would be welcome.
