My second electrical question, and I promise that I will now buy a Haynes Guide.
I am responsible for the routine maintenance of a 2004 Ford Mondeo 2.0 Estate originally owned by an Ambulance authority as a fast response vehicle and now owned by the Community First Responder Scheme of which I am a member.
A few days ago, the rear wiper packed up in mid-sweep and I've just had a look to try and troubleshoot the problem. I don't currently have the car with me (I put it back together so that the duty Responder could take it away), so what I now write is from memory.
Many thanks.

- Three wires lead to the rear wiper motor.
- If I remove the connector and then test the free end for voltage I find that I have 11.87v across the outer two pins and nothing from the middle pin to either outer.
- Moving to the motor, I find that I have 1k resistance across the outer two pins and open circuit from the middle pin to either outer.
- The arm is currently stopped almost exactly mid-sweep.
Many thanks.
