Just checked in the book again the locking unit as small plug, so this means that the earth that you need to check is around the rear lights. that's not as bad should be no panels to move, just carpets by the lights.
The main earth point you are looking for is in the tailgate, by the locking unit, you do need to take off some panels to get to it. if that does not fix it, disconnect the second light unit that you have fitted to see if it makes any difference. and did you use a stand alone earth for the second light unit..
you need to get the right one, one with small badge(ford), or one with big badge(ford) they are not swappable, you can't put big on small, different plugs and the steering wheel is different, it looks the same but its not.
had to have my sons car done, parts around £24 and fitting was about £80, did not have to take arms off, would have done it my self if a had the special puller, cost to much to buy puller that you need to do the job..
Hi Pete, Have you checked the tyre pressures. also I am not to sure if the mondeo uses the drive belt or an electric motor to work the steering pump, if it is the belt driving the pump it could be sliping at low revs giving you reduced power to the rack until you speed up.. if its electric it could need changing
is the turbo that you got complete with the wastegate manifold ? if it is, fine, if not the wastegate manifold still needs to come off, do not try and fit the turbo to the wastegate your self, it needs to be aligned with the wastegate or you could damage your engine.
plus have you got the right one for your car, there are two types of turbo, for the focus one as a bottom oil feed / return, the other one as a top oil feed and bottom oil return, yours should have the bottom oil feed / return
disconect fan pulg should be on the battery side of the fan, and connect it to the battery use two wires with a fuse inline., if it comes on the fan is ok,or you can just turn on the aircon if you have it, that will make the fan come on.
Take off door trim, remove the inside cover (where the ajuster for the mirror is) behind that should be about three screws holding the mirror on, take off mirror, and the fitting is the reverse, you can reuse the coloured mirror cover so that it matches
I agree with stef123 use a meter, with the car running the meter should read around 14 volts (13.5 to 14.4) if it is than this you will need a new alternator, also when you changed the battery, was it the right type
