Disconnect battery for about 5-10 minutes then see if your code has cleared. If you have access to a code reader that would be your best bet.

My personal suggestion would be to go for t hese repair catalogs from www.reliable-store.com instead. much better language, complete manual of 800+ pages, and they also have live assistance feature

Hi
I know on my commodore it has a code that I can enter I need to access this by using the buttons on the dash that are used for checking fuel level till empty, distance to go, distance travelled etc.
Could be the same for you worth a try problem is you need the code for your car.
Most are factory set at 0000 but you only get a couple of goes.
Regards Craig

Could be in the ignition switch. I'd try jiggling the key around and see if things change

doubt it very much
the only gears in action are the axle spider ( spur gears ) and they turn very slowly on turns
pinion and crown wheel, noise are growls and whines depending if accelerating or costing and makes no difference if turning or straight ahead That should save you $ $1500.00 for a diff center that costs only $450.00
indicates wheel bearings or brake pads ( linings ) worn out and the callipers rubbing on the rotor ( drum)
I would be checking at the wheels and wheel bearings for the problem

Check head gasket. Pull spark plugs and perform compression check? Check plugs for fouling. Check engine oil for water/antifreeze
Hope this helps?

first swap to a front tyre to eliminate that issue


new bearing shouldn't be rumbling
to get the bearing square on and home
did you use a press to fit the bearing to the rear axle
or tube method ?

and did the seal kit have this nifty plastic seal fitter so axle didn;t rip the seal surface

Check for an air leak in the fuel line.

Wiper motors on this car are a very rare failure, so have you jumped 12 volts to the wiper motor and does it work or not, do that before you tear into it. The switch is the more common issue. Also the wiper motor can be tested with a Ford special scan tool called and "NGS", it runs the wiper motor through it's cycles by controlling the BCM..
