2000 xj8 119010 miles ,this is my wife's car she only drives about 50 miles a week around town. so problem with power steering it is stuck in highway mode tight steering when normal driving around town. so far I have changed power steering high pressure line due to small leak , then power steering pump ,then power steering rack, new tie rod ends so I am stuck as what to do next so any advice on what to do next would be greatly appreciated thank you in advance jrb53

 

If car has speed sensitive steering then there is module for it. I'd start from the basics being grounds, powers and fuses. If there is no electric connector on on the steering rack I'd suspect all rusty lower steering shaft U joint. It could be it with adaptive steering too. Mine is rusty and steering becomes angular and stiff unless I grease it in regular basis.

 

where are the fuses and module located in the book I have it dose not list them thanks

 

I have attached extracts from the Electrical Guide showing:

1. Module location
2. Module diagram
3. Link to Instrument Cluster
4. Link to Fuse Box
5. LH Heelboard Fuse Box

 

so I checked all fuses and grounds all good so got a new servotronic module .still the same decided to take it to jag specialist Dana at Upton motors in Upton mass who is a forum member in about 5 minuets said I had a broken wire from the plug to the harness so its going in next week to be fixed . will post again to let you know how it goes thanks to the forum again for pointing me in the right direction jrb53
