Stiff steering /
Hello
the steering has got fairly heavy on my LHD '97 xk8 convertible.
There is assistance but not much.
I guess some problem with the servotronic / variable assistance.
Any tips on diagonosing?
I have read removing the glovebox and getting to the servotronic module and measuring resistance between the solenoid pins that should read ~ 7.5 OHM .
Any other tips?
thanks lots!

Fuse # 12 / 10 amp red driver side fuse box
Door mirror heater control relay
Right cabin blower control relay
Left cabin blower control relay
power to the Air Conditioning Control Module
You can unplug these relays and modules and see if one is sucking the power down out of the steering servo other then a blown fuse .
Didn't pick the weather .

Thanks guys for replied.
Its got got to be an electrical problem as it manifested from one day to another just like that. Racks pumps etc would gradually degrade won't they?
one day the whole assist was off so I could barely move the steering wheel when parked. It went back to normal next day and now it seems to have settled in this half assist mode.

Thanks! I pulled out fuse12, A/C is off but steering seems unaffected. I only see one relay there. Where are the other 2?Also what's the easiest way to get to the servo to tap it?Thanks!

Simple question.
Does the A/C blower work? Put the aircon on and check the blower works.
In other words switch it on then turn the same dial.
When I got my car back from recent repairs it turned out the be the plug on the steering column had not been put back in. The steering was very stiff until it plugged in again. Its accessible under the car near the CAT.
If you look up to the right of that rather rusty looking steering coupling you can just make out the un plugged switch. It has a bit of white plastic showing.

Yes a/c works perfectly. Will check the rack connector plug. Thanks for the tip!

On the X300 there are 2 as the trunk dome lights you can use . I would recommend soldiering a 3 foot length of wire as this would eliminate the possibility of a original wire in that area already compromised in the tight space and exposed center conductor and shorting . The release bar works by depressing toward the center , the same toward center on installation . Clean the servo socket pins with a acid brush and some bulb grease before you put together

Hey guys. After festivities finally had a chance to follow some of your recommendations. Checked continuity , voltage , resistance, and couldn't find any problems so sourced a replacement servotronic module and voila. Problem resolved !!!
thanks lots.
Will open pen the old one see if I can see a burnt component and maybe I can fix and pass on to
so
ebody that may need.

Just a mild note... My power steering went a little wacky when I change the battery last time. I did use a power pack on the cables when replacing battery to prevent memory or electrical problems. My steering was very stiff, center line only. Had a hard time steering straight line. Driving a bit with a few start cycles and it did clear up. Rich
