Hey guys i have recently had the same problem in my r32. Thought i would search first and found this thread.
My speedo stopped working first, then 30mins later steering went heavy. Power fc isnt getting reading either. Guess thats cos it reads it from the speedo cable which leads me to think that the cables the problem. Also i have an rb25det gearbox. Do the r33's have a sensor in the gearbox that converts in to electrical signal or is it a cable to the dash like r32 because my rb25 gearbox has a cable coming from it to the dash.
Also i spun the gear in the back of the dash with my fingers and the power fc picked up 20km/h but the stock speedo guage didnt so would this mean that the cable is snapped somewhere or that there is a problem with the gearing inside my dash cluster??
Power steering is now intermittant too. 1 min its working fine then the next, it goes heavy.
Hope that all makes sense. Any help would be greatly appreciated.
Cheers
