92 Sc400 Tilt Wheel Issue

I have two issues: I bought my 92 SC400 a year ago. It has the small issues... the speedo doesn't work and some lights in the instrument

cluster don't work. OK so I replaced one of the speedo sensors on the tranny and tested the other one and the speedo

still doesn't work. I took out the instrument cluster and replaced the bad bulbs and tested the speedo electronics with an ohmmeter

and all seem to be ok, ie, no opens or shorts. The fuses are good, of course... So its gotta be the wiring... which is gonna take some time... can anyone offer further advice before I kill myself checking all the wires?

The second issue is the tilt-wheel steering. The tilt work going up and in-out but not going down. So I took off the steering wheel and expose

the tilt gearing. I took the springs off and dropped the tilt assembly away from the steering column and ran it with the tilt switches. It

works great in every direction. I lubed the gear shaft and the cams where they move the steering column, then reinstalled it and tested

it before reinstalling the steering wheel and other stuff. Well, it goes up and down but not before banging into the end. I looked at

the sensors and as far as I can tell they are still good. Any ideas on what else it could be?

THANKS A MILLION FOR ANYTHING YOU CAN CONTRIBUTE...

good
