Chad,
The speedometer is driven directly by the speedo cable regardless of
whether the car has
cruise control, or not. The speedo cable drives the speed sensor
mechanically, along with the
speedometer itself. The speed sensor converts the mechanical
rotation of the speedo cable to
a voltage, which is sent to the cruise control control unit. If both
the speedometer and cruise
control don't work, it's probable that the speedo cable isn't seated
properly in it's receptacle
at the back of the speedometer, the cable itself is broken, or the
drive gear at the trans axle
end of the cable is stripped or it's retaining clip has fallen out.
My guess is the cable isn't
seated at the speedo end. Of course there's the possibility of a
huge coincidence - both
the speedometer and the speed sensor have gone bad simultaneously -
not bloody likely.

I believe I damaged the speedometer when going through the
troubleshooting steps for the cruise control. I was going to take the
car on a 6 hour trip tomorrow, but now I have no speedometer or cruise
control. Everything for the cruise control checked out ok except for
the resistance of the speed sensor. I must have screwed it up with
the resistance check when I left the ignition on... ooops. The cable
must not drive the speedometer directly on these cars. Is that right?
Does anyone have a spare speed sensor for a 90 gli 16v? I need one
asap.
Thanks.
