1992 Lexus SC 400 V8 Two Wheel Drive Automatic 127000 miles
While driving at 65 MPH on an interstate with the cruise control on, both the speedometer and the cruise control failed simultaneously. We installed a new sender (located ion the tail of the transmission) and installed a rebuilt gauge cluster. No luck with either/both. Could not get an electronic wave generator (which facilitates a car's motion) to move the speedometer's needle but, shorting the line briefly did get the needle to jump slightly.
So, what would you look for and where would you start the diagnostic process?
Have a good day.
have the same problem?
