Sounds like your VSS (vehicle speed sensor) was either broken or not reconnected properly by the dealer. Go back and tell them that your cruise is not working AFTER their work and that you believe THEY messed up your VSS! Just even hearing that you know what your VSS is should be enough to convince them you're not a sucker and they should do it. If they hem and haw, hold your ground! Bring your father with you to substantiate the problem.

Former, now returned CEG'er! 95SE MTX, (AKA "The Road Rat"). Stock except for:TH fix, B.A.T. big brake kit, tranny cocktail and lots of re-insulated wiring! May yet be a 3.0! "Speed doesn't kill, stupidity does!"
