Hello all , nice site . I have been reading up and this seems to be a common problem . But , what I find is that after replacing the DRAC is suggested there are no follow up posts telling us if it corrected the problem . In any case , it didn't with me . I have replaced the VSS , DRAC, and gauge cluster. My truck is a 92 C3500 5speed 454 2wd . Only other problem is the brake light stays dimly light ( and I read that's common with speedo problems ) any advise would be great . Thank you in advance
