The shop I took my dodge ram to says they repaired a broken vacuum line and now my 4 wheel drive will not work. I disconnected what they did but it only worked once and will not engage again. Help, deep snow and ice need it right now. I think it is a vacuum problem but not sure. the line fixed goes into a steel tube that has some sort of filter in it.
