RepairPal Certified shops can diagnose and repair your 2007 Chrysler Pacifica. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Anything is possible, and something definitely happened as a result of the servicing if the speedometer stopped directly after the work.
Check externally first -- all wiring connected as proper? I'm not sure what you could disturb inside, but certainly it is possible.
