I could not get my speedometer working. Took it to a shop and they said it was blowing a fuse related to airbag module? They unhooked the airbag module and speedometer and odometer are working now, but I have no airbag. He was checking on the module price. Is anyone familiar with this part or issue? Only 2nd time I have had to take it into a shop.
