2003 Bonnaville Problems

The power windows & locks just quit working on the passenger side and both back doors. Can any one help' thank you. Checked fuses they are all fine! Tried new switches on drivers door. didn't help.

Do you have a light on that says " Service Vehicle Soon " ? Its possible you may be having a Body control Module issue

I've been researching this for about a week. To the best of my knowledge it is the data link brown and white wire under the carpet drivers side = bad connection.
