My wife and I just bought a 2018 Chevy Equinox LT 1.5 FWD. Unfortunately we discovered that the drivers side front and rear doors will not lock/unlock with the key fob or by pressing the lock/unlock button on either front doors. You can lock/unlock the passenger side doors from all buttons on both sides and key fob. The lock indicator light does not light up on the driver’s side. It does light up on the passenger side. I read in another forum that it could be a corroded wiring harness. Has anyone ever had this problem? If so, which harness would need to be replaced? TIA
