Forgive me if this exact problem is discussed elsewhere.
Both FOB keys now won’t lock or unlock the doors. The car lights flash like they used to but there's no noise or results. When I start to drive, the doors and rear hatch lock themselves as they should and when I stop and open either door, they all unlock. I removed the passenger side trunk panels and all looks clean and new where the little hoses travel and no apparent water damage. I'm about to buy a used (with warranty) vacuum pump and do a swap. Should I just go for it, or is there another potential problem? Coincidentally, this problem started when I had the rear shocks repaired.
Thanks!
John
