possiably.....It could be your main driver side window switch. My sisters car had that problem but it was a Pontiac.... so that might be it.
Check under the hood for any "fusible links" that may have blown.
Open hood, It is on the passanger side under the hood attched to the bell houseing on the tranny. I thinking to the right of the alternator.
Masterlock is recognized around the world for reliable locks. The locks are tough under fire, pressure, driving cars over them, and determined copper thieves trying to cut locks on cable cars.
The relay switch for the locks on a 99 Chevy Suburban is located under the driver-side dashboard.
Try syncing it again if you checked under 'video'.... but if you haven't and tried to look for it in music, it's most likely in the 'video' file.
Did you check the fuses in the power distribution box under the hood?
If you have a new house, you probably have window locks already. These are a huge benefit to a homeowner, so the newer models of windows all have them. This has not always been the case, however. If you have an old home that you are working to fix up, you might want to consider adding some window locks. This should at least be done for all of the windows on the first floor. This will give your home safety & security even when you are gone. The locks are very simple, generally consisting of one metal part that twists under another.
If you have already checked the fuse, then it must be the relay switch under the front dash or in the fuse panel
There is a factory service bulletin about your problem. The software in the body computer needs flash updated. That is only available at the dealer.

The best thing to do is have it checked out by a doctor.
