corvette VMU ?
Been having trouble with the door locks lately, I know this is a fairly common problem. Called the dealership and they said I might need a new VMU (?), which controls everything electrical in the car. I think he said VMU, couldnt really hear him too well. Anyone have any guess as to how much this will cost, or if it's even necessary. Thanks for any help.

Sure can...
passenger door won't unlock using key fob or door switch.
driver door won't lock with key fob, occasionally will with door switch.
that's the only problem mechanically the car has so i'm not sure about replacing the BCM

When I bought my Corvette, the drivers door would not lock or unlock with the FOB or the switch. I replaced the door control module and all has been well since. There are plenty of posts on the subject, but I don't remember the BCM being the answer to any of the door lock problems.

Sounds like the very common problem with the relays on the door control modules that control the door locks. I just bought my Z06 about 10 days ago and the driver's side door would not lock or unlock with the fob or with the door switch. I ordered new relays from DigiKey.com for a couple bucks each, removed the old(bad) relays and soldered in the new ones. Took me about an hour and a half of being lazy and taking my time. Worked like a charm. The power lock now works flawlessly. Not bad for $10 in parts. I even ordered extra relays for if this happenens again in the future.

You also need a Framit Flux Capacitor. I have one I can sell you for 50 bucks! 
The dealer will try to sell you the most expensive part for the most expensive price that they can charge you.
I have seen cases where just un-plugging the module and reconnecting it fixed the problem. Do you think the dealer would say. "Oh the good news sir, it didnt need a new module. We just found a bad connection!!!!
NOooooooooooooo! You getting a new module if you needed it or not!
$1200. dollars later, your on the road.
If you need C5 electronics, contact Gene Culley at GM Parts Warehouse. He will beet that price by 1/2 if not better!
Read your DTC's and post the results. If we can see what DTC/s your throwing, we can help you!

Go to “technical data base” and then to “Corvette ECM Computer Codes”. Then select your year car. Read the instructions and then scroll down to the "READ MORE" window to view the code definitions.\
Here is another very good site:
