I had a similar problem with my 2005 Vectra...door lock worked from the remote but not the storage doors and also not from the rocker switch from inside the main door. I contacted the manuafacture who walked me thru a diagnosis and said the main control had a bad circuit and needed to be replaced. I also noticed that a couple of my compartment locks were froze in the locked position and even the key would not release them. Long story short when I took it to the dealer they replaced the Main controller, all the compartment switches and the remotes...
