Recall on door window and lock control panel. Should be free at any Chevy dealer. If radio lights come on and all controls work on it. Replace the door speakers. Just two at a time if your not sure. But, I had same issue with my 07 TB. I checked and checked everything. I just did my research on the ole innerweb, Trailvoy is also a very nice web site to get answers about anything with TB's. Hope this helps.
