Electrical Issue - Psgr Door Elect/Keyless Don't Work

Got a weird one here... Yesterday, on my 2003 Avalanche, I noticed my keyless remote stopped working (figured it was the battery int he remote). However, I then found that none of the elctrical in my passenger side front door work (mirror, heaters, window, locks).

Anyone ever see this before? Any thoughts? Didn't notice any blown fuses under the hood or in the drivers side panel.

Thanks!
