A few days ago I was washing my car (2008 FX35) and I noticed a strange clicking kind of noise coming from my car about every 45 seconds or so. I thought it sounded kind of like the power door locks. The noise finally stopped. A day later I noticed the door lock switch on both front doors will lock the doors, but will "NOT" un-lock them. Also I noticed several months ago the switch on the driver door was a little sticky, like when I pressed the switch in either direction it would hang there and I had to press it in the opposite direction to get it un-stuck. I'm thinking maybe I accidentally hit the door lock switch, it got stuck and I didn't realize and it caused damage somewhere. If it were a bad fuse I would think the switch wouldn't work at all. Anyone got any knowledge or bright ideas about this ? Thanks.
