This post has made me the happiest ranger owner in the world! I've been fighting with my damn door chime since the day I bought the truck. I did everything else but hit it with some WD40. I first tried the fuse, but that also disabled the speedometer and wipers. I tried to unplug the pin from the wiring harness, and although the speedo worked, I didn't realize my wipers were disabled until I was caught in the rain. Thank you rwenzing and R-F!!!
