   Tiny bugs/spiders can crawl into outside electrical things and short the   
   contacts. Might want to inspect the rear door button and see if any   
   "critters" have invaded.   
      
   Also water can sometimes get in there and short things out.   
      
   I place fine mesh screen over electrical vent openings to keep the bugs out.   
   If heat is not a problem as it would not be with a battery operated doorbell   
   button, you may be able to seal any openings with a dab of caulk or caulk   
   around the back edges. (Get any bugs out first!)   
      
   If water is getting in there, maybe build a little covering over it?   
      
   BTW this is where the term "computer bug" came from. A bug was crawling   
   around on the wiring of one of the first computers and caused quite a bit of   
   trouble!
