Had a similar issue and when I took the door panel off and checked it out, the spring for the punch button was messed up and sticking. It wasn't electrical for me. It's an easy job to pull it apart. Just make sure when you are taking off the big nut behind the handle and the little keeper pin you dont drop it inside the the door. Small fingers patience would be an advantage unlike my big stubs and short fuse!!!I recently purchased a 99 GTS. The drivers exterior door release sometimes works. The interior handle / release always works? Has anyone had this problem before, and what is likely wrong? Any help would be great.
