It is a wise decision to disconnect your door lock module: see my writing at http://www.geocities.com/dmcjoe/doorlock.html The problem you are describing may be "ground fault" related. Inspect the battery ground connection at the RR trailing arm bushing and the electrical compartment ground connection located at the top of the RR frame section located just below the coil cover.
