I have an 03 envoy,I am installing the RS-915 Autopage system with GMDLBP,I am having an issue,sometimes on disarm the doors will unlock,and sometimes they will not,I am getting a signal from the alarm system each time (verified with test light) but they just do not always open. Im also having same issue with locking,sometimes lock sometimes dont. All connections are soldered and I am using the GMDLBP to control the locking/unlocking of course. Can anyone please take the time to look up the wiring information for the alarm system and the GMDLBP and help me troubleshoot this? I would greatly appreciate it,I would even be willing to pay someone to help me figure it out. Thanks alot!!!
