1997 Legacy Gt 2.5 Power door locks

[Joenasnj]

I have a factory keyless entry system. The problem is i can lock all doors and unlock the drivers door. It will not open all the other doors. The manual says to hold down unlock button to open all doors. I have tried this and it doesn't work. Is it the remote itself or the door lock module?

 

thanks Joe

You have to hold the unlock button for about 3 seconds for all the doors to unlock. For my 97 I noticed this feature starting to fail. The driver door would unlock but the rest... maybe if I was patient. The solution for this was a new battery for the remote. I figure that the battery was so low it could not maintain a signal for the 3 seconds. I measured about 5 volts on the battery at that time. It is a 12 volt battery new. (type 23A)
