So, I have a 96 sl500 with the Infrared locks that go through the mirror only. My current problem is as follows>

The locks will not unlock with the fob. I can lock them though, just not unlock. I can lock and unlock with the key in the door or with the switch on the dash. When I try to unlock the pump in the trunk runs a few seconds and the mirror flashes.

Anyone have any ideas, suggestions or solutions?
