1998 S70 T5 Bad ground, fuse, relay, corrosion or oxidation?

In anther post I mentioned trying to put back together the alarm system which was already gutted when I purchased the car in 02/2012. Installed an Alarm Module a couple of months back and you can hear the door actuators but it only moves one or two of them every so often which is like not having them work at all.

Now to the problem but a good one and that is the interior lights started to work in conjunction with the doors for the first time out of no where. Several months ago I finally installed a small but bright LED below the center console cup holder so I can see the interior after getting tired of being in the dark for nearly 2 years. Anyways, along with this sudden interior lights working the door actuators are operating more often and stronger now also.

So the question is, is there a ground wire, fuse, relay or bad connection somewhere that needs attention? It seems the interior lighting and alarm module and door actuator are all tied together some where, maybe? Thanks.

Blessings,
