My right rear door ajar switch was replaced and it was okay for a while, but now it is giving me trouble again. Could this be coming from bcm? Left speaker no sound. Sometimes mirrors move in on there own.

The speaker issue would be either a connection or radio problem. For the door ajar there is a connector on the kick panel, for the mirror and maybe door. See if that is loose and put dilectric compound on connection. Same with bcm connection and finally have it scanned for codes as it may be the bcm a professional will have to do that.
