I think I get your "point". I was thinking on the way home in THIS car (it still drives fine) that I really ought to swap out this CLP/SSM unit (which I refer to as "the brain") with the one I got from down south. My 1st repair was splicing in a large replacement connector since the females in it were ruined, while the males were salvageable on the other end. Everything worked fine for a while--perhaps a year or so, and then my h/lamp delay ceased to operate and I lost all my interior lights... I started "dreaming" of disassembling that trunk area again (UGH!). Now I stopped hearing the little motor running when I 1st fire up the car (Pump??) so THAT may be the real issue. Are these little pumps available separately? Chrysler? Mercedes? Also, why is the RED light blinking (signaling "engaged") for the "TOW" button, and why can't I shut it off at the rocker switch? That has me a bit worried too. I'll be feeding back here what I eventually find out. For now, I am away again on Southern Baptist Disaster Relief down near Cape Cod where a tornado touched down a week ago, so it'll be a few days before I can get to looking into this. I am SO thankful for ALL the kind words and GOOD INFO shared here (as usual), and really appreciate this FORUM!!
