@CaptainHero when I was checking for drains I only found a drain from the alarm siren and from REST staying on non stop. 35 might have an effect but there are 5 fuses related to the REST/climate control .When REST wouldn't shut off the blower, aux pump and duo valve stayed on draining the battery.after using the junkyard SLK control module I hooked put all the fuses back and put the springs back in the proper location in the valve. Everything works now, (except the siren I unplugged) no drain. I'll put my charger on the battery overnight and double check the draw tomorrow.
