UPDATE: Problem resolved! Short version.... Issues was a bad HVAC AC/Heater Control module. Replaced it with one from a 2002 SLK230 from the salvage yard. Why not the OEM part? Well, it was cheap and I was curious to see if it would fit/work! Read the below thread for more info. Thanks to the folks who replied!

Hello all.

Long time Crossfire fan, first time owner. I searched all over but have not found an answer to my problem anywhere.

I'm working out the electrical bugs as I have some battery drains. 1 was the alarm siren, I unplugged it. 2 is the REST function staying on with the key out until the battery is completely dead.
The aux pump and blower motor (low) stays on and the heater control valves are hot without running the car at all. The REST button does not turn it on/off, the REST light on the button does not come on.
I live in Florida so I really don't need the REST function and would just disable it if I knew how.

Fuse #15 seems to stop the pump and the heater control valve but how do I stop the blower from continuously running? I ordered a new resistor but I'm not sure that is going to fix it.
Looking into Mercedes with the same feature I found this relay "N11/6 Automatic heater control time-limit relay" . Does anyone know if/where this might be in the Crossfire or how the REST function knows when to shut off? thanks
