Hey everyone I need some serious help. My battery keeps dying in my x5 when i let it sit over night. It is fine when i drive it during the day but when i am let it sit for more then a few h ours it dies. What should i do. I replaced the battery and it did it again. Also now my door locks wond work or my overhead lights. Do i have a short?

HVAC resistor pack did this to my familys 3.0.

Part was $80. I installed it in less than 30 minutes. Just pops right in.
