Just came back from being overseas for a year and took my '02 M5 out of storage. Reconnected the battery and noticed the interior blower won't shut off. None of the climate controls work. It's stuck on high heat which is not pleasant but it least it's winter. Also there are no lights working on the climate control part of the dash. I did the research here and pulled the FSU and replaced it with another one from my daily driver/beater '97 540i. FSU had the same part number on it and looked identical. Nothing changed, still no lights and heater blower stuck on high. Any ideas before I take it to my Indy? I'll be driving around with the FSU disconnected and then just plug it in for high heat when needed.
