Disconnected negative terminal and all hell broke loose
This involves a 2006 bmw 525xi with 154,00 miles and an unknown history aside from that it has had repair secondary to front end damage. I have had the car for 6months.
I did as the title states before checking the climate control fuses. I thought i should do that after a scan at autozone showed it was likely a thermostat issue as the cause of no heat. I figured it wise to rule out fuses first before the hassle of replacing the thermostat. I never suspected all the warnings that this would come from such a simple check of the fuses.
The fuses checked out ok. First thing after re-fastening the negative terminal was the windshield wipers would not turn off. So, i took that fuse out. Then i noticed the warnings of "AWD DSC 4X4" and then found my high beams, turn signals, and speakers did not work. I also have a brake notification lighting up on the dash.
There is one thing that happened that i am suspect of causing all of this. When i re-fastened the negative terminal, i was in a hurry as i was on lunch break and instead of using an extension with my small ratchet, i used only the socket and ratchet. That left for little room between the metal bracket next to the battery and the ratchet lever. I ended up bumping iit. Since it was the negative terminal i was working on, that should not have caused all i mentioned, or could it?
Otherwise, what could have happened? I am driving it as little as possible as it is my only mode of transport. I do not have a trusted indy or bmw dealer nearby. I do have the Bentlet manuals but could use all the help i can get in solving this. If i could do it all over i would never have unhooked fhe negatively terminal, at least not until it was absolutely necessary because no heat is better than all this added on. Any guidance is greatly appreciated.
