Battery dying due to seat module. Dealership wants $ 700.00 to correct problem . I disconnected diver side, I will determine whether or not I'll fi this problem.

My battery kept going dead every day. I was told it may be a seat control module. I traced it back to the passenger CSM. After I disconnected it, the battery stopped going dead. The CSM is supposed to shut off when you turn the car off. Apparently the CSM does not shut off completely, thus draining your battery.

Constant inexplicable battery drain. Diagnosed by mechanic. Disconnecting the fuse solved the problem until it was fixed.
My battery kept going dead. It ended up being the seat control module. Im had to diconnect the passenger CSM. it was okay after that. You would think that it would be a recall...
