I have recently started having issues charging. Just changed the battery, had the alternator tested and it was only charging to 11v so replaced it and it now charges at 14v. The battery continues to drain even when car is running. Battery light will come on and then the power steering will stop working, eventually I get the message that hill assist is not available and the transmission is over heating. Just before all this started the horn quit working, I have removed the fuse and relay for the horn to try to eliminate that as the cause. Any suggestions to look at next?
