I recently bought a 1998 740il

the battery dies when car sets overnight, i had the battery checked and there was a bad cell in it, so replaced the battery, had no problems for like 2 weeks, now its doing the same thing again, battery dies when car sits overnight

also the ac/heat work, but the blower does not come on in the front or the back

there is a shuddering in the front end at 55 miles an hour

it makes a strange whining sound that sounds like its inside the dash constantly

the back tire clicks, when u drive slow it clicks slow, fast clicking gets faster

any enlightment into any of these issues would be greatly appreciated
i'm a salesperson at a dodge dealership, and the dodge mechanics are little help they are convinced i'm more in need of an excorist lol
