Hello, I recently encountered a problem with my 2004 Acura TL: I turned on the car yesterday, and I instantly noticed an unusual whirring noise; I looked down at my instrument panel, and I saw the battery light was on. I didn't notice any problem in regards to performance, so I just drove it for the rest of the day. It continued this morning, but then all the indicators appeared. Then, the radio and windows stopped working, and the car shut off. I assumed it was the battery, so I replaced it. Everything works perfectly, except for the driver's side auto-down window button - which is odd - and the battery symbol is still on... Has anyone else had a similar experience? I'll appreciate any input.

 

Anyone?

 

The battery warning light can indicate a charging system problem.
Check your alternator and belt

Also, your window needs to be reprogrammed:
1) turn car on
2) roll drivers window down all the way
3) roll window up and keep holding the button in the up position for 2-3 seconds after the window is all the way up

 

Your alternator may be bad..check belts....your new battery will die!..my money is on the alternator
