I have been getting two inconsistent messages lately from my display:

Defective display: shows what looks like a windshield wiper icon and sometimes a battery looking icon. the message comes on about once in two days, then clears out.

BAS: I have had the brakes checked twice, yet i still get this message at least 2X/week.

Question: Should I just take her in? Is there something to check? Where can I have codes read, without checking her into the hospital.

Thanks for any suggestions. I did a search and didn't find anything.
