why do all dashboard lights flash on and off causing wipers and seats to activat

Hello, all dashboard lights flashing on and off, that's quite a concern to experience. Have you tested the battery state of charge? Also, the ability for the battery to fold and sustain a load on it? My thought is that you may have low voltage a lot of the time causing intermittent electrical issues. Additionally you could have soomoe kind of concern with water getting into control modules due to water leaks in rain storms and so forth. Has the windshield ever been replaced, for example? Maybe it was not properly sealed? All guesses, and hands on testing is really what would be helpful. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
