You have a problem with the daytime running lights system. It could be the sensor, relay or body control module. The sensor is on the top of the dash, there is a panel up there that pops of to access it. (be careful because they do break easily). The relay is in the under hood fuse panel. The BCM is under the dash. It could be one of these or just a bad connection at the BCM,relay, or sensor. These are the reason it flashes. When you turn the lights on manually, it bypasses all of this. Fixing this, you need a volt meter and wiring diagrams.

Disconnect the battery for a few minutes and turn the key to the on position back and forth to drain any remaining power in the system. reconnect the battery after the power has been drained and all your warning lights should be reset. If warning lights re-illuminate then you have something wrong.

Take it to a repair shop,trans shop or dealer & ask

Could be a blend door problem under the dash.
