Brake,engine and oil lights coming on and off when this happens have no signal lights inside but they work outside car runs great all fluids checked and are good what is the problem sometimes lights stay on a while then go off for a while the does it again
wandaevans50 that is all pretty generic and could be a single sensor. For a start, have the OBD scanned and see if it gives you an error. It appears as if this originates from the BCM due to the no signal light issue, but without a scan it’s just a bunch of guesses.
Check the fuses and battery. If any fuses are blown just replace them. Same as battery. If the problem persists you gotta just suck it up and go to a repair shop. But try your best to repair it yourself. You will save so much money.
