2021 Toyota Corolla, all lights flickering after battery recharge

Asked by Clubmanager Aug 09, 2021 at 10:07 AM about the 2021 Toyota Corolla L FWD

Question type: Maintenance & Repair

My son didn’t drive it for weeks and battery died. It has an aftermarket remote
start on it and I’m sure that drained it. When I recharged battery and
reinstalled, the car starts but all lights flicker in a steady pattern...except the
headlights. Interior lights (except overhead) do the same. I’ve no clue how to
stop it and advice online ineffective but that was for other vehicles.

I would remove the aftermarket system. It is possible the voltage regulator was damaged.
