I got a 2000 Hyundai Accent and I went to go to the car wash and then the parking lights were flickering and acting crazy. I pulled the 30 amp Lamp and ignition fuses and the 20 amp ECU. Left it over night and replaced the fuses I pulled out since they're good fuses. Everything worked well after that. I also replaced the A/CON relay with the tail lights and activated the AC and it ran so the relay isn't the issue. Any thoughts on what can cause this?
