Hyundai Elantra Coupe 2.0L Engine Discussion
2023 Elantra base. I put LEDs in almost a year ago and no issues. Recently only 1 headlight works at a time and one is extremely dim. They both work high and low just not at the same time.
Checked OBD and zero codes. Looked in the manual for the relay and there doesn't seem to be one.
Need some...
