My left turn signal will not work even tho I have replaced both front and rear bulbs. the flasher works rapidly but no light blinks. the right works fine, any suggestions? ---

Yeah, if this really is a 2020 the warranty should cover it. ---

Sounds like a short to ground on the left side, does this vehicle have add-on trailer hitch wiring? ---

Yes the dealer needs to deal with this under warranty. ---

If your vehicle is **really** a 2020 model, then EVERY problem should be covered at this point by the **multiple** warranties, and your dealership is responsible for any and all repairs. Then again, since the LeSabre hasn’t been manufactured since 2005, I have a very hard time believing that the OP owns a 2020 LeSabre. Could the OP **please** clarify the make, model, and model year of his/her vehicle? 🤔 ---

Take a close look at the front and rear bulb connectors , GM had had some issues with these melting .
