Hi, When my headlights are and I turn my right turn signal on, the entire instrument cluster blinks along with the turn signal, and when I turn my lights on the right blinker stays solid and the back right taillight goes dark. Does this mean that my back right taillight bulb needs to be replaced. I have replaced the fuses and everything.

Check the bulb first. If it is good, it sounds like you have a ground problem. Check for rusted, broken. Body grounds.

What happens is the power is trying to find a ground, so it uses the one in the inst panel causing it to flash.

Let me know what you find.

I resolved the brake light issue, but not I have a parking light issue. The front left blinker works, but the parking light doesn't. I changed the bulb twice and switched the bulbs and still the same result.

Have you checked the socket with a test light? Many times the socket goes bad.

Let me know.

I tried to resolve the parking light not working, and decided to put a fresh bulb in. I did this turned the battery on to ensure that the blinker was working. Then I tried to start the car and the car wouldn't start. The battery was fully juiced because there was power in the cabin. I jumped the solenoid and it tried to turn over so the problem seems to be electrical, but it was very all of a sudden. Earlier in the day I started the car quite a few times while recharging the air conditioner. WHATS WRONNGG. Thanks for all your help!
