Hello Tony

How are you doing? Hope you are well. As a first course of action, I strongly suggest that you remove the negative battery connector of the vehicle and let it sit for 10 minutes or more before reconnecting it. I'll be standing by for your response. Let's hope that the reset works. Goodluck

Relly

May I ask the exact year model Tony?

Thank you for that information Tony

The battery of the car is in the trunk and you will need to remove the right side trimming to access it. Below is a video on how to access it. Please click the blue BATTERY LOCATION link below for the video.

If the reset doesn't do the trick, I strongly suggest that you take it to a dealership or have it checked physically by an auto electrician. Although I am suspecting a faulty BCM (body control module). The BCM controls the electrical functions in the car and if it's faulty this issue occur. Below is what it looks like

Yes Tony... disconnecting the battery will perform a reset. You can always go to your email and look for s**t@experthelp.com. That's where my responses will be. I'll be messaging you til you get back. Goodluck!

No Tony... I believe that's a check module not the body control module. Below is what the bcm looks like

Let's just hope that the reset does it trick to cut you the cost. It will cost $100 on ebay but can be cheaper in the yard. Is there anything else I can add or help you with Tony?

That's great and you're most welcome. Good eve Tony!
