Dashboard light issue
When I turn the car on my brake light
comes on and it will turn off if I hit
the circular air button next to the AC.
What do I need to do to fix it.
sounds like you got a short in the system or a bad control module. I would recommend heading to a vehicle electrician and having your cars electrical checked out.
