2007 Dodge Caliber Q&A

2007 Dodge Caliber Question: brake relay

my left brake doesn't come on however the bulb works and the check engine light is on because of it. I'm curious as to how much this would cost to fix. or better yet how to actually fix it. thanks -
Answer 1
A Check Engine Light shouldn't come on for this problem. Can you post the diagnostic code that caused the light to come on? And can you clarify something, what is it that isn't working? The brake light? -
