Detail: My right rear blinker light on my 2009 Buick Enclave comes on with my lights but does not blink. Additional in the car when I put on my right blinker the internal dashboard signal blinks twice normal speed and then goes into a really fast blinking speed.
Solution: Sounds like you got a bad bulb. turn the blinker on an step out to look at them. there should be a blown one. , Same problem on a 2009 enclave. Running light worked but turn signal did not (rapid blink indicator). Changed the bulb and presto fixo (cheap too). , I suspect a blown fuse on ur Buick Enclave , Hi, a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.
