Left Blinker wont go off at NIGHT

[BasedGP]

Well, during the day my blinker is fine, but during the night, it will stay on. The right blinker is fine, and this only happens at night. Also, when I turn on my right blinker, the mileage lights blink!

This has the headlight controls on the turn signal lever, yes? If so, the problem is probably in that multi-function switch.

So, what are some manuals to take this off for a 1999 chevy malibu!
