I spilled some syrup into the left speaker vents (MacBook Pro Early 2015)

Tale the computer to an authorized service center for evaluation.

Put your homeowners/renters insurance carrier on notice of a loss as soon as possible. Unless you have AppleCare Plus, repair of liquid spills are not covered by Apple.

Too often, MacBook Pros with spill damage are beyond practical repair; many residential policies cover accidental damage to your tech. There will be a deductible of course, but the policy may reduce the financial pain if a new logic board is required or the computer is declared a total loss.
