Car steering opposite directions?

So I had a car that worked perfectly fine, and one day they randomly started turning the opposite direction than originally. This is the part of the script that controls that motor turning, any help?

after some more testing, I found that this was the script that controls this, this first script is full and is local, the 2nd script is server and is only part of the original script

wait(1)
SeatValue = script:WaitForChild("Seat")
if SeatValue:IsA("ObjectValue") and SeatValue.Value and SeatValue.Value:IsA("VehicleSeat") then
	seat = SeatValue.Value
	car = seat.Parent
	if seat:FindFirstChild("RocketPropulsion") then
		seat.RocketPropulsion:Fire()
	end
	local RemoteControlled = car:FindFirstChild("ControlByRemote")
	while seat:FindFirstChild("SeatWeld") and RemoteControlled do
		wait()
		if not RemoteControlled:IsA("VehicleSeat") then
			break
		end
		RemoteControlled.Throttle = seat.Throttle
		if car:FindFirstChild("LeftMotor") then
			car.LeftMotor.DesiredAngle = seat.Steer*math.rad(30-RemoteControlled.Velocity.magnitude/4)
		end
		if car:FindFirstChild("RightMotor") then
			car.RightMotor.DesiredAngle = seat.Steer*math.rad(30-RemoteControlled.Velocity.magnitude/4)
		end
		if car:FindFirstChild("Configuration") then
			if seat.Throttle == 1 and car.Configuration:FindFirstChild("Forwards Speed") then
				RemoteControlled.MaxSpeed = car.Configuration["Forwards Speed"].Value
			elseif seat.Throttle == 0 then
				RemoteControlled.MaxSpeed = 0
			elseif seat.Throttle == -1 and car.Configuration:FindFirstChild("Reverse Speed") then
				RemoteControlled.MaxSpeed = car.Configuration["Reverse Speed"].Value
			end
		end
	end
	if seat:FindFirstChild("RocketPropulsion") then
		seat.RocketPropulsion:Abort()
	end
end

SECOND SCRIPT (SERVER)

while true do
	for i = 1, 60 do--60/30 == 2, 2 seconds between deciding if it's upside down
		wait()-- we want the steering and sfx to update as many times a second as we can
		if workspace.FilteringEnabled then
			if car:FindFirstChild("LeftMotor") then
				car.LeftMotor.DesiredAngle = seat.Steer*math.rad(60-RemoteControlled.Velocity.magnitude/4)
			end
			if car:FindFirstChild("RightMotor") then
				car.RightMotor.DesiredAngle = seat.Steer*math.rad(60-RemoteControlled.Velocity.magnitude/4)
			end
		end

Try using this:

 if Base then
    if Left then
        leftMotor = Instance.new("Motor6D", car)
        rightMotor.Name = "LeftMotor"
        rightMotor.Part0 = Left
        rightMotor.Part1 = Base
        rightMotor.C0 = CFrame.new(-WheelSize/2-Left.Size.x/2,0,0)*CFrame.Angles(math.pi/2,0,-math.pi/2)
        rightMotor.C1 = CFrame.new(Base.Size.x/2+Left.Size.x+WheelSize/2,0,0)*CFrame.Angles(math.pi/2,0,math.pi/2)
        rightMotor.MaxVelocity = motorSpeed
    end
    if Right then
         = Instance.new("Motor6D", car)
        leftMotor.Name = "RightMotor"
        leftMotor.Part0 = Right
        leftMotor.Part1 = Base
        leftMotor.C0 = CFrame.new(-WheelSize/2-Right.Size.x/2,0,0)*CFrame.Angles(math.pi/2,0,math.pi/2)
        leftMotor.C1 = CFrame.new(-Base.Size.x/2-Right.Size.x-WheelSize/2,0,0)*CFrame.Angles(math.pi/2,0,math.pi/2)
        leftMotor.MaxVelocity = motorSpeed
    end
end

Hello. Try using elseif Right then.

if Base then
    if Left then
        leftMotor = Instance.new("Motor6D", car)
        leftMotor.Name = "LeftMotor"
        leftMotor.Part0 = Left
        leftMotor.Part1 = Base
        leftMotor.C0 = CFrame.new(-WheelSize/2-Left.Size.x/2,0,0)*CFrame.Angles(math.pi/2,0,-math.pi/2)
        leftMotor.C1 = CFrame.new(Base.Size.x/2+Left.Size.x+WheelSize/2,0,0)*CFrame.Angles(math.pi/2,0,math.pi/2)
        leftMotor.MaxVelocity = motorSpeed
    end
   elseif Right then
        rightMotor = Instance.new("Motor6D", car)
        rightMotor.Name = "RightMotor"
        rightMotor.Part0 = Right
        rightMotor.Part1 = Base
        rightMotor.C0 = CFrame.new(-WheelSize/2-Right.Size.x/2,0,0)*CFrame.Angles(math.pi/2,0,math.pi/2)
        rightMotor.C1 = CFrame.new(-Base.Size.x/2-Right.Size.x-WheelSize/2,0,0)*CFrame.Angles(math.pi/2,0,math.pi/2)
        rightMotor.MaxVelocity = motorSpeed
    end
end

So basically, after a little research, I found out that roblox, FLIPPED, the motor6D and a bunch of things relating to that. So I just flipped the code a little bit. And it works.
