I have a circuit I have modeled on TinkerCad using two DC motors and an L293D motor driver, when I change the max speed of my motors in my code, motor2 changes its RPMs accordingly but motor1 either does not change or is just 0 RPMs depending on the value. Why is this happening?(I can't upload the schematics because I'm a new user 
Here is my code:
#include <Servo.h>
// Motor control pins for L293D
const int Motor1Enable = 7; // Enable pin for Motor 1
const int Motor1Pin1 = 9; // Input 1 for Motor 1
const int Motor1Pin2 = 8; // Input 2 for Motor 1
const int Motor2Enable = 5; // Enable pin for Motor 2
const int Motor2Pin1 = 3; // Input 1 for Motor 2
const int Motor2Pin2 = 4; // Input 2 for Motor 2
const int SlideSwitch = 6; // Pin for the slide switch
const int ServoPin = 11; // Pin for Servo
const int MaxMotorSpeed = 25; // PWM value to limit speed to ~2200 RPM
unsigned long motorsStartTime = 0;
unsigned long servoMoveTime = 0;
bool sequenceRunning = false;
bool lastSwitchState = HIGH; // Assume switch starts in OFF position
Servo myServo; // Create a servo object
void setup() {
Serial.begin(9600);
pinMode(SlideSwitch, INPUT_PULLUP); // Slide switch as input with internal pull-up resistor
// Motor pin setup
pinMode(Motor1Enable, OUTPUT);
pinMode(Motor1Pin1, OUTPUT);
pinMode(Motor1Pin2, OUTPUT);
pinMode(Motor2Enable, OUTPUT);
pinMode(Motor2Pin1, OUTPUT);
pinMode(Motor2Pin2, OUTPUT);
myServo.attach(ServoPin); // Attach the servo to its pin
// Initialize motors to OFF and servo to 0 degrees
stopMotors();
myServo.write(0);
}
void loop() {
int switchState = digitalRead(SlideSwitch); // Read the state of the slide switch
// Detect when switch is turned ON (LOW) and sequence is not already running
if (switchState == LOW && lastSwitchState == HIGH && !sequenceRunning) {
sequenceRunning = true;
runMotorSequence();
}
lastSwitchState = switchState; // Update last switch state
}
void runMotorSequence() {
// Start Motor1 and Motor2 at limited speed
Serial.println("Motor1 and Motor2 starting at limited speed");
startMotors();
motorsStartTime = millis();
// Run Motor1 and Motor2 for 5 seconds
while (millis() - motorsStartTime < 5000) {
// Wait
}
// Move Servo to 90 degrees
Serial.println("Servo moving to 90 degrees (Motor1 and Motor2 stay on)");
myServo.write(90);
servoMoveTime = millis();
// Wait for 3 seconds
while (millis() - servoMoveTime < 3000) {
// Wait
}
// Move Servo back to 0 degrees
Serial.println("Servo moving back to 0 degrees (Motor1 and Motor2 stay on)");
myServo.write(0);
// Run Motor1 and Motor2 for 3 more seconds
motorsStartTime = millis();
while (millis() - motorsStartTime < 3000) {
// Wait
}
// Turn off Motor1 and Motor2
Serial.println("Motor1 and Motor2 stopped");
stopMotors();
Serial.println("Sequence complete. Both motors are off and Servo is at 0 degrees.");
sequenceRunning = false;
}
void startMotors() {
// Set direction and enable Motor 1
digitalWrite(Motor1Pin1, HIGH);
digitalWrite(Motor1Pin2, LOW);
analogWrite(Motor1Enable, MaxMotorSpeed);
// Set direction and enable Motor 2
digitalWrite(Motor2Pin1, HIGH);
digitalWrite(Motor2Pin2, LOW);
analogWrite(Motor2Enable, MaxMotorSpeed);
}
void stopMotors() {
// Stop Motor 1
digitalWrite(Motor1Pin1, LOW);
digitalWrite(Motor1Pin2, LOW);
analogWrite(Motor1Enable, 0);
// Stop Motor 2
digitalWrite(Motor2Pin1, LOW);
digitalWrite(Motor2Pin2, LOW);
analogWrite(Motor2Enable, 0);
