Regaining Access to Your Service Account
⚠️ Forgot Password
Cause: You cannot recall your password for your ACDelco TDS account.
Solution: We know being locked out is stressful! To regain access, go to the ACDelco TDS login page and click the "Forgot Password" link. You will need to provide your registered username and email address. A verification code will be sent to your email, allowing you to set a new, secure password. Remember to check your spam folder if you don't see the email right away.

Cause: You do not remember your username for the ACDelco TDS portal.
Solution: The password reset process often requires your username. If you've forgotten both, you might need to contact customer support. They can assist in recovering your login name after verifying your identity. Keep any registration emails handy as they often contain your username.
⚠️ Account Locked or Invalid Credentials
Cause: Multiple failed login attempts or incorrect username/password combination.
