Thank you for contacting Jetta! 

We are happy to help. We kindly request that you confirm the below: 

• Has this been an issue since installation, or has it just started?
• When engaging your air button, do you hear clicking coming from your pump? 
• Check the red hose connection at the pump and the air button. Ensure there are no kinks in the red hose or anything restricting airflow through the hose.

If the troubleshooting steps were unsuccessful, please reach out to sales@jettacorp.com for additional support.   

Thank you for choosing Jetta!
