Okay need help big time, it started doing it last week, when I go and trim on my car and let it warm up, I hear this thumping noise coming from the bottom of where the glove compartment is, and it sounds like there's not enough vacum if it's trying to open something then cua of the lack of vacum it closes so it sounds again ( thump, thump, thump) any ideas or suggestions on what it is and how can I fix it, my guess it has to do with the a/c system maybe???? Please help

Some members have experienced vacum leaks in the environmental control switches inside the little console where the A/C controls are located. What you may be hearing is a blend door cycling.

There is a sticky on how to fix the switches for the DIY's.

I can only recommend a mechanic with experience in this type of troubleshooting/repair. If you don't have an extended warranty the cost will be several hundred dollars due to the amount of dissassembly required.

If you can repair it yourself then a Chilton's manual from your local library would be helpful.

There may be some help here on the site. Search using terms like Blend door, or A/C, etc.
