Alldatadiy was zero help...I've researched this everywhere I can imagine.

I see the new modification that is recommended for this chassis but it doesn't make a great deal of sense. There are two yellow lines running from the back of the vacuum pump under the rear seat to the rear of the car. Then there are four more yellow lines running to the front of the car. Please forgive the blurry picture...if needed I can re-shoot them.

The new modification (see second image) shows only one line leaving the vacuum pump now and almost immediately the line conects into a T fitting that goes one way to the front and one way to the rear.

This thread is the closest to my issue but it doesn't address my issue exactly: http://tinyurl.com/29yuxc

The rear seat revealed a wonderland of lost crayons, quarters all manner sticky gooey gobs of stuff.

I have new flap actuator but I can't for the life of me find a description of how to remove it from the boxed in location Took out the right side amplifier and set it aside out of the way so that I can sort of see it.

Any ideas on where to start with the ol Mightyvac and what to try??
