first pull off the line going to it and if it has fluid in it change the modulator. Next, take the modulator off and apply vacuum to the line and stick a screw driver in the end of the modulator and see if the diaphragm moves the valve inside. If the valve doesn't move, replace the modualtor.
- i am assuming Ford but also you can pull the vac.line off of carb.or wherever it draws the vacume from without getting under car and check for fluid at that point
Consider getting yourself a service manual as it contains many troubleshooting for your car. Comes very handy sometimes.
