Cruise Control Relay

[phil1]

I have a 1999 2.3 Galaxy Ghia. Cruise control has stopped working. Tried the usual pipe check and all seems to be OK, holding a vacuum and moving the accelerator pedal. Tried the vacuum pump which is clean inside, no water, and works off the car. Checked the swithes at the brake and clutch and they both seem to work. When switching on the CC there is a clicking noise from behind the dashboard under the radio. The click occurs when you move the switch far to the left and again when you release the switch. I beleive that this is the relay but not sure. Is there a relay, and exactly where is it? Anyone any suggestions. Need some help as going on a long drive to France next week.
