Hi there,

I have a '76, 280c and have some problems with my CC.

The actuator has 2 lines, 1line(picture nr 6) is for vacuum and runs to the intakemanifold and the other is .............................(see picture line 5)

Can anyone tell me where the otherone is runnnig to/from

The second line is a vent which will probably go though the firewall into the passenger compartment.
Cruise problems are usually caused by the control module but can also be caused by stop light bulbs, speed sensor, steering column switch, throttle actuator.
