S90 Part ID & Cruise Control Servo Question?

JETEXEC · Post by **JETEXEC** » 13 Jul 2013, 14:05

1997 Volvo S90 Questions:
What is the Part in my Photo and what does it do?
Also, I replaced the Cruise Control Servo due to failure and now system does not accelerate as before.
Is the Servo adjustable?

Thank you in advance,
RM

The pictured device appears to be the alarm horn but I have never even had the hood up on a S90. I am going to move your message to the appropriate forum so you can get a model specific answer.

It is the alarm horn.

The cable from servo to throttle cable spool is adjustable.
Is the replacement servo used? It could have a pinhole.

Jimmy57, It is a new servo.

It is a simple system. A air pump located on the inlet side fender, a black double sized relay located behind the console, the servo (which is new) and a cutout switch (which I believe acts off the brake switch)

Have you checked all these items? My 960 had a pinhole in the servo (or diaphragm as it's known) which I filled with gasket sealer.
