Chrysler Repair: Sebring 2005 cruise control, throttle cables, fuse box

Question
After servicing the cruise control does not work. It was working perfectly even on the way to the service station. The cruise light goes on but the system does not respond. Any ideas?

Answer
Hi Abraham,
If the electronics appear to work I would still check fuse 7 in the fuse box under the dash (this suggestion is based upon my '03 manual as I don't have one as new as '05). The other operative source for the system is vacuum, generated via a hose between the intake manifold and a vacuum reservoir attached to that, and a hose attached to the vacuum reservoir that goes to the speed control servo which actually operates the throttle cables that maintain the speed. It is reasonable to find the servo (trace the cables attacked to the throttle body: there will be at least 2, one from the gas pedal and one from the speed control servo; have a helper operate the gas pedal so you can find the cables in question) and then inspect any air handling lines attached to the servo to see if they are disconnected or cracked so as to not hold a vacuum. Also look for any nipples on the servo which are open to the atmosphere as they may be related to a hose that has been disconnected.
I would, if that is unsuccessful, bring the vehicle back to the servicer and because they know the regions where servicing was done they may be able to identify some aspect of the system that inadvertantly was disturbed by the work that they performed.
