The cruise control works off of a vacuum diaphram. It could be leaking or a hose to the diaphram could be leaking. There is also a rod from the diaphram to the throttle body that could have come loose.

Cruise control stopped working


no year stated, wow.
the first checks are not the CRUISE.
they are:
1: all fuses good.
2: CEL lamp out driving, if not the PCM will in fact cut Cruise function ( preventing TOYOTA SYNDROME)
3: scan tool do a full PCM scan, got errors. got DTCs, bingo.

today cruise is the last to work, (a very serious safety issue)

2003 Lincoln ls v-8 cruise control won't engage. Light won't come on or anything when I hit the button. Everything else work fine.


My 2001 Lincoln ls cruise control will not work. Put in a new clockspring and that did not fix it. radio controls and horn work but the air bag light stays on continually after starting. The lights on the cruise side will go on an off -I have bought that part to replace but don't want to put on if that is not the problem.

My cruise control was working fine until my transmission went out and I replace it on a 1994 ninety eight oldsmobile.


Follow the vac. hose from the cruise servo to the three way connector. They usually fall apart and need to be replaced. No vacuum no cruise!
