cruise control problems

[ThaiInfiniti]

Hey guys, every time I try to use my cruise control the lights will come on but it won't work. It will brake twice then turn off my cruise control. I have to turn it back on at the dashboard to repeat the process. Anyone else have that problem? Also where do I go to replace the Cruise Control Computer Unit if that's the problem? thanks.

good luck on fixing ur cruise control problem.. I just gave up on mine.. Mine would turn on from the on and off switch but would not arm.. So i just gave up

I take it none of you read the FSM AKA Service manual.

But try the simplest approach first, Check the fuses and relays.

Then replace the switch.

If all three are not the problem then read the FSM further or take the car to a dealer or someone with a consult who is qualified to work on Q45's.

Good Luck.
