I have an '03 track 350z. Cruise control in not working at all. I have checked all the fuses. The horn still works. When I press the cruise control button the light does not come on or flash or anything. I went all through the manual and checked a bunch of other threads. Now I don't know if the module itself is bad, because I've head the CEL comes on when something is wrong with it and my CEL is not on and I have no codes or anything. (I have tested the cluster bulbs)....



I am taking it to the dealership next weekend but I feel like they'll pretty much want my entire left leg to fix it so I'm seeing if I can get help here first.

 

maybe one of the sensors. brake or clutch if it's manual.

 

It is manual, sorry. I did check the clutch sensors as far as I could with my youtube mechanic knowledge. I didn't even think about the brake senor. Smart me

 

how did you checked the sensor?

 

Well like I said, youtube mechanic skills. Looked at the sensor, decided the clutch feels good at 74k miles. Ha, how do I go about checking it? I'm leaning more towards it being the brake sensor.

 

I called the dealership. Since the light doesn't come on at all it's not a sensor. This means it's most likely a fuse. Does anyone know exactly what fuse does the cruise control on a 350z??

 

i have 2003, my cruise control also went out a couple weeks ago. i was also having power issues.

my solution was replacing all the tail light bulbs! as soon as i put new bulbs in, bam worked.

there's some whack electrical engineering going on with our cars, i would check your tail lights, do you have oem lights? are all the lights working?

 

My tail lights are stock and all my lights work. I have HID headlights though. I need to know though, when you have the clutch pressed, will the cruise light come on at all? Does it come on and just wont let you set a speed or not come on at all?

 

Just got a code for a crankshaft position sensor, idk if that could have something to do with it? Getting that fixed asap

 

The cruise light would come on, but it wouldn't let me set it. the set light would just start blinking.

 

Thanks
