Ok heres the deal saturday my cruise control died I checked the fuse and its fine so my car still being underwarrenty I take it in to my dealerships shop. Now just to get you up to speed my DRL's are disabled and I have the Toyota Cavalier tails in my car with jumper wires to the front turn signals to work the rear ones. So the kid they have working on my car says the taillights are the reason the cruise won't work. So I asked him if thats the reason then why has it worked for all this time and just went out now ?
He says he doesn't know and that he has 2 hours on my car and can't figure it out.
Supposedly the switch in the column is good and both the clutch and stop light switches are good and the mod is getting power and he has no codes.
Does anyone have any ideas at all ?
Now keep in mind no fuses are blown anywhere all the lights work fine. So how could the Toyota tails make the cruise not work?
Semper Fi SAINT. May you rest in peace.
Fun update! They want me to re-wire the tail lights back to stock because they are so sure the Toyota tails are the cause. Well what else can I do right ? But what I do not understand is IF the tails are indeed the cause for the cruise not working then why did the problem take a year to appear ? Or if a wire did indeed rub thru and ground out for the turn sig bulbs wouldn't that blow the fuse or stop the bulb from lighting ? Either way again I would be able to see that !
I do not understand this and if ANYONE has had this issue, or if you have the Toyota tails and have never had this issue please can I hear from you as this is driveing my
nucking futs !!!

the tail lights don't have anything to do with the cruise control. The only one would be the brake light that "could" cause a trouble. Otherwise lift the car, let it run at 30mph on the lift and put the cruise. Check the wires and check if the calbe is broke or stuck.

Good idea about the cable I'll check when I get off work. I thought the same things about the tails but my service dept says they can't find anything wrong so its gotta be cause of the tails. So they want me to put it back to stock before they'll go any further on it.
Of corse I'm gonna check the cable first and if its broke I'm gonna laugh at them. thank you and I'll let you know what I find.
Semper Fi SAINT. May you rest in peace.
Well the stock cruise control is wired to the VSS, maybe the connecting came loose.
/\ /\ /\ But wouldn't that shut off the speedo ?
Semper Fi SAINT. May you rest in peace.
Yes it would.
Is the control working? The switch could be shot too.
The "technician" at Gm are mostly guy that don't know s*** about cars. 2 of them took 3 hours(they were working together and they were using the computer to find the sensor) to find a freaking bad connection for the knock sensor on my 02 Z24. They didn't know where the sensor was. Plus you pay 70$ an hour for those loosers? I know more than them about my cars than they do and I'm not using a computer to tell me what to do.

Well I'll tell you what the "tech" told me. All the switches have power they all check out the module has power and there are no codes so I don't know why it won't work. The service adviser said they called the GM tech support hot line and the first thing they asked is if I had altered the taillights in anyway. When they said yes the tech support said return the car to factory and call us back. So I'm screwed I have to re-re-wire it back to stock and stick the stock tails back in the car so tech support can help the clueless tech working on my car. Great huh ?
Tho I am gonna check the cable cause if its broken I'm gonna smack someone in the head!
Further proof that here at Miller Brothers Chevrolet we are an equal opertunaty employer as we hire ONLY the best window lickers as techs. God help me !!

Not always.
If the cruise control is stock, possibly. But on the car i took my cruise control off of, which was also stock, the VSS ( i contacted you guys about it, its relevant here ) had 2 wires connected to the same point. So 1 wire ran to the cluster, and the other for the cruise. So if the cruise side came loose or shorted, it would not affect the speedometer.
Vehicle's Speed Sensor:
The Vehicle Speed Sensor (VSS) is mounted to the transmission and provides a low voltage Alternating Current (AC) signal to the Cruise Control Module (CCM). The CCM converts the AC signal to a pulse width modulated Direct Current (DC) signal, which is sent to the cruise control module at a rate of 4000 pulses per mile.
Cruise Control Module:
The cruise control module has to do three things. First it remembers the speed you set. It stores this set speed until you change it or turn off the ignition. Next it takes the speed signal from the vehicle speed sensor and compares it to the set speed. Lastly it sends pulse signals to the actuator. The actuator will move the throttle linkage to bring the vehicle up to the set speed and then modulate vacuum to maintain that speed.
Actuator:
The actuator is what actually moves the throttle linkage. It is most often vacuum operated although some actuators are electrically controlled with small, stepper type motors. The actuator moves the linkage as directed by the cruise control module until the set speed has been achieved. It then maintains this speed by controlling the amount of vacuum. It actually modulates the vacuum as the pulses from the control module direct.
Brake Switch:
The cruise control release switch and stop lamp switch are used to disengage the cruise control system. A cruise control release switch and a stop lamp switch, mounted on the brake pedal bracket disengage the system electrically when the brake pedal is pressed. This is accomplished by interrupting the flow of current to the cruise control module. The cruise speed of the vehicle at brake actuation will be stored in the cruise control module memory.
Clutch Switch:
In addition to the brake switch, a vehicle with a manual transmission has a switch very similar to the brake switch and disengages the cruise control system when the clutch pedal is depressed.
Throttle Linkage:
The actual mechanical connection between the cruise control actuator and the engine throttle.
What Can Go Wrong
Since each manufacturer has slightly different cruise control systems, specific troubleshooting procedures will vary. Most vehicle shop manuals have a multi-page diagnostic flow chart that the dealer mechanics use to solve failures. If there isn't an obvious problem like a broken wire, a blown fuse or a leaking vacuum line then the problem most likely lies in the brains of the unit or in the switch that sets the speed and contains the other functions of resume and accelerate.
But since each system has the same basic parts, different systems will share the same basic problems. As always, you should consult the repair manual for you particular vehicle before trying to troubleshoot your cruise control system.
If the vehicle speed sensor fails, the cruise control module will not get a speed signal. If this is the case the speedometer will usually stop working as well.
The cruise control module can go bad and either not understand the signal coming in from the vehicle speed sensor or is unable to send the signal to the actuator. In addition blown fuses or broken wires can prevent the cruise control module from working properly as well.
The vacuum diaphragm inside the actuator can develop a leak and prevent it from operating properly. If it is a large vacuum leak the actuator will probably not set at all. Leaking or broken vacuum lines are usually the major cause of this problem.
Lastly, the linkage itself may break or become disconnected. Some cruise control systems use a bead type chain, like the pull chain on an old light socket, and they just plain break.

It seems to be GM's policy that anything wrong with your car is the immediate result of any modification you may have done, regardless of how completely unrelated the modification is to the problem.

i honestly think it willbe the Cruise Control Module. Seen as how GM hires techs about as smart as their designers, they're window lickers must not realize that if you have power to the moduke (main power and control power) then the cruise will work, if the module works. Having modifed TURN SIGNAL wiring will NOT afftect cruise. modified BRAKE light wiring MAY, but only if the brake pedal position switch wiring is tampered with.

Ok so I tried the sugestion of jacking up the front and trying the cruise and low and behold it worked fine. Drop it down and try to do while driveing and zip! I'm thinkin maybe ABS wheel sensors for the rear or something along those lines. I undid all the tail light stuff and NO DIFFERENCE !! DUH ! Like we all didn't know that would happen right ! Well Tomorrow I stick back the factory tails and take it in on monday.
OH BTW, The cruise worked when I left work Friday but died halfway home. Looks like its not the tails.
Well I'll post what the wonder techs find out monday.

Well after 4 efing days and me haveing to remove every aftermarket electical piece, includeing my AMP and sub! they finally found the cruise modual itself was burned up!
And that it also fried part of my PCM !! So they replaced it all under warrenty and now I have cruise again. But now I get to have to put all my sh-t back in and hook it up !
Why the hell couldn't they figure this out without my needing to remove my amp ? Go they are morons !!
Semper Fi SAINT. May you rest in peace.
