Cruise control quit speedometer works

If you push on and set and nothing happens, the system may not be working properly.
You can get an owners manual on Ebay.

I don't have any advice on the cruise control, it would have to be checked out.
The same speed sensor on the transmission handles the cruise control and the speedometer. If it fails, the speedo would quit working and the check engine light would come on.

1st question, yes the spedometer has to work for the cruise to work or it has to at least get a signal from the speed sensor, if the problem is just the speedometer head then the cruise will still work, as a matter of fact that is how we test the system if when one of these come in the shop with an in-op speedometer we take them out and try the cruse if the cruse workes then we know the problem is just the speedometer head, if the cruse does not worn then it is a problem with the speed sensor or the control circuits for the speed sensor.

2nd question there is no way to bypass the the system to mke the cruise work yo dont have a speed sensor signal so the cruise has nothing to use a refrance in a way it thinks the car is not moving.

good luck, try replace the speed sensor in the transmission it might fix both problems.

Sure you can if a mechanic can do it so can you if you have the right tools and knowlege. First you need to know which one thers's one at each whell at the fround rear end housingf the rear rear end housing and the one in the side of the transfer case where the speedometer cable would'of connected on an older model and then theors three in the sides of the trans mission, Touque converter speed forward turbine speed output turbine speed. What proble are you trying to fix? the speedometer not working? Abs light on? Cheack engine light on? Cruise control not working? If the cruise control does work the speed senser is good and the check engine light will be on if the speed senser is'nt working. If the speed senser is'nt working the car will only take off in low and not shift to seecond or any higher gear as the computer doesn't know how fast the car is going. If the speedometer is'nt working and it does shift and cruise and the check engine light is'nt on then the speed senser is working but the speedometer is'nt if it is'nt and everything else is woring then as your driving hit the speedometer with your fist and see if it comes back on they can get stuck and i've fixed quite a few and they stayed fixed. On to wheel drive models with the rear wheels jacked off the ground safty I've run the car up to speed and trying wiggleing the wires and connectors till I wiggled the right thing till the speedometer came on ( including smacking the speedometer ) Just don't hit it too hard as it'll bust just like anything else.

It is most likely the speed sensor in the transmission.

Speed sensor from the transmission. If speedometer doesn't see it,,,,neither can the cruise control

Pretty common problem with these. Here's a guide to learn how to fix GM instrument clusters yourself, I used it to fix mine and it worked great.How to guide for Impala instrument cluster repair

The cruise-controls have 2-buttons that must be activated before it gets the car going when you remove your foot off the gas-pedal.
The cruise button is essentailly a switch that turns 'on' the cruise servo-motor that tells the sytems that you wants to use it, so it gets ready.
There are other three switches on the right-side of the steering wheel namely: resume accel; cancel; set decel.
To get your car to cruise: you must steady your speed and foot on the gas-pedal. You cannot just press the switches and expect the car to cruise. It takes about two-to-three seconds for the system to respond to a set cruising speed.
How to do it: accelerate to a speed of about 30-mph. Press the 'cruise' button on the dash first. Next you press 'set decel' button. This will turn 'on' the cruise control light on the instrument panel. Then wait a second or three and you would feel the cruise engagement. Any touch on the brake pedal will slow down the car and turns the cruise off. The 'cancel' button turns off the cruise light on the instrument panel.
If you hit the brake-pedal at any time for any reason, and you would like to continue cruising again, simply press the 'resume accel' button.
The cruise system works in conjunction with the braking system of the car. So all major parts of the braking system must be in good condition, otherwise the cruise system could shut off itself.

yes the transmission speed sensor has most likely failed, to confirm this have a trouble code test run

try replacing vehicle speed sensors. you need a good vehicle speed signal inorder for cruise and tha speedometer to operate properly
