Question about 1994 Chevrolet K1500

2 Answers

My cruise control in my 1994 chevy 4x4 half ton works intermittently, ie) coasts for 5 seconds, accelerates for 5 seconds. when it's accelerating there's a buzz coming from under the dash, and late one night when i was driving i noticed the 3rd brake light flickering on when it was 'accelerating'. i know they're somehow related, but can someone help me get onto the right path of what to look for under the dash or whatnot?

Where is the fuse for cruise control on a 2003 envoy


It is HVAC 1fuse #39 in the rear fuse block ,this powers the on/off switch for cruise control ! Fuse Block - Rear Beneath the left rear seat. What engine does it have ? 4.2 L or 5.3 l There is no vacuum involved in the operation of the cruise control ! Your vehicle has electronic throttle control .
Cruise control is a speed control system that maintains a desired vehicle speed under normal driving conditions at vehicle speeds above 40 km/h (25 mph). Steep grades may cause variations in the selected vehicle speeds.
The following are the main components of the Cruise Control System:
?€¢
The powertrain control module (PCM)


?€¢
The On/Off switch


?€¢
The Resume/Accel switch


?€¢
The Set/Coast switch


?€¢
The TCC brake switch


?€¢
The stop lamp switch


?€¢
The throttle actuator control (TAC) motor


?€¢
The vehicle speed sensor


Cruise Control Engaged
The cruise control system will engage and adjust the vehicle speed based on the activation of the following cruise control switches:
?€¢
On/Off


?€¢
Resume/Accel.


?€¢
Set/Coast

The cruise control switches are located on the multifunction/turn signal lever.
The powertrain control module (PCM) monitors the signal circuits of the cruise control switches in order to determine when to capture and maintain the selected vehicle speed. The PCM uses the throttle actuator control (TAC) module motor in order to control the vehicle speed. For further information on the TAC System, refer to Throttle Actuator Control (TAC) System Description in Engine Controls - 4.2 L.
Ignition positive voltage is supplied from the 10 ampere HVAC 1 fuse to the cruise control switch via the ignition 3 voltage circuit. When the normally open cruise control On/Off switch is turned On, the switch closes and the PCM detects a high signal voltage on the cruise control on switch signal circuit. When the normally open Set/Coast switch is pressed, the switch closes and the PCM detects a high signal voltage on the cruise control set/coast switch signal circuit. To engage the cruise control system, turn the On/Off switch On and momentarily press the Set/Coast switch. The PCM will confirm that the cruise control enable criteria has been achieved. The PCM will engage the cruise control system and record the selected vehicle speed. The PCM sends a class 2 message to the instrument panel cluster in order to illuminate the cruise control indicator. Pressing the accelerator pedal, while the cruise control system is engaged, will allow the driver to override the cruise control system in order to accelerate the vehicle beyond the current set vehicle speed. When the accelerator pedal is released, the vehicle will decelerate and resume the current set vehicle speed. The driver can also override the current set vehicle speed via the Set/Coast switch and the Resume/Accel switch. When the cruise control system is engaged, pressing and holding the Set/Coast switch will allow the vehicle to decelerate from the current set vehicle speed without deactivating the cruise control system. When the Set/Coast switch is released, the PCM will record the vehicle speed and maintain the vehicle speed as the new set vehicle speed. When the cruise control system is engaged, momentarily pressing the Set/Coast switch will allow the vehicle to decelerate at 1.6 km/h (1 mph) increments for each time that the Set/Coast is momentarily pressed, with a minimum vehicle speed of 37 km/h (23 mph). When the normally open Resume/Accel switch is activated, the switch closes and the PCM detects a high signal voltage on the cruise control resume/accel switch signal circuit. Activating and holding the Resume/Accel switch, when the cruise control system is engaged, will allow the vehicle to accelerate to a greater vehicle speed than the current set vehicle speed. When the Resume/Accel switch is released, the PCM will record the vehicle speed and maintain the vehicle speed as the new set vehicle speed. When the cruise control system is engaged, momentarily activating the Resume/Accel switch will allow the vehicle to accelerate at 1.6 km/h (1 mph) increments for each time that the Resume/Accel switch is momentarily activated, with the maximum acceleration total of 16 km/h (10 mph) over the current set vehicle speed . Momentarily activating the Resume/Accel switch, after the cruise control system has been disengaged by pressing the brake pedal, will recall the previous set vehicle speed that is recorded in the PCM.

Why does cruise control continue to accelerate when engaged?


If it is disengaged to coast (to a lower speed), it will accelerate to the previous set speed when reengaged. This is experienced often when driving on highways and you have to coast to a lower speed.

Bummer deal! This may be a way to tell you some tail lights are burnt out. Some cruise controls have a fuse in a second location.
The fuse is not in right or is blown. Check with a new fuse. Hope this helps. ...gc http://www.auto-tune-up-and-repair-options.com/

I have a 2005 Ford Taurus and my cruise control has not been working for about a week now. The cruise control light is "ON" but it is not engaging? Also, the day after my cruise control stopped...


open the hood and check to see that the throttle cables are not out of place, if everything looks ok then unhook the cruise control cable from the throttle body (black plastic end) by pulling up on the cable end. this will disable your cruise control from making your car accelerate at unwanted times. sounds like there may be a problem with the cruise control servo.

I want to know how to use my cruise control in my 1994 Toyota pickup. It has all the buttons and the capability but the words are scratched off and i don't have a manual.


Generally... There is ON/OFF - SET - ACCELERATE/RESUME, COAST/DECELERATE. Cruise is available at speeds above 35mph or so. Sometimes there is no main on/off. Cruise on a turn signal stem has a button that pushes in on the end, push when at desired speed. resume/accelerate slides to right, is spring loaded and return left when released. the same lever when slid left is coast/decelerate. Momentarily sliding accelerate and releasing increases crusing speed by a couple mph. If brakes are used cruise disengages, sliding resume returns you to cruise speed after braking. Coast/decelerate disengages cruise, when at desired lower speed hit set. On some, hitting set not needed, when coast is released speed is maintained. Variations may be up/ down instead or may be steering wheel face mounted. Please rate answer. Duct tape is like the force, it has a dark side.. a light side.. and holds the universe together!

What are the functions of Resume &Coast buttons in steering wheel


If set at a specific speed and you have to slow down by hitting the brakes, The brakes turn off the cruise control. Pressing resume automatically turns the cruise control back on and accelerates to the previous speed setting. You can also use it to accelerate and by releasing it the new speed will be set.

Cruise control how to use


Most cruise controls are designed to disengage when you press the brake pedal. I always mention this first because people tend to try to press the clutch pedal while the cruise control is engaged and this startles them when the engine revs up all the way...

Anyway, to use your cruise control:

1) Press the Cruise control button to on.
2) Drive up to the speed you need to go.
3) Press the "Set/Coast" button.
4) let go of the accelerator pedal

If the cruise control system is operating correctly, your vehicle will continue to travel at the same speed until you either press the brake pedal or you cancel the cruise setting with the cancel button of the cruise control.

Remember: Your civic is not equiped with a radar system for your cruise control, so if you are aproaching an intersection or traffic in front of you, do not expect the car to know it needs to stop. Also, cruise control only operates the accelerator pedal i your car, it is not autopilot, so it will not steer your car for you.

(you think it sounds silly that I am writing this? You should see my friend's car... He thought Cruise control was like autopilot, so he smashed his brand new civic into a tree...)

Happy Motoring!
