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.

My air conditioning system comes on automatic why does ir do that


It may be normal, depending upon what you are doing with the car's ventilation system. Most newer vehicles will use the A/C when the ventilation controls are set to the DEFROST position in an attempt to avoid the fogging that can occur in side the glass when defroster is first turned on. Check the switch setting that you have the ventilation system set at. If there is a snowflake symbol there, it indicates that the A/C unit will activate when in that position. If the A/C is turning on by itself at other times, it may be a malfunction in the system.

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/

2007 chrysler 300c cruise control wont lock in and hold speed says i ts on the dash but is not engauging


.
Hello, "arthur o'neill".
Your car has parts under the hood to engage and control the throttle.
Those parts, as well as others, such as the speedometer,
and its cable must all be working properly,
for cruise control to work.
Either take it a mechanic, or get a 'shop manual',
for your particular model.

I have two questions: 1. What should I do about a power AC outlet in the dash that's not working? 2. What should I do about my cruise control not working at all?


Below are the 4 main components to the cruise control system, you can use these to troubleshoot why your cruise isn't working.

I would check the fuse panel for both problems before hand though, could be a simple fix

Vacuum System (including pedal switches and pump)
This is the most common source of problems. For testing, you'll need a way to generate and hold vacuum in the lines. A good tool for this is a miniature Mity-Vac type of device.
Wiring
Most common wiring problems in this circuit occur in the wires going from the steering column, down the turn signal arm, and into the switch. There is also wiring for the vacuum pump that may need to be checked. Steering Column Switches
Not usually a problem, but wiring in steering column can be. Control Unit
This piece rarely goes bad, so it should only be suspect when all other common problems have been ruled out. The easiest way to test it is to put in a known good unit.

2004 gmc 1500 sierra heater control stuck on


Defrost is the default position. Is the control a autyomatic temperture control unit? ( you set the temp and select automatic) if it is the system is completely electronic. You push the buttons and the control still says defrost or can you select something else and the control shows it but it just keeps coming out the defrost? If the control changes and the air comes out the defrost anyway and the cheack engine light isn't on, then the problem can be blown fuses or an air door actoater not working. Does the dash emit a clicking sound? if it does with the covers off the bottom of the dash reach around touching the different pieces till you touch the idem that is clicking. this is an acutor motor, or blend door motor. they have gears in them that wear out and break the motors aren't repairable and you just replace the ofending motor. the door that is moves can be stuck. and may have to be freed up with blaster, WD40, or other rust buster till it moves easy. maybe after getting the door to move smoothly you can get the old motor to move the door wiithout having to install a new one.

The read out on dash says service electric brake system,brakes seem to work ok and when i select cruise control it will not set


Do your brake lights work? Your cruise is tied in with your brake lights. If your brake lights are stuck on or there could be a bad switch or bad wire on the switch then your cruise wont work.

I have a 2008 Honda CRV and for the life of me I cannot engage the Cruise control- I press the Cruise Button on the right of the steer wheel and nothing happens - nothing Help anyone ? Tks Nancy


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.

2001 Jeep Cherokee a/c blows defroster only, no cruise control


There is a vacuum leak under the hood somewhere. Check the vacuum at the speed control servo. If there is no vacuum on the line with the engine running, follow the line to find the leak. The vacuum reservoir is mounted under the battery tray. I would look in that area after confirming no vacuum at the servo.

Cruise control does not work on 2005 Rubicon. Light on dash work , but cruise control doesn't


On my 05 Wrangler Unlt'd Ruby - The vacuum hose on the drivers side of engine had come off, which disengaged my Cruise and the actuator which determines whether my heater points to the vent, Defrost or feet. Put it back on and secure with a cable tie.

If it is like mine, you will then have idling problems, especially when coming to a stop. You will need to clean the throttle body because the engine has picked up **** through the open port while it was off. Directions for that exist on this site elsewhere.

All of these are easy - i hadn't worked on a car in >25 years and it took me 30 min.
