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.

2005 Chevy trailblazer ext problems 1. Cruise will not set.worked last on 4/12/15 2. While checking fuses for CC problemdome lights stopped working, but worked fine before checking fuses. PLEASE HELP!


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/

New Toyota Etios, VD,KM 1100, observed thick white smoke from exaust pipe for @ 1 Min, while running engine on ideal.


the white smoke occurrence is due to unique Vehicle usageconditions like slow speed & Short trips drivingthe catalytic convertor is not able reach its optimum reactiontemperature. As a result, the Hydrocarbon accumulates in the Catalytic Converter.After sometime, once the saturation limit is attained, the accumulated Hydrocarbon
starts burning inside the Catalytic Converter. During this Chemical Reaction,Momentarily the white smoke is seen in the exhaust and is normal

2001 Jetta Tdi runs rough


Hi Whitneyford
Your priblem sounds more like the glow plug timer relay than the exhaust. White smoke after start up is a sign of diesel entering the exhaust before it has burned completly. This is as a result of the glow plugs switching off too early, which is usually caused by one or more faulty glow plugs or a faulty timer.With engine COLD, IGNITION ON... Check voltage with all 4 plugs connected. You should have a reading of 10--12 volts
If there is no power, check in-line fuse on loom coming to plugs.
If power is present, check for How Long. If only for a few seconds, the problem is with the timer. This unit (the larger of the relays and usually black in colour) is fitted on the fuse board, and there are a few different types. They come in 7 pin..8 pin..and even 9 pin units.
The glow plug light is often NOT accurate (even with a new timer unit fitted) as to the time of heating, and you will almost certainly find that power will flow to the plugs for quiet some time after the light goes out. This is not unusuall with The Jetta Tdi.
Good luck.
I hope this helps you sort out this problem

Jetta tdi 2007 running rough on start up at times. blowing excessive amounts of smoke from exhaust at times. poor idle at times feels like running on three and a half cylinders, takes a few seconds too...


You may want to check the ignition system. The smoke could be because of unburnt fuel. You may be running on less then 4 cylinders. Check if all spark plugs are firing. You may also want to use a scanner if there are error codes found in its ECU.

Momentarily Sluggish Acceleration


Are you loosing power to the ecu when the car is shut down? most cars with an ECU that controls timing, fuel, or boost can be forced to relearn the car if the ECU looses power (called a "limp" mode). I'd look into this. Also are you getting any check engine lights? considering the description of the problem, this would help to diagnose. Try getting the car started and running normally, then turn the car off but do not kill the power to the car, just stop the motor from running...Fire the engine back up and try to give the car a good stomp on the gas and see if you get the same sluggish problems...my 2 cents... Good luck future auto DIY's

Yeah this could definitely be the fuel filter, change it yourself and save the cash, it's pretty easy, although you may spill some fuel.
