Installation of cruise for Pontiac G5

None, just replace the switch. The flashers are controlled by the Body Control Module and you can't disconnect that.

Cruise Control on your vehicle is computer controlled , having the vehicle checked for DTC'S - diagnostic trouble codes should be the first step in diagnosing this problem . Not a code reader or autozone etc... Would need a factory Tech 2 scanner or someother professional type , one that can read BCM - body control module codes .
Cruise control is a speed control system that maintains a desired vehicle speed under normal driving conditions at 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 accelerator pedal
• The brake pedal position (BPP) sensor
• The body control module (BCM)
• The cruise control on/off switch
• The powertrain control module (PCM)
• The + RES switch
The + RES switch is the equivalent to an accel/resume switch.
• The - SET switch
The - SET switch is the equivalent to a set/coast switch.
• The throttle actuator control (TAC) module
• The TAC motor
• The vehicle speed sensor (VSS)

The dash won't work with the battery disconnected

Tricky. If you're unfamiliar with the operation of GM cruise control systems, refer to a qualified GM technician.
Things you can try:

1. Lubricate the actuator switch;
2. Lubricate the brake switch (yes, the brake switch is in the circuit);
3. Lubricate all actuator switches for the cruise control system at the steering wheel;
4. Check for vacuum leaks, damaged vacuum lines, or other visible problems around the cruise control servo (under the hood).
5. If your vehicle is equipped with a TRIP COMPUTER, and the trip computer is not updating mileage, replace the SPEED SENSOR.

IT'S IN YOUR MANUAL!!!

I have installed car audio equipment for over 40 years on end off.There is no fuse for the speakers.Who ever told you that doesn,t no what in the (Hell) they are talking about.

If the cruise control makes the engine seem to run very rough until disengaging it, there could be a problem with the engine itself. As, most cruise control systems just pull on the throttle cable to maintain speed on the highway based on setting the speed with the button.

So, I would look into the engine maybe having an issue with spark plugs, or wires, or another tuneup or mechanical issue.

   • The cruise control cable to the module

you can have two things wrong with your car 1 a/c control head is bad. 2. temp blend door actuator is bad. change actuator first. make sure you install it before you plug the connector.

you will require a new steering wheel.
and it is almost $500 from the dealer.
It will look like this...


The aftermarket one does not stick off the handgrips of the steering wheel - it is on the bottom Hub area.


The aftermarket uses a wireless transponder and the brain is hard-wired into the ECU (computer)

Im not sure that your vehicle has the existing wires in the harness to facilitate adding a cruise in the steering wheel without replacing the entire steering column... or wiring harness.

Im sure with the right amount of $$ it can be done - but the aftermarket one is the least invasive and cheapest route for you.

All the cars... cobalt, g5, g6, g7 etc... have the cruise control built in the ECU, and it simply needs to be turned on using the GM Tech Tool Candi II. Its the part about switching it on and off that the costs are involved.

Go with the aftermarket - its really not that bad!

Not really sure on parts pricing (probably very expensive) but very complicated and work intensive to install... Need to get the engine computer reprogrammed for cruise control, install all the wiring (to the brake light switch, the speed sensors, etc...) install the servo/vacuum motor and cables to the throttle assembly...
