Is the cruise control on the 2005 Chevy Impala a module that I can replace or is it more involved? If it is a module, where can I get the part number and about how much would it cost?

The light on the dash does not come on. I press the button on the steering wheel, but nothing happens.

Hey ANG74,

I would test the fuse first to see if it is good.

Here is a guide that will help you.

https://www.2carpros.com/articles/how-to-check-a-car-fuse

There is a wiring diagram at the bottom of this post.

If that tests okay here is a a trouble tree, please follow:

Proper operation of the brake lamps. Refer to Exterior Lighting Systems Description and Operation in Lighting Systems.

The throttle linkage is not binding.

The cruise control release switch is adjusted properly. Refer to Cruise Release Switch Adjustment .

The stop lamp switch is adjusted properly. Refer to Stop Lamp Switch Adjustment in Lighting Systems.

When testing vehicles equipped with steering wheel controls, the steering wheel must be rotated to each stop position while testing the cruise control signal circuits. This will assure the integrity of the (SIR) coil.

It could be anything from a wheel speed sensor to an input or output sensor to an electrical issue.I would have to suggest that you take it to a shop and have it diagnosed. Because there are a lot of very specific tests that will need to be done to get to the root cause.

For the past 2 weeks everytime I start my car, the security light comes on and I can hear a couple of clicking sounds. The car still runs but now my cruise control dosent work and I am only able to control my power windows from the drivers side only. Is this something I can fix myself and if so how?

A couple of days ago I was using my cruise control and have not been having any problems with it and the next day I tried to use it I got nothing. My husband checked to see if it was the fuse and the fuse was fine. What are my options? What else could I check? Is it something that we can fix or do I have to take it to a mechanic?

The cruise control on my 03 Impala works intermitently. At first it worked almost all of the time. Now it is working less and less often, to the point that it is unusual that it does work. The map lights also have an intermitent problem. Everything else seems to work fine.

It could be a bad cruise on/off switch or a bad ignition switch.
