Engine Performance problem
2005 Chevy Impala 6 cyl Front Wheel Drive Automatic 89500 miles

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?

Do you
have the same problem?
Yes
No

First thing to do is check the switch. Does the light on the switch come on when you press the switch? Does it stay on? See the trouble tree below:

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

Is there a small light in the steering wheel switch? If so, it should light up when you press the switch. Does it feel like the switch clicks and stays down when you press it?

I don't believe there is a light and the switch clicks, but doesn't stay down, but I don't think it ever did. I will check out the light and get back to you. Thanks.

Here is 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.
