Get to a dealer and have them check your cruise control. The first recall was for an inline fuse. Now they are finding that electrical problems are showing up with false dash indicators. It can affect brake lights and trans shifting.

If you want to check out the ABS, some Autozones and Oreillys have scanners for that special plug. If not, a dealer will.

I ve got a kalos 1.4sx 2008 and i ve got problems with the brakes. The brakes ''crunch'' when i m bringing the car to a halt,even on dry roads. The abs warning light has been on a couple of times but...

The Chevrolet/GM autos rely on a Kelsey ABS actuator system that is electronically controlled. I know its hard to describe sounds, but is it possible the crunch is a hum? If the ABS light comes on and goes off after restart it means one of two things. That the ABS controller is going bad or the speed sensors on the wheels have come loose or gone bad. Under your hood there is a fuse compartment that contains the fuse that controls the ABS system on your vehicle. Its a 60 Amp fuse and large.. Look in your owners manual for its location. . Check it with the vehicle OFF to make sure its not blown or cracked. Leave the fuse disconnected and start the car. The ABS light should STAY on as well as the parking brake light. Test your brakes by pressing down on them while the car is in park and not moving.. do you hear the sound. If you DONT hear the sound then the ABS control module is causing the brake pump to work continuously and thus your "noise". YOu can confirm by placing the fuse back in place and then listening to the car about where the drivers door is... do you hear a hum? If so you can leave the fuse disconnected to deactivate the ABS module. The brakes will still function you just WONT have ABS capability. Confirm this with a very slow roll from park or neutral and press brakes to stop. If you dont hear the noise or a hum, reconnect the fuse and take the car for a drive. Turn to the left and right while applying the brake at an intersection.. vehicle in motion slightly. Do you notice that the ABS light or noise occurs turning one way or the other or both? If it comes on during the turn then the ABS sensor in that wheel or both wheels need to be inspected and possibly replaced. Finally, you need to inspect the brake pads for wear..typically however brake pads have WEAR INDICATORS built in and will start to SQUEAL when you apply the brakes telling you time to replace pads. If its a squeal and not a crunch then have pads replaced. Finally, be sure and make sure you dont have any rocks or road debris within the brake area or between teh pads and the rotors. That would be your final area to review for a CRUNCH noise.

My battery keeps dying on my 2004 cts

Unfortunately there could be many causes for premature battery death. The top culprits in ALL cars would be a bad alternator that isnt putting out proper charge to recharge the battery, a bad battery itself (if yours is factor and never changed then its time), or you could have poor connections. Then there are some GM specific things such as a bad Brake Control Module, Bad Fuel Pump, etc. Lets start with easiest first. If you are not handy or dont feel comfortable under your hood then there are alternates to the below

1. Check the battery cables at the battery posts (yours is side mount) and make sure they are tight, wont wiggle or twist back and forth. If they do tighten them

2. Check the alternator wires to make sure they are firmly attached, no loose nuts or bolts, etc. Tighten but dont over tighten and strip or break

3. Check for corosion on battery, battery tray, battery cables. These can drain the battery. If you have corosion then you can purchase CRC battery cleaner with Acide detector at local parts store to spary and clean.

4. At night go to your car and see if any lights, such as glove box, trunk, hood, dash, etc are staying on. Sometimes trunk or glove box lights stay on but since we dont look in either often we dont notice.

5. Crank the car and have someone stand in front as you are in the drivers compartment. Turn your lights on and then bright. Depress the brake pedal and ask the person if the lights dim or flicker at all. Also look at your instrument panel and see if your lights there are pulsing, etc. This can indicate a bad alternator

6. Turn on radio and see if you hear a hum (not static) but a low hum or whine. This could be a bad alternator.

An alternator has DIODES in it and they can go bad causing it to fail.
An alternative to above is to take it to your local Autozone, Advance, Napa, or Oreilly auto parts store and they can do a "load check" on the battery and alternator to see if they are functioning properly as well.

Now for the GM issues.

GM cars are known, even the Corvettes and Cadillacs, as having bad fuel pumps, Climate control, and ABS sensors.

1. ABS control module can go bad. A common diagnosis is to listen and see if you hear a hum comin from middle to rear of car on drivers side, near rear wheel well, CAR OFF. If the car is off and you hear this hum. Its possible the ABS module is bad and will need to be replaced. They are very expensive to replace unless you find a reputable place to have yours rebuilt. If you are a GOOD DIY person and comfortable with cars a good site is You can disable the ABS module by pulling a fuse in the engine fuse block. Im not sure the diagram for your model. Check your owners manual.

2. Fuel pumps can also go bad and continuously run. If its running it will drain a battery. You may not have symptoms in the running of the car if fuel pressure isnt affected. Listen for a similar him in same area (mid to rear) of car. Hum will be with car OFF

3. Climate control in your Caddy is very advanced and uses a climate control module and not typical switches and wires. All computerized. If you've noticed a change in performance of your fan output (low air output or higher output at lower settings) Change in air temperature and temp not matching what you have set on the control Cold=Cold.. Hot=Hot.. then its possible this is a drain.

Unfortunately the last three are somewhat easy to diagnose, but hard to fix. YOu will require a good mechanic or your dealer for these repairs.

FYI.. the same site for your brake module rebuilds teh climate controls as well.

Good luck

Abs system humming even with the truck off. Had to pull the fuse to get it to stop humming. Of course, no abs now

The abs control module has an internal open circuit. You should go to a repair shop to have it changed out. very common

There is an ABS fuse under the hood that you can take out, and the noise will quit. The noise is accually your ABS pump. They are kind of expensive.
