You may have disturbed the wiring down by the ignition switch. In any case, the brake pedal switch near that switch is now either misaligned or broken - try fixing that first.

Yes. Any general motors garage can fix it. The parts are the same for all models current or not.

Does the security light come on an stay on when it won't start ? The powertrain control module (PCM) will disable engine starting.

Coolant leaks on the path of least resistance, in this case it's the cap to the coolant reservoir. Overheating is caused by a few things: 1. Bad water pump 2. Clogged thermostat 3. Bad fans May want to check a few of these components.

Plugged catalytic converter ?

Accelerator cable may be sticking and not allowing the throttle to fully close when there is no pressure on the gas pedal. Check the cable at the throttle body to make sure the throttle is fully closing. This can also because by a faulty idle air control (IAC) motor.

This is one guy's advice: Replace the speedo head, that should take care of the problem." This site is also interesting because the guy said General Motors cars had instrument cluster problems from 2003 through 2006. When I researched instrument cluster problems on the Internet what I found raised concerns in me. Many of those vehicles had problems that began with the instrument cluster, but eventually led to the engine refusing to start. (an electronic instrument cluster, digital instrument panel or digital dash for short, is a set of instrumentation, including the speedometer, that is displayed with a digital readout rather than with the traditional analog gauges. Many refer to it simply as a digital speedometer.) http://www.instructables.com/id/Erratic-Instrument-Panel-on-GM-Cars/

Sounds like the water pump is cavitating . Replace water pump. Check coolant level also. Open the bleeder valve usually located on thermostat housing to remove air from system. close valve when coolant is present while filling. close radiator cap and top off recovery bottle to correct level. These engines are prone to overheating, do not let temp gauge get in the red.

The electronic brake control module (EBCM) automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.

Is the check engine light on? I'm sure changing the oil had nothing to do with how the vehicle is running now unless they didn't replace the oil drain plug or added enough oil.

If the antitheft light is on and the car won't start,turn the key to on position and wait for the antitheft light to flash or go out (can take up to 20 mins)then try and start the vehicle.This is the key relearn procedure when the ignition switch does not read/see the key chip correctly.

Could be lose connection on the back of the instrument cluster ,which means you would need to pull it out of the vehicle . Check pin fit to instrument cluster . for the B+ voltage suppy an ground connection's . You said autozone - Tried to have auto zone diagnose from inside the car, came up with no codes. That's in the PCM - engine computer . There scan tool will not communicate with the instrument cluster ,which is also a computer in it's self. Need a factory scan tool to check instrument cluster. Speedometer and/or Odometer Inaccurate Step Action Value(s) Yes No Important: A short to ground will cause an open fuse(s). Before performing this diagnostic procedure, inspect the fuse(s) for an open. 1 Did you perform the Instrument Cluster System Check? -- Go to Step 2 Go to Instrument Cluster System Check 2 Turn the ignition switch to the ON position. With the scan tool select Instrument Panel Cluster, Special Functions, Instrument Panel Cluster (IPC) gauges. Perform the Speed Gauge Sweep Test. Does the speedometer complete a full sweep when commanded? -- Go to Powertrain On Board Diagnostic (OBD) System Check in Engine Controls Go to Step 3 3 Replace the instrument cluster. Refer to Instrument Cluster Replacement . Did you complete the repair? -- Go to Instrument Cluster System Check -- With a scan tool select the instrument panel cluster, data display, gear status. Monitor the gear range status. Move the gear lever through each gear. Does the scan tool display the correct gear selected? Your best bet , take it to a qualified repair shop .

check the fuses such as cig lighter //acc and or harness to obd port for damage or short but usually blown fuse is problem

If you're fortunate, it's simply lit to tell you it's time to have any number of services done. Some check engine lights are synced to come on at certain intervals. If it's not that, then it could be one or more of too many problems to even guess at.

ok... the engine compartment is the entire opening under the hood...the coolant surge tank is located at the front, it is usually white plastic with a plastic cap with a warning not to open when hot. hope this helps.

metal on metal possible will need brake pads and rotors ---as to abs activaction hub goiging bad abs sensor going bad but if driving and the ice and snow and abs activate then thats normal and the sound is the worn brakes

Hi, try unhooking your Negative battery terminal and leaving it unhooked for about 5 minutes, then reconnect it. This should clear any fault codes that are stored in the computer. It's very possible that your BCM, ( Body Control Module) is failing. Take your car to a Mechanic that you trust... Hope this helps.

There is NO way you're gonna get through a smog check without fixing the problem. You can turn off the light, but that'll be an automatic fail. They can tell when you clear a code.

Best way ? take it an have a vacuum flush an fill .

Transmission fluid pump going bad . Have it check to know for sure .
