Extreme heat can cause warping and the cd will not evenly eject or exit the slot. the player may have to be removed and the cd physically extracted from the player. Delco players have a lot of plastic cogs, flywheels and gears in them that get old and crack or split. Hence, the player can no longer spit out the CD.

Key fobs have to be reprogrammed. something has knocked the coding off. Search the web for procedures to program fobs. It usually entails operating ignition a series of power lock sequences and the like. If that does not work you can take it to the dealer and they can recode it using the data from you cars computer, but that is extremely expensive.

I took my car into the dealership on friday 02-13-09 only to find out my steering column needs to be replaced the motor is shorting out for the power steering ~ certain models of malibu's 2005 yr if your vin falls between 5F100001 - 5F250216 call Chevrolet they have a Technical Service Bulletin # 07126 - SPECIAL COVERAGE ADJUSTMENT - LOSS OF POWER STEERING ASSIST - 7 yrs or 70,000 miles regardless of ownership - they will cover the cost of the repair ~ Chevrolet 1-800-630-2438 or
1-800-833-2438 - They saved me from having to pay out of pocket !!!

I would test both the tps and map sensors. map sensor is here: Testing Check the Manifold Absolute Pressure (MAP) sensor circuit as follows:Ignition OFF, disconnect the MAP harness connector at the MAP sensor.Ignition OFF, test for less than 5 ohms of resistance between the low reference circuit terminal 2 and ground.If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the ECM.Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal 1 and ground.If less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the ECM.If greater than the specified range, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the ECM.Verify the scan tool MAP Sensor parameter is less than 1 kPa.If greater than the specified range, test the signal circuit terminal 3 for a short to voltage. If the circuit tests normal, replace the ECM.Install a 3A fused jumper wire between the signal circuit terminal 3 and the 5-volt reference circuit terminal 1. Verify the scan tool MAP Sensor parameter is greater than 126 kPa.If less than the specified range, test the signal circuit terminal 3 for a short to ground or an open/high resistance. If the circuit tests normal, replace the ECM.If all circuits test normal, test or replace the MAP sensor. Check the Throttle Position (TP) sensor circuits as follows:Ignition OFF, disconnect the harness connector at the throttle body.Ignition OFF for 90 seconds, test for less than 5 ohms of resistance between the low reference circuit terminal C and ground.If greater than 5 ohms, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the ECM. Ignition ON, test for 4.8-5.2 volts between 5-volt reference circuit terminal E and ground.If less than 4.8 volts, test 5-volt reference circuit for a short to ground or an open / high resistance. If the circuit tests normal, replace the ECM.If greater than 5.2 volts, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the ECM. Verify the scan tool TP sensor 1 voltage is less than 0.1 volt.If greater than 0.1 volt, test the signal circuit terminal D for a short to voltage. If the circuit tests normal, replace the ECM. Verify the scan tool TP sensor 2 voltage is greater than 4.8 volts.If less than 4.8 volts, test the signal circuit for a short to ground. If the circuit tests normal, replace the ECM. Install a 3A fused jumper wire between the signal circuit terminal D and the 5-volt reference circuit terminal E of the TP sensor 1. Verify the TP sensor 1 voltage is greater than 4.8 volts.If less than 4.8 volts, test the TP sensor 1 signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the ECM. Install a 3A fused jumper wire between the signal circuit terminal F and the low reference circuit terminal C of the TP sensor 2. Verify that the TP sensor 2 voltage is less than 0.1 voltIf greater than 1.0 volt, test the TP sensor 2 signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the ECM. Ignition OFF for 90 seconds, disconnect the harness connector at the ECM.Test for less than 5 ohms of resistance on all TP sensor circuits between the following terminals:ECM C2 signal circuit terminal 65 to TP terminal DECM C2 signal circuit terminal 63 to TP terminal FECM C2 5-volt reference circuit terminal 3 to terminal E If greater than 5 ohms, repair the affected circuit for open/high resistance.Test for infinite resistance between TP sensor 1 signal circuit terminal D and TP sensor signal circuit terminal F.If less than infinite resistance, repair the short between TP sensor 1 signal circuit and TP sensor 2 signal circuit. If all circuits test normal, replace the throttle body. Fig. Throttle Actuator Control electrical connector Throttle Body Relearn Procedure NOTE Do NOT perform this procedure if DTCs are set. Start and idle the engine in PARK for 3 minutes.With a scan tool, monitor desired and actual RPM.The ECM will start to learn the new idle cells and Desired RPM should start to decrease.Ignition OFF for 60 seconds.Start and idle the engine in PARK for 3 minutes.After the 3 minute run time the engine should be idling normal. NOTE During the drive cycle the check engine light may come on with idle speed DTCs. If idle speed codes are set, clear codes so the ECM can continue to learn. If the engine idle speed has not been learned the vehicle will need to be driven at speeds above 70 km/h (44 mph) with several decelerations and extended idles. After the drive cycle, the engine should be idling normally. If the engine idle speed has not been learned, turn OFF the ignition for 60 seconds and repeat step 6.Once the engine speed has returned to normal, clear DTCs.

Please check your owners manual for the location of the 10 amp fuse for the radio. On some models you have to reset the security feature on the radio/CD player for it to work. The info below has been stated to work on a no go radio. I have not confirmed this procedure. Remove the lower fuse box cover, with the power off, removed the 10 Amp fuse for the "Radio." the fuse may be good. Fuses are diagrammed in the owner's manual. With the fuse removed, start the car, turn the car off, replace the fuse and turn the key to "ACC" to see if the radio was "Reset." Would the alarm cause the radio to malfunction? If your Anti Theft lock was activated check your owners manual under radio and check for a 4 number password. Sometimes it is taped to the upper part of the glove box. If you do not have the CODE you will need to take the vehicle to a dealership or a repair center. They use your vehicles vin number get the code.

can be a sign the cam or crank sensor is on its way out, can also be a dirty MAF sensor. cam sensor will make the engine run ruff, MAF will make engine ruff and not idle properly, Crank sensor if it fails it shuts engine down as it dont know were the engine is at on its cycle. air filter changed or replaced damage air filter will coat the maf with muck and it will need cleaning off the sensor, easy to do with MAF cleaner. sensors they can fail when they to hot for them to run anymore or to cold. the resistance in the sensor goes up and down in different temperatures. some time when it goes completely out of range the engine light comes on, but a failing one that is still in range makes the engine run out of order.

If that light comes on a fault code is set in the control module, you need a scanner hooked up to read that fault code.

Its not firing on all cylinders is all the h.t.lead and coil been checked ps take it back to the shop who done the work , you paid them so you want it right good luck colin

it could be the fan motor resistor, i would check the main fuse for the fan on the heater. if the fuse is ok then the resister is either gone or has become unplugged.

You are correct about the main blend door sticking friend. And it happens to cover the heater core part of the box under the dash on the passenger side. Look under the hood at the firewall and see where the hoses connect to the heater core. That's the position your looking for. Could also be just a tight bend in a vacuum line from the blend switch valve to the door itself. Everything to do with heat and A?C is vacuum actuated from a vacuum canister under the hood. A black round ball about 4 inches in diameter.

pressing again the pedal

messed up a brake line somewhere under the car, check to make sure you have brake fluid

had very similar problems with a Hyundai coupe , turned out to be the central locking control mechanism , this is usually the drivers door lock unit inside drivers door , this controls the locking system and so also interior lights as if having used remote etc,hope this helps

VEHICLE RELAYS Operation Diagnosis Find which side of the relay has problem . Control or load !

Probably the catalytic converter also.

What aftermarket stuff have you had installed ? any ? Radio etc..... What alarm does not work ? Content theft ? How is pass lock disabled ? AC temperature ????? Do you own a factory or professional grade scan tool ? Will all the modules on the vehicle communicate with the scan tool ? GM had a problem with instrument clusters ,step motors ! That could be your fuel gauge problem , plus the solder they used , have you heard of silver migration .Just guessing as to a problem never fixed anything , that's all anyone on here would be doing , guessing . Testing electrical circuits ,power an grounds . Loaded circuit voltage testing, voltage drop testing etc.. Do you know how to do automotive electrical testing , how to read an use a wiring diagram to pin point test areas . Do you know what C.A.N. is controller area network , a serial data ,communication network for the modules on the vehicle . How to Diagnose Controller Area Network CAN How to repair GM Instrument Cluster Speedometer Gauge Stepper Electric Testing Techniques You Need to Know Free wiring diagrams here http://www.bbbind.com/free_tsb.html You have no idea of the complexity of the electronics on your vehicle , The BCM , radio , HVAC , Instrument cluster , ABS , PCM/ECM , SRS , an others are all hooked to to the data bus ,or network , all it takes is one module to act up to bring the whole system down , causing no start problems ! Hooking up a scan tool is the first step .
