The chimes an turn signal noise come out driver door speaker . Both front speakers not working could be a blown circuit fuse inside the radio or just blown front speaker channel . Your best bet , take it to a GM dealer or someother qualified repair shop . You have no idea of the complexity of this . The radio can set DTC'S - diagnostic trouble codes , believe it or not ! DTC B1025, B1035, B1045, or B1055 DTC B1025 01: Audio Output 1 Left Front Circuit Short to Battery DTC B1025 02: Audio Output 1 Left Front Circuit Short to Ground DTC B1035 01: Audio Output 2 Right Front Circuit Short to Battery DTC B1035 02: Audio Output 2 Right Front Circuit Short to Ground DTC B1045 01: Audio Output 3 Left Rear Circuit Short to Battery DTC B1045 02: Audio Output 3 Left Rear Circuit Short to Ground DTC B1055 01: Audio Output 4 Right Rear Circuit Short to Battery DTC B1055 02: Audio Output 4 Right Rear Circuit Short to Ground Each of the audio output channel circuits (+) and (-), at the radio and audio amplifier have a DC bias voltage that is one half of the battery voltage. When using a DMM, each of the audio output channel circuits will measure approximately 6.5V DC. The audio being played on the system is produced by a varying AC voltage that is centered around the DC bias voltage on the same circuit. The AC voltage is what causes the speaker cone to move and produce sound. This voltage will vary depending on what type of audio is being listened to, talk or music, and type of music, as well as the volume setting of the system. Low volume and talk settings will measure around 1V AC and less, where constant music may measure 3V AC and slightly higher. DTC B1287 01: Amplifier Control Signal Circuit Short to Battery DTC B1287 02: Amplifier Control Signal Circuit Short to Ground DTC B1287 04: Amplifier Control Signal Circuit Open The radio provides a remote amplifier mute output circuit to control overall muting of the remote amplifier. The amplifier receives pulse width modulated (PWM) signals on the control circuit at varying duty cycle percentages for controlling muted and unmuted functions of the amplifier. Circuitry internal to the radio monitors the remote amplifier mute circuit for faults and sets the appropriate DTC when faults are detected.

check the engine OBD2 codes. you may have bad crank shaft or cam shaft sensors. replace them all ....

The trunk ajar switch is probably bad ,this is a signal to the BCM - body control module . The control module sends a message to DIC - driver info. center telling it to display this massage. Stalling problem could be as simple as a dirty throttle plate . Your vehicle has electronic throttle control ,computer controlled ! What kind of starting problems ? Long crank time ,no crank etc... Should explain these a little . No crank -when you turn the key nothing happens . Long crank time - you turn the key to start an the engine spins & spins for a long time before the engine starts .

You more than likely have a shorted wiring harness somewhere in the wiring to the transmission shift solenoids, this is a problem that is difficult for a professional to track down. Pull the harness loose and look at it, examine for wires rubbed through. You can try unplugging the harness from the transmission and see if the short goes away, if it does the shift solenoids are the problem.

on the upper intake manifold.

GM actually wants you to take it to a shop or the dealer. They stopped using a dipstick. Here is the method - - Start the engine and allow the engine to idle until the transmission fluid temperature has reached at least 105degF. Depress the brakepedal and move the shift lever through the gear ranges, pausing a few seconds in each range. Return the shift lever to the PARK range. Remove the fluid vent cap. (red capon drivers side top of trans) Raise the vehicle on a hoist(or support on jackstands) . The vehicle must be level, with the engine running and the shift lever in the PARK range. Remove the transmission oil level control plug(its a small usually 10mmhex bolt on the right/passenger side of trans, below and in front of the right hand axle.) Check the fluid level. The fluid level should be even with the bottom of the threaded plug hole. Add DEXRON®IIIautomatic transmission fluid in increments of 0.5 L (0.5 qt) until the fluid drains from the plug hole.

Does it jerk when you release the clutch in neutral? Is so, what gear? try them all before responding.

Most cars have one

Look on the transmission for plug in connectors. It sounds like one of them lost connection. I would unplug them and re-seat them. It is always possible that they are disconnected on the inside of trans too. By the way these are both transmission codes.
