Here's a video showing you how to remove battery. Battery Replacement 2001 2005 Pontiac Aztek 2003 Pontiac Aztek 3 4L V6

Unless you have a computer, like a GM tech II your will have to take it to someone like a GM dealer to unlock it.

limp home feature be disabled ????? It's not a feature as you put it . Vehicle has a problem , have the DTC'S check have the problem fixed , then it won't be in limp home mode , Probably something wrong with the transmission

Try turning the stop sensor clockwise a quarter turn. If you follow the brake pedal up you will see the two with plungers the brake hits when you depress the brake.

Inside the transmission . (334) Torque Converter Clutch (TCC) Pulse Width Modulation (PWM) Solenoid Valve (ME7 or MN5

1. Disconnect battery.
2.Remove the bolts from the two dogbone motor mounts located at top of motor front of car.
3.Disconnect the upper radiator supports (this provides a little extra tilting room).
4. Use a ratcheting strap to jack/tilt the engine forward. Attach one end to an anchor point toward the rear of the engine and the other to the frame above the radiator.
5. Ratchet/tilt the motor as far as possible.
6. Remove serpentine belt.
7.Tie a rope or tether of some sort to the alternator.
8. Remove bolts from alternator (if i remember correctly there are 3).
9. Using the rope lower the alternator down behind the motor so you can remove it from under the car.

You will the reverse procedure for installing a new one. Other people will suggest removing the windshield wiper transmission or resevoir. But i prefer to remove as few parts as possible. This same "tilting" method you will use to change your spark plugs/wires. So use high quality plugs /wires at least for the 3 rear ones or you will be repeating this headache soon. Trust me.

The fuel tank must come down. Only way

What light is lit ? When light's are lit on the instrument cluster , air bag , check engine , ABS etc... usually means there is a problem with that system , an there are DTC'S - diagnostic trouble codes stored in that systems control module . You need to take it to a qualified repair shop an have diagnostics done to see what the problem is .

Left. Facing the head of the bleeder valve

I don't think it's the radiator cap. I'd just replace the thermostat and see if that resolves the problem. you can also remove the thermostat just to see if it still runs hot.

if it runs hot with a new thermostat or without one, then have the engine professionally flushed. this is a pressurized flush.

without more information on mileage or vehicle, thats the best place to start on this issue. If you need further help, reach me via phone at https://www.6ya.com/expert/ray_6d6dc1dfa6f18dc1

Your best bet would be to take your vehicle to a ASE certified professional . You do not have the tools to diagnose this or the information. DTC P0753 The 1-2 shift solenoid (1-2 SS) valve controls transmission fluid pressure acting on the 1-2 shift valves to position the valves for the appropriate gear. The 1-2 SS valve is a normally-open exhaust valve located on the control valve body. A fused circuit supplies ignition voltage to the 1-2 SS valve. The PCM commands the solenoid ON or OFF by switching the ground path. When the 1-2 SS valve is commanded ON, the PCM senses low voltage. When the 1-2 SS valve is commanded OFF, the PCM senses high voltage. Refer to Shift Solenoid Valve State and Gear Ratio . If the PCM detects a continuous open, short to ground or short to power in the 1-2 SS valve circuit, then DTC P0753 sets. DTC P0753 is a type B DTC. DTC P0753 sets when one of the following conditions occurs for 5 seconds: Condition 1 The PCM commands the solenoid ON and voltage feedback remains high, B+. Condition 2 The PCM commands the solenoid OFF, and the voltage feedback remains low, 0 volts. DTC P0758 The 2-3 shift solenoid (2-3 SS) valve controls transmission fluid pressure acting on the 1-2 and 2-3 shift valves to position the valves for the appropriate gear. The 2-3 SS valve is a normally-open exhaust valve located on the control valve body. A fused circuit supplies ignition voltage to the 2-3 SS valve. The PCM commands the solenoid ON or OFF by switching the ground path. When the 2-3 SS valve is commanded ON, the PCM senses low voltage. When the 2-3 SS valve is commanded OFF, the PCM senses high voltage. Refer to Shift Solenoid Valve State and Gear Ratio . If the PCM detects a continuous open, short to ground or short to power in the 2-3 SS valve circuit, then DTC P0758 sets. DTC P0758 is a type A DTC. Conditions for Setting the DTC DTC P0758 sets when one of the following conditions occurs for 5 seconds: Condition 1 The PCM commands the solenoid ON and the voltage feedback remains high, B+. Condition 2 The PCM commands the solenoid OFF and the voltage feedback remains low, 0 volts. What's this p91860 , no such code .

There is no safety shut off switch .First off you say it still won't crank , I'm assuming you mean it won't start an run . If you turn the key to the start position an the engine spins ,that is referred to as the engine cranks . You have a no crank - no start or engine cranks - no start . A fuel pump would have nothing to do with a no - crank -no start problem . If the engine is cranking an not starting check for spark at spark plugs . Is there a security light lit on the instrument cluster ? a anti-theft system problem will cause a crank - no start problem . A short on the five volt reference circuit will cause a crank - no start . A shorted map sensor , shorted TP - throttle position sensor

I think those things are computer controlled (ECM) but you can use a scanner to command and check, if it is working.

TO WHAT?

Is there a door ajar light on? How about a seatbelt light on? These will cause the chime to sound. Possible door switch causing issue. You can unplug the chime module from under the dash. Listen for the noise to locate it and unplug it.
