Audible Warnings Description and Operation
The audible warnings alert the driver of a system concern or a critical vehicle condition. The instrument panel cluster (IPC) generates audible warnings through an internal acoustic speaker. The IPC receives audible warning requests via the serial data circuit. If the IPC receives multiple audible warning requests, the warning with the highest priority sounds first. The following lists the audible warning priority and the pulse rate:
Fast rate chime (200 pulses per minute)
Medium rate chime (150 pulses per minute)
Slow rate chime (50 pulses per minute)
Single chime
Door Ajar Warning
The IPC activates the door ajar audible warning as requested by the body control module (BCM). The BCM sends a serial data message to the IPC indicating the chime frequency and duration. The door ajar warning sounds and the appropriate DOOR AJAR indicator illuminates in the driver information center (DIC) when the following occurs:
• The body control module (BCM) determines that a door, driver door, passenger door. The IPC receives a serial data message from the BCM indicating the door ajar status.
• The vehicle is not in park. The IPC receives a serial data message from the BCM indicating the gear position.
• The vehicle speed is greater than 8.05 km/h (5 MPH). The IPC uses the vehicle speed information from the ECM to calculate the vehicle speed.

dont need to remove bcm fuse to program a fob the bcm needs to be active to program standard for - unless you have remote start then needs to be flashed to your vin by dealer or an authorized shop this link is for the lock unlock standard fob https://itstillruns.com/program-colorado-key-fob-7191242.html
you can get guide from many sites.. i know few
error codes/ fault codes, wiring diagrams, schematic diagrams, torque specs, engine info, switches functioning, assemble, disassembly, complete refurbish, repair, installation every single thing is covered
within seconds u can get the access and it's totally illustrative complete
This diagram is part of wiper circuit. Couldn't get everything in one picture. There could be other issues?
bbbind.com should have wiring diagrams for your wipers. You can look at the whole thing.
My guess is it's a timing chain problem, especially if it has a lot of miles (140K +) That model engine is notorious for bad timing chains.
I have the same engine and basically have had the same problem. Have a friend with one ('07) - same problem.
It's a pretty expensive problem to repair. Labor (by the Flat-Rate manual) is in the 14hr range plus parts. Used engines with low mileage (60K) are rare and around $2K when you find one.
If the ABS light comes on, you've got trouble codes stored. Get the codes read. This is usually caused by bad wheel speed sensor, rust on the tone ring or metallic crud on the sensor
You need to have the system tested. It sounds like it is either low on refrigerant or there is a blockage in the system causing too much pressure and the system being disabled by the high pressure switch.
Seems like the fuel line looses its fuel or something. ????? That would cause a no start or hard start problem . Your best bet , have it diagnosed by a repair shop . That is unless you want 20 different answers on here . Are you willing to replace parts your vehicle doesn't need . Testing is the only way find the problem , not guessing , that's all you'll get on here . Hooking up a professional type scan tool an checking sensor data parameters to see what is a miss . Doing fuel pressure testing ,hooking up a pressure gauge .
007 Idle Speed Problems Scan Data for Idle
It may seam extremely complex this problem however its likely vary simple.What you need to do is fine out what works and what dose not . Dose the keyless work on other doors the battery is G or NG. You also mention the remote starter stopped working and D and P position no longer works correctly with the controls /switches in the drivers side door only' not the other doors ..
The control panel for the locks and window switches are on the arm rest drivers door it tends to get wet rain snow window open over time bad connections /switch contact and that is the point you need to look at first . Get some electrical contact cleaner spray into the switches not to much spillage use a tube or it may damage trim materials .
Then use the controls back and forth if you see any improvement of function starts /then stops any change you found the problem .Its in the door.
So , the power door locks won't lock or unlock with switches inside the vehicle or with the keyless entry remote fob.??? Is this correct ????
Do you know what a BCM - body control module is ? Do you know what diagnostic trouble codes are ? If not your best bet would be to take your vehicle to a GM dealer or someother qualified repair shop.
DTC B3142 or B3143
The body control module (BCM) provides an output to the driver switch assembly through the door unlock control circuit for controlling automatic door unlock, anti-lockout, and keyless entry unlock functions.
DTC B3152 or B3153
It could be the driver door master switch , could have broken wires inside the rubber boot from the body to the door . Do the power windows work ?
The keyless entry system has the following main components:
• The transmitters
• The body control module (BCM)
When you press a button on a transmitter, the transmitter sends a signal to the BCM. The BCM interprets the signal and activates the requested function.
How did you do this ,,checked and made sure locks and remote programmed,they were,but still do not work ?????
Need a scan tool to program
Important: All key fobs must be programmed each time any one fob is programmed. The scan tool must stay connected until all of the transmitters are programmed.
Install a scan tool and navigate to the BCM Module Setup menu.
Select Program Key Fobs.
Follow the scan tool on-screen directions.
When the programming operations have completed, operate the transmitter functions to verify correct system operation.
