Press your lock button a second time and the headlight should go off. Often the dealership can reprogram to change things like that.

It needs compression, fuel and spark to run. You need to hook up a OBD2 and to the data link port under the dash, at the driver leg area. It pulls up a code and can guide you. Did you see white smoke before it stopped running? I am asking because that year and model is bad about blowing head gaskets.

do the power windows keep working too. . , Retained Accessory Power (RAP) . Retained accessory power (RAP) is a standard feature. RAP allows the radio, power windows, and if equipped, power sunroof and cellular telephone to operate for approximately 10 minutes after the ignition switch has been turned to OFF, or until a passenger compartment door is opened. The dash integration module (DIM) monitors and determines the ignition switch status (OFF, ACCESSORY, etc.). When the DIM determines that the ignition switch has been turned to the OFF position, the DIM sends a class 2 serial data message to the radio, drivers door module (DDM), rear integration module (RIM) and cellular telephone module (if equipped) in order to enable the RAP. After approximately 10 minutes the DIM sends another class 2 serial data message in order to disable the RAP. The DIM receives door status (OPEN, CLOSED) from the DDM by a class 2 serial data line message. When the DIM determines that a passenger compartment door has been opened, the DIM sends out a class 2 serial data message in order to disable the RAP, regardless of the elapsed time. 2000 Buick LeSabre ' LeSabre (VIN H) Service Manual ' Body and Accessories ' Retained Accessory Power ' Diagnostic Information and Procedures ' Document ID: 475077 -------------------------------------------------------------------------------- Retained Accessory Power (RAP) On After Timeout Step Action Value(s) Yes No 1 Did you perform the Retained Accessory Power (RAP) Diagnostic System Check? -- YES - Go to Step 2 NO - Go to Diagnostic System Check - Retained Accessory Power 2 Install a scan tool.

Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? -- YES - Go to Step 13 NO - Go to Step 9 9 Inspect for poor connections/terminal tension at the RAP relay. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? -- YES - Go to Step 13 NO - Go to Step 11 10 Inspect for poor connections/terminal tension at the harness connector of the RIM.

Did you correct the condition? -- System OK Go to Step 1 Without testing using the above factory diagnostic test proceduces , i would probably guess the rap relay has stuck contacts inside .

That can be a tough one to diagnose. I suspect they are not the only items in the car not immediately getting power, which suggests an intermittent problem with a master fuse or relay. If I were you, I would start by getting ahold of the circuit diagrams for the car (try Alldatadiy.com) and trace back the circuits from the brake and dashboard lights to where they reach a common fuse or relay and check those.

Go to www.car-part.com it has a built in Hollander interchange and will bring up all available interchanes.

Is it the volume knob or the light that won't work? If the light, there is not much you can do as it is not user serviceable. A local Delco dealer may be able to fix it. Same with the knob ...

If I remember correctly, 27mm

lower rear of engine near the transmission front side of vehicle . The engine sits transverse ,driver side front . Jack it up an look under the engine .

Try starting it in neutral. It may not be completely in park. Most 2000 lesabre cars have a safety feature, where after you turn the ignition on. You will hear a double beep noise and immediately try to start the engine. If not that, a fuse or starter relay. The relay will be under the hood. If that doesn't work you must have a bad connection from the ignition to the starter.

Does it have manual or automatic climate control . Do you know ? It's probably the blower motor control processor . electronically controlled . Your vehicle is the same as this GMC GMC Yukon HVAC Blower Motor Won Turn On

I think you could use this manual method instead.. My nephew used it to repair my car and it's perfectly fine now. Here's the website he bought it from. www.reliable-store.com

At www.reliable-store.com get complete guide on whether to repair or not, service it, and how to repair etc, along with wiring diagrams, electrical diagrams, torque specs, error codes, everything.

Very common. Bad wheel speed sensor. Read this http://ricksfreeautorepairadvice.com/abs-light-on-traction-control-off-gm-products/ ABS light on Traction Control Off GM products Ricks Free Auto Repair Advice

Could be a bad coil, bad spark plug, bad fuel injector, however one cylinder will not cause a no-start condition. Plug the wire back in and see if it will start.

Have it scanned looking for diagnostic codes. Sounds like you could have a crankshaft or camshaft sensor problem, which will be a simple fix.

bad connection to an abs sensor or a failing sensor.

Check the level switch at the back of the car - this turns the compressor on and off as the ride height changes. It may have come loose, is stuck or faulty.

the problem is probably caused by wheel bearing leads (the wires that plug into) they often wear out I had the same problem once u find out witch side try cleaning the plugs wiping clean free the dirt , salt ,ect but on one side I just bypass the plug ran jumper wires that solve the problem sometime the computer will reset it self sometime you have to take posative cable off wait 5 mins reconnect this will reset everything

The first thing the dealer would do is diagnostic's . Would not guess and just replace the BCM . Hooking up the factory Tech 2 scan tool an checking for DTC'S - diagnostic trouble codes , input data to the BCM etc. (I have reason to believe the BCM in my 2000 LeSabre is bad ???? )you have no clue ! The BCM has nothing to do with gauges , insturment cluster ! Beside's you still would need to take it to the dealer because it would need to be programmed . Leave this to a qualified repair shop . Plus the dash doesn't need to be taken apart to replace the BCM . Your vehicle actually has three modules for the body control system . The body control system consists of 3 modules: • The dash integration module (DIM) • The instrument panel module (IPM) • The rear integration module (RIM) You have no idea what your messing with . Your best bet ,take it to a qualified repair shop ,and that doesn't always mean you need to take it to the dealer . Each of the 3 body control modules integrate a number of functional systems under the control of a single module. Each of the modules is connected to the Class 2 serial data line. Many control signals are implemented by Class 2 messages. Important: The air bag indicator light may remain ON after the DIM module is replaced, and during the programming procedure for the DIM, until after the procedure is completed and the ignition key is cycled OFF and ON . • Before replacement, record the personalization settings to transfer to the new module (if they are available). • After replacement of the DIM, perform the following procedure. • In order to reprogram the DIM, perform the following procedure. Using a scan tool, preform the New VIN Procedure. Perform the Setup SDM Serial Number in DIM Procedure. Using the scan tool, set the Point of Sale in the DIM module to the correct country. Using the scan tool, configure the RPO option configuration. Perform the vehicle personalization in order to reset the owner's desired personalization settings. Refer to Instrument Cluster, Gauges and Console. Plus power door locks and windows are controlled by door module system , not body control system .The vehicle is equipped with power door locks. Each lock actuator is powered and controlled by the door module mounted in the individual door. The driver door module (DDM) is the master control for the door lock system but the rear integration module (RIM) contains the program that determines when the lock functions are permitted. Mess with the wrong stuff an you will render your vehicle useless cost to much to fix.
