2013 ford f-150 the inst. panel says right rear doir open when it isn't. Lights stay on. How can i fix this problem?

Have body control system checked for DTC'S - diagnostic trouble codes . On newer vehicles like yous ,everything set's a code now a days . Probably a electrical circuit problem or door ajar switch . Looking at data inputs to SJB - smart junction box , fords BCM - body electronics control module , on a scan tool will show what the problem is . The dealer I work at charge's $ 23.00 to hook - up factory scan tool . Or you could take a chance and change the door ajar switch . Would need to take inside door panel off to get at it .

My 2001chevy blazer security light came on while driving went back off after few minutes now car stalls and then want start up until hours later codes show o2sensor misfires tps and security alarm ???

What type scan tool are you using ? or are you using a code reader ? The SECRUITY -anti-theft system codes are stored in the BCM not the PCM !You need a factory scan tool or a professional grade one to check Body Control Module DTC'S -diagnostic trouble codes !
The theft deterrent system has been incorporated into the body control module (BCM). The theft deterrent is provided in order to prevent the vehicle operation if the correct key is not used in order to start the vehicle. The ignition key turns the lock cylinder. The cylinder rotation produces an analog voltage code in the Passlock?"¢ sensor. This voltage code is received by the BCM. The BCM compares the voltage code to the previously learned voltage code. If the codes match, a class 2 message is sent from the BCM to the powertrain control module (PCM)/vehicle control module (VCM). The message enables the fuel injectors.

What will happen if I take my baffels out of my 2013 fat bob dyna? Will it hurt the motor in any way? Just wanna make people in cars hear me coming. Its to quiet stock.

It'll probably lean out the air/fuel mixture and over time, yes, it can hurt the motor!

With fuel injection, you'll need to either take it to the dealer so they can plug it in to their computers and reprogram the injection, or buy a "piggy-back" unit that plugs in, to "fool" the system to run richer.

The power door locks, windows, interior lights, and radio all stopped working on my 2002 Rendezvous. One morning my key fob would not unlock the car and so I did it manually and the security light stayed...

What kind of place did the diagnostics ? Auto part stores ? The BCM - body control module . Takes a proessional or factory scan tool to pull codes from this module .
The body control module (BCM) is capable of accomplishing multiple body control functions. Components directly connected to the BCM are controlled by the BCM outputs. The BCM can control its outputs based on input information it obtains from sensors and switches that are directly connected to the BCM, or by receiving information from other vehicle systems connected to the class 2 serial data link. The BCM evaluates this information and controls certain body systems by commanding an output on or off.
The BCM is also capable of commanding other vehicle systems to control functions that are not directly wired to and/or controlled by the BCM. The BCM accomplishes this task by sending specific messages on the class 2 serial data link. The vehicle system capable of performing such function will respond to the BCM message.
The BCM controls/monitors the following functions:
• Audible warnings
• Indicators control
• Interior lighting
• Exterior lighting
• Power/automatic door locks
• Keyless entry
• Content theft deterrent
• Personalization
• Serial Power Modes
• Electrical Power Management

Hooking up a Tech 2 factory scan tool to see if the BCM will communicate would be the first step in diagnosing this problem ,also checking codes an to see if the scan tool can bidirectionally control the lock's window's etc.. I would suggest a buick dealer !
