2006 ford sport trac will not shift out of park


Look under the dash, on the brake pedal arm. There are one or two switches that activate brake lights and/or shift unlock. Check for loose mounting nut or a missing rubber nubber. Is the brake pedal coming all the way back up? Look on the floor for something not usually found there. These switches are adjustable and it may be as simple as adjusting them. Have a helper look for brake lights on and shift lever unlocked while you push and release the switches with your finger. Depress the brake pedal to get it out of the way. Remember to set the park brake first. Could just be a bad switch or loose connector. Check fuses and the bulbs. Is shifter fully in Park? Also try jiggling the turn signal lever.

Why does the silhouette make the hummin nooise when the abs/tcs light is on


The humming noise is probably caused by a bad bearing hub assembly which also caused the abs and tcs light to come on. Does this only make the noise when the lights are on and vehicle is not moving or just when vehicle is moving?

Brake lights come on and stay on when started.Recently replaced left brake light bulb


It sounds like the brake switch on the brake pedal arm is stuck its like a push button type switch when you press the brake pedal down it pushes the button in on the switch which makes the brake lights come on,when you take your foot off the brake pedal the button is supposed to come back out if it doesn't the brake lights will stay on.

Hummin sound when turning to the left no trac light comes on and the brake pedal pushes back


You have a partially broken wiring harness to one of the front wheel speed sensors. As the wheels turn back and forth they tend to fatigue the harness and cause an intermittent brake in the wire , this makes the computer think that you have lost traction and triggers the ABS/Traction control system. You'll need to have the computer scanned for abs codes and figure out which sensor is showing as bad. If the problem is not bad enough yet, the code may not have stored. Either way, you will have to get an ohmmeter and carefully test the resistance of the speed sensor harnesses to find out where it is broken. An alternative is to just replace the wiring between the sensor and where it fastens to the frame. Any place that the wire has to move when the wheels are being steered is suspect.

ABS light goes on and off


Sounds like you have loose brake pad linings.
The traction control measures rotational speed between each rear wheel. If your pad lining momentarily causes one wheel to hesitate your trac control will flash. As the ABS detects braking without the brake pedal being pushed, it will flash.
Check your emergency brake pads. They can fall apart inside the drum/rotor combo on the rear. That is where your sensor is for the ABS.

2004 grand am weird noise


Have you noticed if the noise changes while doing a swerve to the left or right ? If so , it is likely a wheel bearing & will require replacement of the entire hub .

2003 Chevy Impala Service Traction Sytem show on Dash


I can't answer the question about the gas fumes, but I had the same problem last year with the "Service Traction Sysytem" message and the Trac and ABS lights coming on in my Impala. Mine turned out to be because of a bad wheel bearing, that was causing the ABS and traction system not to work. I'm not sure if you've experienced this, but another thing that would happen with mine was that I would go to brake and have a hard time depressing the brake pedal, almost like it was pushing back. That is the point when the Trac and ABS lights came on.
