Try takeing the fuse under the hood marked ABS 60 amp to see if that helps if so you will need a new abs control module.

Abslight stays on. How to fix? This is a2007trailblazer?


First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

I have a 2005 Trailblazer that dies out when you come to a stop. It starts back up with no problem


The alternator wouldn't have anything to do with either of the problems your having ! The key getting stuck in the ignition could be a problem developing with the lock cylinder . Can you turn the key to the off position an then it won't come out ? Or it won't turn to the off position an then not come out ? There are safety devices in place that won't let the key come out if not in gear an foot on the brake pedal etc... electronic an they do fail . Electronic Park Lock (EPL)/Ignition Lock Cylinder Control Actuator:Linear Shift Assembly: If the vehicle is equipped with a column mounted gear shift, it has a linear shift assembly on the steering column. The linear shift assembly has a cable that runs from the linear shift assembly to the ignition lock cylinder case. The purpose of this cable is to prevent the ignition key from being turned to the OFF position when the transmission is in gear and the vehicle may still be moving. The linear shift assembly cable contains a pin that is spring loaded to mechanically prevent the ignition key cylinder from being turned to the lock position when the vehicle transmission is not in the PARK position. If vehicle power is lost, and/or the transmission is not in the PARK position the operator will not be able to turn the ignition key to the lock position and will not be able to remove the ignition key from the column.

Now for the stall at stops , Your vehicle has Throttle Actuator Control (TAC) System ,electronic throttle control or drive by wire ! It is electronical controlled .
There are sensors in the gas pedal an on the throttle body ,they are connected to the PCM/ECM - engine computer with wiring ! There is a DC electric motor on the throttle body , this is what opens the throttle plate . Throttle plates do become dirty with varnish an stuff that can cause idle problems ! There are videos on youtube showing how to clean a throttle plate . How to Clean Throttle Body 2007 Chevy Trailblazer

Brakes on my 05 trailblazer locked up while driving and the vehicle won't move.


ALL brakes locked up, or just rear? Rear could mean differential is locked up...Sounds more likely while driving it, as cars now have a front or rear valve so all brakes are not lost at one time..

Front brakes locking up on 2007 Chevrolet equinox


There are many possible factors including incorrect parts, defective rotor - pads - actuator, improperly bled front brake line, improper maintenance practice during last service. Best to take the vehicle to a qualified mechanic as soon as possible for your and others safety. Tow if you feel it is unsafe to drive that distance. Best of luck.

The lock button on the gearshift will not unlock on my 2002 Chevy TrailBlazer. I read online that I should press an orange lever under the center console but when I looked in there I found the lever on...


Since the lever is obviously no help, try this:

BRAKE LIGHTS AND SHIFT LOCK
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?

When I start engine then depress brake pedal and try to depress shift lever button I can't get it ou of park. This happens 6 times out of 10.


In the area of the shifter (in the center console), there is a shift lock solenoid that is activated by the brake switch. This solenoid prevents shifting out of the Park position unless the brake pedal is depressed. Your problem could be either the brake switch or the solenoid. I would try replacing the switch first.

We have a 2007 Entourage and you cannot lock it with the car running. We installed a remote starter and it will not lock the doors when it is remotely started. Can this feature be disabled?


i think that this is to prevent you from locking your keys in the car with the engine running.
Some remote starters have a feature that when the car is running (and in park) you can hit the remote start button twice for one second each - then you can take the key out of the ignition and still have the car running.
At this point....if you would hit the 'lock' button on your door the doors would immediately unlock. However, if you get out of the car and close the door leaving it unlocked and then you hit the 'lock' on your original car remote the doors will lock and stay locked. So now the car is running the doors are locked and you have the keys in your hands. Then you can run into the store or house real quick with your car locked.
Once you come back, you hit 'unlock' on the original car remote. the doors will unlock - you can get it - and then before hitting the brake put the key in the ignition and turn it (dont crank it) as if you had when originally using the remote starter.
Maybe this will work for you.....
