Brake light and the trac off light

The light comes on and goes off when you start the engine as a test. If the light comes back on, there is a problem and you need to get the body computer scanned for trouble codes. The traction control uses the engine and ABS braking system to work.

Try to change a new brake booster may help. http://www.fiverhope.com/

Are you talking about the courtesy lights ?
You may have a door jamb switch stuck open.

hey man sorry to tell you this but u will need a cat bank 2 its easy to take out it should only be 5 12mm nuts on the top and 2 14mm bolts on the bottom and some that r holding on to the trans.

check the wiring to the rear sockets, including grounds then work your way forward, check the brake light switch then the signal light switch which i figure is bad but no sense replacing till you know everything else is good

Look up above your brake pedal and you should see a switch that is connected to it. This switch controls your brakes and in some vehicles, is tied in to the safety system. Change this and see if your van goes into gear ($10 part)

is it getting spark to all the spark plugs? fuel?

You have a bad hub bearing. 100% garunteed. The light is on because the bearing is so bad it hit the sensor for the abs & traction control , breaking it. So you're gonna need a bearing, a sensor,probably new brake pads,any seals{probably one} & a shop that can do it. The bearing is pressed in & needs to be pressed out. Heating & beating is not a good idea.

You may have a bad abs controller. You need to get the code for the abs light from a shop or auto parts store.

The problem is probably the wheel hub bearings and it is more that likely the front. I had the same problem a few weeks on my 00 grand am gt. Connected the car to the tester it gave me a code for left front wheel bearing. I replace both wheel bearings because i figured what the hell they both have the same amount of miles on them. Taaadaaa no more lights!!! Hope this solves your problem.
