Nothing, It doesn't work like that, when your brake switch is mounted , correctly , your pedal has a bracket on it that pushes the switch plunger in so brake lights are off. when you push brake pedal in, to stop vehicle, the switch plunger (spring loaded) comes out to turn brake lights ON ! get it ? when you release pedal it pushes plunger in, to turn lights OFF !

SOURCE: when i put on my brakes the engine stutters and the break lights

Sounds like you have 2 problems here.?

The engine stuttering sounds more likely to be an air leak on your brake servo system, weakening the mixture, and this will give you a lumpy tick over.

As for the stop lights, No 1 check its not the fuse.
You need to confirm you are getting a live feed to the brake switch with a 12v test light.
If OK, bridge this connection and recheck your feeds at the stop light bulbs.

Good Luck

These particular year models have a bad habit of the circuit board going out on them one at a time. I would by a new one from the parts house and replace it not a very expensive item.

SOURCE: tail light problem

carefuly test the socket that the light plugs into with a test light. I have seen alot of the newer pickups etc. that have the push in style lights have bad boards. cost like 19.00 at orielys. on the back of your tail lights when you take them off of the rig. do you have to unplug a wiring harness and take 2 screws out? and pull the black plastic peice out and the lights push in. that is the board i am talking about replacing. use the test light to check the plugend if it works that will tell you.

SOURCE: drivers side tail light lighting up at night when

You probably already know this, however the GMC 2002 Yukon Denali uses the Wagner 3157 (or equivalent) dual element bulb. The running light uses one element whereas the brake & blinker share the other element that burns brighter.

Check to ensure the correct bulbs are being used. Then check all wire harness connections. Since the blinkers function, then it sounds like the connections are good.

It really sounds like there is a bulb issue, so check that first, then let us know the results.

2001 maxima break lights remain on when off

There is a break light on off switch which is connected to the break pedal as you push the pedal the break light is on and when you release the pedal light goes off just look along side the pedal upwards there is a small connector swich just check the small pin type switch as it is in the refrigerator doors try by pushing it in gently to check if it is jammed or the other reason could be that the break pedal remains slight pushed inside from its orignal position to keep the switch on for this check the pedal springs amd lubricate them

This first link is specific to your 1st Generation's a great forum and hope you get your answers there
In my 2002 Honda Odyssey, the high brake light is accessed by removing a small triangular red piece from the right side of the cover. This piece often breaks but I was successful by soaking the area with STP silicone spray, waiting 15 minutes and then prying the piece up in the slot on the left side with a miniature flat bladed screwdriver. You then remove the underlying screw amd remove the housing. Twist the bulb holder out and remove the bulb by pulling straight out. Push the new bulb in - I usually hold it in a paper towel because by this time my hands are dirty. Twist the bulb holder back in. Push the housing back in starting on the left side. Replace the screw. Put in the triangular piece starting with the right side clip. I then pry the housing open with my screwdriver very carefully to fit the left clip in. If you break the piece it's under $10 at the Honda dealer. The piece is not well designed but you can make it work if you're patient.

Also, be sure you purchase the replacement light bulb lamp first before you tear everything apart. See sources and related links below for more light bulb information.

Clutch pedal box has snapped off its mounting on vw polo

1-disconnect battery. 2- remove all lower dash plastic panels. 3- disconnect all plugs on steering coloumn. 4- remove shear bolts on steering coloumn, easy with a long 8" sharp chisel (get 2 x new shear bolts £0.50p each). 5-loosen & remove bolt at steering rack in drivers footwell, mark position of spline before removing this makes it east to refit (tipex). 6- pull steering coloumn out towards you & it will slide off the bush quite easy. 7- loosen clutch cable adjustment & remove cable nipple at pedal. 8-remove clutch pedal. 9- pull brake pedal out of plastic insert, this will break there is no way to remove this without breaking the plastic clip. get a new brake pedal clip insert for a Mk 3 golf £4 its the same (dont let VW sell you a new pedal) 10- remove 5 x nuts holding pedal box to bulkhead/brake servo. 11- cut 2 x cable ties holding throttle wiring & disconnetc plug above heater on drivers side. 12- push/pull brake servo slightly out of bulk head. 13- remove pedal box.
Cause of the problem- The clutch bracket is only held to the pedal box with 2 x spot welds & a 10mm tack on the top corner.
Repair- Fully Weld the clutch bracket to the pedal box. Great repair.
refitting reverse of above.
Duration around 6/8 hours Less if you get the spare parts before you start.
I wasted time trying to remove the brake pedal without breaking the clip impossible to do even with theVW tool. £4 on a new clip is well worth it.

Abs and t/c lights are on have had full break job done both front and back wheel sensors are working but when coming to a slow stop I feel the car start to grind like if it needed breaks I can feel this...

When there is such a feeling, it is the brakes that needs total replacement.

Also you might have to check the master brakes for any leaks. And you need to check the bushing rubbers on the steering rack too.

Be careful and fix this on time.

Driver Side Power Window Suddenly Went Out!

This is a very common problem with the cadi's. First you have to remove the panel so you can test right at the motor switch. The panel is hard to get off on the cadi's. Behind the door handle there are two clips that are metal and need to be bent upward to releave the pressure. The first clip can be reached by removing the switch housing and you will see the clip towards the rear of the opening. This same type clip is located about 6 inches farther back. The best way to reach this one is by looening the panel and reaching in from underneath with a wide flat tool too push up on the clip while pulling out on the panel lightly. Once you have the panel off, the sound barrier has plastic pop rivets holding it in. Do not pry these off or they will break. Push the center of the rivet in slightly and it will releave the preasure of the rivet and then it will release and you can reuse the rivets. Now that you have the sound barrier off you can test you switches from the motor plug. Unplug the motor and use your volt-meter on the switch side to take your readings. Most likely the regulator has a broken nylon slider. Do not buy parts from the dealer, the regulator cost over $300.00, by your regulator from my website for about $55 shipped right to you. Go to and click on new parts at the bottom of the page. Also check my blogs for other repairs . Hope this information was useful.

How do I replace headlight on 2006 subaru tribeca

To remove light bulb from Tribeca B9 low beam simply 1) remove outer cap, 2) reach into round cavity holding bulb and disconnect two leads, 3) then press on one end of wire clip--the one with the larger bracket (use mirror to view then go by feel) and while pressing on wire move outward away from bracket and clip will swing up and out of the way while being held from falling away by screw on other side of bulb socket. 4) pull bulb out noting that there is a tang which goes back in the same location. Driver side is easier if you remove battery. Other side only requires you remove air intake vent to air box ----- two pop-outs hold it in. Do not take the front end of the car off or light unit out as suggested above.

I need to replace the headlight bulb how do I do this without getting a shop to do it?

The clips will pull up. They are shaped like an "L", only upside down. If you look down on the clip, you will see there is a notch that is locking it in place. I found that if I took a screwdriver and placed it in the notch, pushed out a little, and at the same time pulled up, the clip would pop loose. Hopefully, this helps.
