Question about 2003 Chevrolet Tracker
I tryed to test the fuses, but im not sure if i needed to put my accessories on to test it? my car is 5 speed manual. Also not exactly sure which fuse is for back up lights... any idea?
The reverse lamp circuit will be separate from your other lights. Usually, it is not a separate fuse, but may be ran off the ignition fuse.
If you are testing fuses, the accessory does not need to be on. A few fuses will be hot at all times-like the brake lights, don't need the key on, brakes work all the time. The other fuses will be powered anytime the key is turned to on-whether accessory is on or not, fuse will be live when key is on.
Have you checked the bulbs? If you pull a bulb out, you could check for power at the socket with a test light. Key needs to be on, and gear placed in reverse. Socket should have power to it. If not, and you can find the reverse switch, pull off the connector, and check for power to the switch with key on. It should have power to it, and only pass power through the switch to the reverse lamps, when car is put in reverse.

No they should only come on when you put in reverse or else everyone would think you were backing up! its your bulb if just one, the fuse if both or the reverse switch indicator... Good Luck

Back up light switch is located on the rear of the transmission, easier to find if the LF is jacked up and wheel is removed. My switch was working fine out of the transmission, but was about a !/32nd of an inch short of closing when in reverse.
The way I determined that was by using a depth gauge between neutral and reverse, is a pawl inside of the transmission that goes rearward, and by comparing the decreased depth with the contact closure of the switch, was about 0.30" too short of closing, used an ohmmeter to determine when the switch was closing.
Now maybe by finding a switch at the dealers that closes with 0.030" less movement would solve that problem or trying to get more backward movement on that pawl. Now that would be a job to disassemble the transmission and bending that pawl backwards a tad. So I just put that switch in my machine lath and took off about 0.060" off the shoulder so it could be screwed in further. It's been working fine every since. I could barely get my baby finger in that switch hole to check for free play, was pretty tight. Just an engineering goof in my opinion, not allowing enough tolerance for switch closure variations. The plunger of the switch still had a good 1/8th " of movement after the contacts closed.

SOURCE: reverse light not working
There is a sensor that connects to the light shifter which tells the car when it is in reverse. It may need to be replaced. You can remove it and check it with an ohmmeter or voltmeter to see if it is good or not.

Check the brake light switch under the dash attached to the brake peadal arm. It is wher the break booster push rod attaches. Sometimes that switch works loose.
