Try replacing bulb first, if that doesn't help look for a poor connection like a broken wire or corroded bulb socket.

    I tred changing bulb and cleaning contacts and still don't work : I cannot find backup lamps in criut in book

    The next step would be to folow wire back to wiring harness looking for a break, and check ground, you may have to remove whole light assembly. You can use test light to help finding power wire. Wiring can take time to trace problems.

My 2001 Pontiac Grand Am GT reverse light does not work on my driver's side. I need to get it fixed by the end of this week in order for me to pass the safety inspection. I need help fast!


Backup Lamps
Vehicles equipped with an automatic transmission, the BU LMP fuse in the IP fuse block supplies battery positive voltage to the park/neutral position switch. Vehicles equipped with a manual transmission, the BU LMP fuse in the IP fuse block supplies battery positive voltage to the backup lamps switch. When the driver places the gear selector lever in the REVERSE position, the current flow is from the park/neutral position switch or the backup lamps switch, to the back up lamps. The backup lamps are grounded at G401 and G402.

Where is backup light switch on 01 impala


Backup Lamps
The B/U LAMP fuse in the RH I/P fuse block supplies battery positive voltage to the switch terminal of the backup lamps relay. The DIC/RKE fuse supplies battery positive voltage to the backup lamps relay coil terminal. When you place the gear selector lever in the REVERSE position, the powertrain control module (PCM) sends a class 2 message to the body control module (BCM). When these conditions occur, the BCM energizes the reverse lamp relay control circuit, closing the switch contacts, the current flows from the reverse lamp relay switch to the backup lamps. The backup lamps are grounded at G302.

There is alot involved in turn on the back up lights .
DTC B2552
Circuit Description
The body control module (BCM) controls the backup lamp relay. The BCM grounds the backup lamp relay control circuit which energizes the backup lamp relay.

2
Install a scan tool.
Turn ON the ignition, with the engine OFF.
With a scan tool, command the backup lamp relay ON and OFF.
Does the backup lamp relay turn ON and OFF with each command?
YES - Go to Diagnostic Aids
NO - Go to Step 3

DTC B2553
The body control module (BCM) controls the backup lamp relay. The BCM grounds the backup lamps relay control circuit which energizes the backup lamp relay.
Turn the ignition ON.
Shift the gear selector lever to the REVERSE position.
Do the backup lamps turn ON?
YES - Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems
NO - Go to Step 3
3
Remove the backup lamps relay.
Connect a test lamp between the battery positive supply voltage circuit of the switched side of the backup lamp relay and ground.
Does the test lamp illuminate?
Before replacing parts you may not need , take your vehicle to a qualified repair shop .

Right side headlight on 2006 pt cuiser wont work


make sure you seated the lamp correctly and returned the socket to the correct position. Try another bulb (new ones can be bad). Check for broken wire at back of socket.

Right rear brake light and blinker not working


Daniel,

Should still be under warranty. If you have determined it is not a burned out bulb, let the dealer trouble shoot.

Some other things to check, from a wiring standpoint, does the right side emergency flasher work? Does the right side backup light work?

If these do not, I'd look for a connector to the right side of the rear that came loose. Haven't spent that much time under my 2009 (same model style), but I'd suspect on a jeep that physically following the wires to a connector would not be hard. Also could be a ground issue to the right side lamp housing.

If those are working, morelikely a broken wire.

Access to right side backup lamp wires


  1. Usually the trim has several clamps behind the trim to connect to the body, use screw driver pup it up slowly.
  2. Maybe you need to take off the ceiling panel,
  3. Take the panel off, usually have several screws behind the handles, seat belt mount bars, pup the small plastic cover up on those bars and you will see the screws.
  4. step by step install you unit.
  5. Hope this can help. good luck
