2001 cadillac sts reverse lights and license plate lights not working

SOURCE: Light Bulb Replaement

I just replaced the license plate lamps on my 2004 Deville DTS.
Lamp is PC195. Lamp PC168 will also work, (it was in my car for the last two years), but it is a brighter bulb than needed.

You pop out the lamp holders by pushing (sliding)the right side towards the left. That little push will unhook plastic tabs from the sheet metal and the right side of the lamp holder will release from the trunk. See the attached photo.

To push the lamp holder, I used a narrow putty knife covered with masking tape. A screwdriver will work as well. The masking tape protects the paint from scratches.

No it wouldn't be a fuse because it's partially still working,LEDs are wired in series so it could be one LED is burnt out or the current limiting resistor has opened for that section.Repairing it would be fairly simple but will require a multimeter preferably with a diode tester and a soldering iron.If you're not familiar with using a multimeter and testing electronic circuits I would say let a professional repair it or replace the whole unit.Comment back and I will give you the test procedures if you fell confident in making the repair.

on the positive battery cable under back seat is a red device with small orange and bule wires called a thermister controls alt output.this device is no longer availible from gm good news is you can buy a resistor of 1600 ohms from radio shack for lees than a dollar plug it in to connector instead of the thermistor and chargeing goes back to normal. radio, windows ,cruise, control should go back normal also

SOURCE: how do you replace license

Hi,
First you have to take out the one and only screw in the rear hatch door - it's where the hand pull down is you use to close the hatch.
Then you have to pop all the plastic clips all the way around the plastic door panel, trying not to pull them out from the frame . If you do pull out the white plastic plugs from the frame you better make certain you take them off the plastic housing and insert them back into their frame holes - or you will never get the housing back on.

Once you have the housing loose disconnect the inside tail gate light wire to remove the whole thing. Then you have to remove 7 to 8 nuts from the back of entire License plate, back up bulb housing using a deep socket to get in there. Work it loose from the rear of the car and it will come out just enough to work on the lights.
This is tricky since the screw mounts don't give you much room to work with.

Once you have the license plate and back up bulb frame loose you will see the two housings for the license plate bulbs on top.

Slide out the license plate bulb lens and twist the bulb connection to remove the bulbs.
Replace both of them - you don't want to do this again in a month when the other one blows.

OPTIONAL:
Once you take out the bulbs you might see that the housing is melted where the bulb wanted to burn through. Drill two small holes one is each end of the housing before I put everything back together to release some of the heat.

Reverse the whole process to put everything back together. It's not easy.
Make sure you insert the cables through the opening for the hatch handle or it will kink and not work properly.

The bulbs come in a two pack of cost $4.95 .

Take care
