My car listed above XLS model, turn signal stop working on the rear driver side but the right rear, and both front signals work, I checked the bulb socket with a meter and no voltage is present. Could my flasher be bad?

Yep, I have seen this problem before, so you have a light failure sensor that needs to be replaced. Here is the location so you can fix it. Check out the images (below). Please let us know how it goes.

Hello Ken L, I located the sensor and priced it, wow it is very pricey, is there any way I can bypass it? If not, I saw some used ones on Ebay I may have to take a chance on a used one.

Yep, we have had good luck with Ebay parts so far. It does look like you can bypass the sensor, here are the wiring diagrams so you can see how to connect the wires directly. Just leave the bulb out warning light disconnected. Check out the images (Below). Please let us know how it goes

Hello Ken L, today I received a used sensor from Ebay and I installed it but it did not work. My left rear turn signal still doesn't work so before I try to bypass the sensor can anything else be causing the problem?

Yes, the switch can cause the issue, sorry the sensor didn't work we just had this problem in the shop, and it fixed it, you can use the test light to check the switch output on the grn/blk wire to confirm the failure.
