Fast Blinking Right Turn Signal on 2007 Lincoln Town Car

[David27]

Hello everyone, about a week ago I noticed that when I use the right turn signal, it starts flashing at a pace that's about twice as fast as normal. The left turn signal is ok, and the hazard lights work with no changes on both sides. Both the front and rear right blinkers are affected.

I ran LCM self test with Forscan and retrieved a couple of new error codes,

B1688 - Lamp Dome Input Circuit Short To
Ground
B1696 - Autolamp On Circuit Short To Ground

I'm wondering if it could be related to the light control module, the lights themselves, or perhaps a wiring issue.

Would appreciate any help!

Check grounds and bulb type. Loose grounds and LEDs will cause issues.

Check to make sure all the bulbs are working. There should be one in the front, and two in the back. I’m guessing one is burned out. As Pocket mentioned, bulbs should be original incandescent.

Oh my I was sure I checked. Never noticed it's 2 per side in the rear. And one if them on the right doesn't work. Will replace tomorrow. Thanks a lot!
