Rearview Mirror Blinking

Before posting, I did a quick search and came up with an earlier thread that was never resolved ( http://jeepgarage.org/showthread.php?t=18989 ) but I'm having the same issue.

The light on the power button for the rearview mirror flashes on and off, regardless of whether the headlights are on/off or anything else I've tried. Attempting to power the mirror on or off does not change the flashing light.

The above thread mentions aiming the lights, which I think must be my issue. As we speak I have two new entire headlights coming in as replacement parts because the motor in both light units broke, leaving the headlights aiming much too high.

However, before I go inquire at Jeep today, does anyone have any suggestion/tips? I'm not entirely sure that the flashing started when the motors in the lights broke.

Background: a car backed into the front of my Jeep accidentally when parked on a hill, which evidently is enough of a hit to break both lights.

Thanks guys.

No. That thread said "I don't know exactly what the dealer did, but they had to aim the lights or some type of sensors inside the Jeep to fix the blinking light."

The rearview mirror sensor points backward to detect the headlights of cars behind you. This has nothing to do with your own headlights.

This is a separate problem. You should tell your dealer about it.

Re: Rearview Mirror Blinking

The blinking led is for the smartbeam system,which has the camera attatched to the mirror and it faces out the front of the windshield to detect the headlights of oncoming cars.The led blinks 2 different ways and this is straight from the service info-

SmartBeam® uses a blue-green Light Emitting Diode (LED) unit that also illuminates the ElectroChromic (EC) inside rear view mirror power button to indicate certain faults it detects in the imager camera and circuitry. A slow (once-per-second) continual flashing of this LED indicates the SmartBeam® camera requires aiming. A fast (twice-per-second) continual flashing of this LED indicates that a SmartBeam® fault has been detected and a Diagnostic Trouble Code (DTC) has been stored. The EC power button is located on the lower front of the EC inside rear view mirrors.

That's very helpful. Thank you very much. I'll mention that at the dealership this afternoon.

Thanks for the info. Mine has the fast blinking situation and my high beams will not go on automatically in the automatic position. My dealer thought I did not have the beam stalk in the proper position but ordered a new mirrror for me due to the blinking light on the mirror.
I faxed him your answer today.
