Your diagnostic circuit is detecting a problem somewhere in the set and shutting it down to protect the remaining good circuits. Check the power board for fault it is usually the culprit. Look for capacitors with spewed up tops. They may also be leaking a oily like substance (electrolyte) and when replaced will fix it. If not then your problem could in many places. Look at the power board first and see if the voltages are coming off it if the capacitors are OK.
If not then nothing else on the board can be fixed. You will have to order another. If I can help with anything please feel free to contact me anytime.

My right front turn signal on my 1997 fordf250 truck will come on but will not blink. I have replaced the bulb and bulb socket but it did not help. What could be my problem?


The other turn signals front and rear work ok? Disconnect right turn signal, with that signal turned on, use a test lite on the white wire with lite blue tracer, does the test lite pulse?
Does the right turn indicator on the dash pulse on and off?

Is Blue Lite For High Beam Supposed T oStay on when clicked?


To clarify, when you pull the turn signal lever towards you, the high beam lights will come on only as long as you hold the lever up. This is the flash to pass feature.
To switch the headlights from low beam to high beam, you push down on the lever towards the dash. Then the high beam lights and the blue indicator light should stay on.

This is a classic switchmode power supply, has sensed a severe potential problem, and is shutting down to avoid a fire, explosion, or both. This set had developed a problem, that is so severe that the set must be shut down, This set should be removed from the Power, and in my professional recommendation, you should get a "Quote" for repair, from, an, Approved Service Center, this point is very important for a good result, Always contact, their local, "Head Office" Now, when you get the information you want, then you can decide as to repair of replacement. The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand, also sometimes, there has been a service bulletin in issued and the repair may be subsided or even free. There are many, many, many reasons that display this symptom, one must work through the troubleshooting steps to isolate and identify, the Cause and repair that and any damage done
