My 2005 Excursion had an intermittent problem. Occasionally, the blinker would stay "on" and would not blink.

The shop manual diagnostic chart led me to replace the "multifunction switch" (turn signal stalk) at a cost of over $130. I also inspected the wire cable under the steering column cover and wrapped it in electrical tape where it could possibly chafe. This "fix" did not work.

Finally, I realized that this condition never occurred right after starting the truck. It only occurred after the blinker had been used a few times. In other words, it appeared that something was getting hot.

I purchased and replaced the "flasher relay". This relay was very hard to locate. It is in the dash behind the radio. It is blue, but it resides with another relay inside a black plastic box about the size of a pack of cigarettes.

Problem solved. The new flasher relay has been in for over 8 weeks without a recurrence of the problem.

The part number is 5C3Z-13350-AA. Description is "Relay - Direct". I paid $31.12 plus tax.

 

Napa also has the flasher EL-27, I believe. I replaced mine thinking it would fix my trailer light problem. Turns out that the factory had crossed the ground wire in the trailer.

 

Well at least you use your turn signal. Seems to be becoming more and more rare. I think that it is either laziness or lack of coordination on the modern drivers part. Thank you from the rest of the "Users" and thanks for posting the fix.

 

LOL - I agree with you 1000%.
Plus it's hard while texting & eating to have a free hand for the turn signal.

I tell folks "modern luxury cars are so expensive, nobody buys the optional turn signals any more".

My wife even points out cars that "didn't buy the optional turn signals".

 

i am also going through this dilema.....replaced the stalk as well and it still happens......cant for the life of me find the relay but ill go look behind the radio now.....thanks......

 

Sorry, I did not take any pictures. You may be able to get to it by removing the "bag holder hook". I think it is below radio and toward driver side. Use a bright flashlight to look for this black plastic relay holder.

 

Here is a link to a thread by nomad27 on fuel pump relay that shows a photo of the blue flasher. Hope this helps.

im a bit of a demolition expert so i wanted a good view and took out the whole dash bezel.......

here is the box right next to the factory harness for the brake controller.......
