2002 Excursion
Hey guys looking for some help troubleshooting an issue. Just recently picked up an 02' Excursion and there's an intermittent clicking noise from behind the dash no rhyme or reason and sounds like a relay to me sometimes when it clicks it will flash the climate control lights. I have tried to isolate it to what is affected by turning off the climate control screen, but it still clicks? Everything works fine or else i'd probably be able to tell what is causing it.
Thank you for any input you can give.

If it's repeats rather quickly, it may be LED's were installed and the multi-function switch needs to be replaced.
Also if you have LED's the flasher relay needs to be replaced. That was my symptom when I moved to LED's (both parts)

Ahh probably so the PO installed LED's everywhere some flicker and some stay illuminated the turn signal also blinks fast as if a bulb were out, but there aren't. Multifunction switch? as in the entire piece or something different?

Try reversing the polarity of the connector for the headlights...one at a time.

No. ...but the multi-function is the turn indicator/wipe washer stalk.

If I recall it's between the column and the mid, basically past your right knee. It's also where the code for the door is located and that's even more well hidden.

So I replaced the Multifunction switch only to find that didn't solve the rapid flashing. so I swapped back to the old one since it was labeled with a build date of 2016 and returned it. I bought an "LED" relay and replaced the flasher relay fixed the rapid turn signal flashing. I am still having a hard time determining what the clicking noise/flickering climate control screen is.... maybe another relay?
