No instrument cluster illumination

[superduty4x4]

Somehow lucked out and the local Napa just happened to have 11 #74 bulbs on hand, I will report back if it worked or not.
Edit- that was a fail. The supposedly #74 bulbs they had are as big as the old bulb and socket combined. Back to the drawing board...

Another update, found my service manual DVD and started digging deeper. Per the manual one of the tests is to measure the voltage between the instrument cluster C220a-6, circuit 19 (LB/RD), harness side and ground. I did that and got nothing, the diagnostic is "repair circuit." So... where to begin? Remember this all started just from taking the cluster out and putting it back in, no other wiring or anything else has changed.

Final update... on a whim I bought 20 LED bulbs off Ebay for $7.79 shipped on Saturday and they arrived today, pulled the dash apart AGAIN, replaced all the bulbs and voila... everything works now.
Now if I could just get the CD changer in this car to work after multiple attempts to fix it...

New issue if anyone is still following... turn signals work on the outside just fine but no indicator lights in the dash using either the turn signals or the hazards. Any suggestions on this one?

All the bulbs in the twist-lock plugs have been replaced with LED's already. I may try the incandescent bulbs in the turn signal spots to see if they come back.
Not one thing I've done to this car has been easy, it's really starting to wear me out!

Doesn't the LED's fit in where the bulb for turn signals etc is? Might as well make it a permanent fix with LED's, there's no way of knowing how long an old incandescent bulb will work..


BTW, which LED's did you get?

All 11 bulbs in the twist lock plugs were replaced with LED's. Turn signal indicators, high beam indicator, and cruise control indicator are not working. Could someone do me a favor and take a picture of their cluster in test mode with all the indicators lit up so I can see what else might not be working?

Here are the LED's I bought- 20 x T5 Wedge 5050 1 SMD LED Dashboard Instrument Panel Light 74 86 37 70 2721 | eBay. Ordered early evening on a Saturday, arrived on Monday.
