Yep, cracked solder joints are the bane of otherwise reliable electronics.
Sometimes I wish our vehicles were not SO electronic. If we could combine the better mechanical reliability of modern engines (better lubricants and fuels are maybe part of that) with the simplicity of older vehicles...
Ye, I just resoldered a couple of known bad solder joints in the clock on my Honda CR-V. So many failures there, there are folkd on ebay who offer to do it for $14 postage included lifetime warranty. I opened mine up and with a 6X Loupe the cracked solder was plainly visible. Also fixed a Volvo...
Yep.
I've re-soldered joints on relays and clocks and it would not shock me if this is the problem.
I'll start poking and prodding and pulling at things, and maybe it will come to the cluster board. I'd prefer not, but it will be what it will be.
Thanks for the suggestions

Sorry, I should have been more specific.
It's just the background lighting. I didn't know if maybe it's a somewhat common problem like a faulty brightness control (probably not a simple rheostat like the old days) or a particular junction, ground, or harness that might ne "known" by a few folks...

Driving, the cluster just winks out completely, sometimes for a couple of minutes, and other times for 10 minutes or so. It always comes back on whether later in teh drive, or when it is started the next time for use.
The Master Warning is on, but no lights to say WHY the master...
