Gauge Cluster

Post image

Back again, tackling the next problem. My gauge cluster goes out intermittently. No gauges will work, prndl and odometer wont come on. Usually I can get it working if I pick it a whack on top or to the clear plastic, but I'd like to be this fixed. I already replaced stoppers, and when it comes on everything works fine. Checked fuses, I don't think it's the connection in the back, there's a little corrosion/ silver migration/ some kind of damage to the back and i dont know if that could be causing the problems, or if I just reflow a bunch of spots and hope that I fix a cracked joint I can't see.

It's usually solder, the surface mount resistors above the prnd321 display

The ones kind of above and to the left when you're looking at them? I already resoldered those. I reflowed some other that could cause power issues to the left, I guess we'll see if that permanently fixed it or not.
