Before you dig into your dash, there are other, easier things to check first.

First, what exactly are the t/sigs doing/not doing?

Usually if you have a bad dash printed circuit trace, it either works or it doesn't.
Check these:
If the t/sigs work intermittently, I would suspect a dirty/corroded plug at the steering column, a bad flasher, or bad/corroded grounds.
Do your emergency flashers work?
Do all your front and rear bulbs work? The brake and T/signals use the same bulb filament in the back. Your emergency flasher will tell you if the bulbs and wiring are good. (including the dash indicator lights)

There are other possibilities but lets start with a little more information.

Haven't been on the forum in a while. Had a lot going on this spring & summer, so I've just been lurking around. But... Did get the coach!! She runs very well, and still sorting out a couple of things - Onan, temp gauge, steering box, sticky idler arm, windshield washers/wipers, seized parking brake - all of which I can sort of work around and am in process of getting replaced/repaired. But one I am wanting to deal with before I take her driving again is that the turn signals are intermittent (actually barely intermittent - mostly not working at all). PO told me this after I got her home. And it has gotten worse. (Hard to tell sometimes if the darn things are blinking at the best of times!). He told me that the "It attaches to the instrument panel PC board. It appears that the copper on the board is worn away" and isn't making good contact consistently. Before I go ripping the dash apart, could someone point me in exactly the right direction? I am more than willing to play, but not interested in tearing down something that I really don't have to. Can't really find the location in the maintenance manual unless I'm just missing it (more likely than not).

Next question of course is - can the connection be resurrected! Or would I need to get a new board?

Anyone have a picture of the board in the photos? So I actually have an idea what I'm looking at Smile

Cheers.
