I've got a similar (sort of) problem in our Toyota. In it, some of the led display lights for fan speed control, part of the dash lighting and a few other things doesn't come on immediately when you turn the lights on. Eventually they all come on at the same time. This indicates to me there is a bad connection someplace. Yours too probably. My guess for mine would be a break in the ground. (just a guess though) Now I could pull the panels, clean all the connections and see if that fixes it. (you never know though, it might also make it worse) That is, assuming I care to fool with it at all. Unfortunately, the problem could be anywhere. This is why repair shops most always replace everything. So, I guess what I'm saying is to consider carefully weather or not it's worth the risk. Everything still functions now. It may not anymore if you try to fix it. Sorry I haven't got an easy answer for you but it's just the way things are made these days.

I just had a similar problem with my 95 pa, it ended up being the control head itself, you can take it out, take two screws out and circuit board will slide out then check the solder joints.

I guess I gotta take the whole dash out to get to it. Thanks fer your reply......JOE

It's really not as hard as you think, most of it just snaps off.

I've fixed those, by reheating the input solder joints-- and also by tapping on the control head with a wooden hammer handle- sometimes it will go 3 months on a hammer hit--- but then you need to go inside and reheat the solder joints.

I have a 03 PA ultra, with the same problem on the climate control unit display. But it's also happening with the heads up display. So does this still sound like same problem u guys are having with the soldering?
If yes does anyone have a pic of the joints that need to be re-soldering?
