[s-cars] Noisy Dashboard 1992 S4 and LCD Questions

[Keith Maddock]

James/Bob..

I had this problem with my HVAC controller too.  I took the display apart a few times, and put stabilant-22 everywhere I could imagine.  It fixed it for a few days, then was back to the old garbled display...

I fixed it by buying a new HVAC controller from a wrecking yard, not cheap.. :(  In the end it was worth it because it was very visible to everyone that rode in the car (as well as bothering me).

Cheers,
Keith "Car-less in Detroit" Maddock

James:
Try a little stabilant 22 where the rubber feet of the contacts meet the
LCD.

My problem is the display in the heat/AC controller below the radio, it
seems to be affected by humidity!?

When it's humid the LCD lights up correctly, but when the air is dryer the
digits do not display correctly and I haven't been able to figure out how to
fix it. I've had it completely appart ! I mean completely.... But I could
not see the problem. I guess there's a small contact issue in the LCD glass
but I'm not sure how to fix this?

Anyone?

Questions

	Hi Cody,

	Discussed the LED problem with a colleague this AM.  He solved his
by
	removing and disassembling the dash, and applying a contact enhancer
to all
	the exposed solder joints and connectors.  I think it is called
"Stabilant
	22  (Brent, can you confirm?)  Not only solved the LED problem, but
now says
	all displays are brighter.

	As for the rattles, every time I re&re my IC, I have different
noises left
	over.  The factory uses ties all over the place when they are
originally
	assembled.  Just try to make sure all loose cables are tied firmly
in place,
	or padded in areas that might move around.

	HTH

	Gents,
		Is there any cure to a noisy dash board?  Seems to creak,
and rattle a
	little bit when driving.  Sort of annoying.  Seems to come from
right over
	the console.

	-2nd Question:
		My LCD display on the dash seems to be going out or is very
sensitive to
	hot temperatures in the car.  It pretty much doesn't display
anything that
	is legible except in the AM I can make out "OK"  I had a similar
problem on
	my 1998.5 A4...

	Thoughts?

	Thx

	cp
