Climate control panel dead 1987 Park Avenue

[soulbrother]

Hi!
Need some help to troubleshoot the climate control in my 1987 Park Ave. It´s totally dead,no digits,no light,no function. Sometimes the yellow little "dots" flicker for a short moment when turning ignition on or off,that´s all!
Where should I start?

Thanks!

Do you have the in-dash CRT (computer)?
Sometimes called a "touch-screen"?

If you're in Sweden...you probably want to get a
repair manual (Hayes/Haynes/?). The electronics in
these things are really complex and beyond the
scope for most shade-tree mechanics. Most of the
data/info comes from the BCM (body control module)
and it gets distributed to/from various sensors
and relays. Good Luck!

Now it works! I replaced two bulbs in the unit and put together a loose connector - lucky me!!
