WATCH HQ VERSION http://youtube.com/watch?v=npIFgZKYRcI&fmt=6
It's the best it's going to get. Another HQ video uploaded to youtube turns to crap...

The digital climate control has a diagnostic function that shows different things like speed in mph, engine rpm, temps, etc.

Here's the ones we found thanks to the guys at impalassforum.com (these include the ones shown from the shop manual at the end)
-02 HVAC Trouble Codes
-05 Program #
-06 Tachometer (RPMs / 100)
-07 Commanded Blower Speed (0-128)
-08 Coolant Temp (°F)
-14 Vehicle Speed (MPH)
-15 Temp Cal Offset
-18 Sun Load Sensor
-20 Current Temp Valve Position
-22 Temp Valve Position @ Cold
-23 Temp Valve Position @ Hot
-24 Coolant Temp (°C)
-25 Commanded Temp Valve Position
-27 Air Delivery Mode
-28 Inside Air Temp (0-255 where 128=75°F)

@Dunoj I believe those two numbers are temperatures taken at two different locations (cylinder head vs water pump). Not 100% sure though.

Caddy's have used this since 1980.

[MrCadillacLT1]

Have to reset it every time you turn the car on.

[FatGuyWithAKatana]

[Dunoj]
