DIC and Heated seat problem

Did you have the oil changed lately ?
Oil Life Left
Oil life left percentage is based on the information the DIC receives from a class 2 message from the PCM. The DIC displays the current percentage of the GM Oil Life System. When the oil needs changing the change engine oil indicator in the message center turns ON. When the engine oil is changed, reset the oil life left. Refer to GM Oil Life System Resetting in Maintenance and Lubrication.

GM Oil Life System Resetting
When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE ENGINE OIL message will come on. Change the engine oil as soon as possible within the next 600 miles (1 000 km). It is possible that, if driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, the engine oil and filter must be changed at least once a year and at this time the system must be reset.
If the system is ever reset accidentally, change the engine oil at 3,000 miles (5 000 km) since last oil change.
How to Reset the Engine Oil Life System
If the vehicle does not have optional Driver Information Center (DIC) , do the following:
Turn the ignition to ON, with the engine off.
Fully press and release the accelerator pedal slowly three times within five seconds.
Turn the key to OFF. If the CHANGE ENGINE OIL message comes back on when you start the vehicle, the Engine Oil Life System has not reset. Repeat the procedure.
If the vehicle has the optional DIC, do the following:
Turn the ignition to ON, with the engine off.
Press the MODE button until the DIC reads OIL LIFE LEFT/HOLD SET TO RESET.
Press and hold the SET button until 100 percent is displayed. You will hear three chimes and the CHANGE ENGINE OIL message will go off.
Turn the key to OFF.
If the CHANGE ENGINE OIL message comes back on when you start the vehicle the Engine Oil Life System has not reset. Repeat the procedure.

Oil Life Monitor Resetting (KD, KE)
Description
The engine oil life monitor will indicate when to change the engine oil and the engine oil filter - usually between 5 000 km (3,000 miles) and 12 500 km (7,500 miles) since the last oil change. Under severe conditions, the CHANGE OIL message may be displayed before 5 000 km (3,000 miles). The vehicle must not be driven more than 12 500 km (7,500 miles) or 12 months without an oil change.
The engine oil life monitor will not detect dust in the oil. If the vehicle is driven in a dusty area, be sure to change the oil every 5 000 km (3,000 miles) or sooner if the CHANGE ENGINE OIL message is displayed.
Reset the oil life monitor when the oil has been changed.
Resetting Procedure
Press the INFORMATION SKIP button on the DIC control panel in order to display the OIL LIFE LEFT message.
Press and hold the RESET NO button until the display shows 100% ENGINE OIL LIFE.

On the DIC, select gage-->Tire Pressure, then press and HOLD the RESET button until it resets (about 3 seconds).

Check your fuses first. Then check to see if you have power to the box under seat. It should be about 3x3 and black I think. If you have power to the box change the box. To check use a test light. make sure the key is on and the button is pushed then probe the wires going to the box. Hope this helps you.

Labatche822,
The process for resetting your Tire Pressure Monitor (TPM) is below.
Good luck, let me know.
Regards.

To reset (calibrate) the system:
1. Turn the ignition switch to RUN.
2. Press the GAGE INFO button on the DIC until
TIRE PRESSURE appears on the display.
3. Press and hold the DIC RESET button for about five
seconds. After five seconds, the display will show
TIRE PRESSURE RESET. If TIRE PRESSURE
RESET does not appear on the display after about
five seconds, see your dealer for service. After you
release the DIC RESET button, TIRE PRESSURE
NORMAL will appear on the display.
The system completes the calibration process during
driving. During the first 10 to 25 miles (15 to 40 km) of
driving, the system will not alert you if a tire is high or
low. After 25 to 100 miles (40 to 160 km), the
system will only alert you about pressure differences of
12 psi (85 kPa) or more. After about 100 miles (160 km)
of driving, the system will alert you if one tire is
10 psi (69 kPa) different from the other three tires.

- To reset OIL LIFE message, press the ENG. button with the ignition on until OIL LIFE percentage is displayed.
- Press the RESET button for 5 seconds.
- RESET will appear and then OIL LIFE 100%.

When the system is on or off, push the ON/OFF button down for three seconds to change the display between English and metric. This will also change the digital screen for the climate control system between English and metric.

The heated seats have relays that run them. Not quite sure where they are located but. That noise is the relay clicking on and off. They are actually pretty loud. Look for faulty connections to and from the relay and check battery power to both sides of the relay.

This is in the user manual, sorry best i can say,

A common cause for the heated seats to not work is a burned heater element. There is an element under the seat cushion cover, and one under the seatback cover. If either has failed, both will not work.
