1999 Pontiac Montana DIC is dead. Got one from junk yard and get only "--" for data. Any help? Do these have to be factory repaired?

You can try performing a diagnostic self-test of the DIC.

In order to perform the diagnostic self-test and reset the driver information display, simultaneously press the following buttons for at least 2 seconds :

The reset is acknowledged with the display showing all segments ON for 1 second . You may only reset the following modes. The reset affects all 3 of these modes simultaneously:


If all of the segments light as described above, but the same symptoms are still present follow these instructions:

Symptom: Driver Information Center (DIC) Always Displays Dashes

1. Check for a poor connection or an open in circuit 800 (Tan wire) between the DIC connector terminal 15 and the Powertrain Control Module (PCM) connector C1 terminal 15.
2. If a problem is found with the circuit in step 1, repair the circuit and retest. Otherwise continue to step 3.
3. Replace the DIC and retest

Clock and radio info will not display and the compass/temperature/mpg will only show occasionally

clock, radio & DIC display is out. What do I need to do to fix this problem? Is it some kind of fuse?

The Driver Information Center (DIC) 99 Montana is out

I am assuming that the DIC does not "power-up" at all.

Check your owner's manual to see which fuse powers the DIC. If the fuse is OK, you need to get your hands on a wiring diagram and remove the DIC from the dash so you can check to see if you have a good ground on the ground wire to the DIC. Then check to make sure you have battery voltage to the B+ circuit to the DIC. If the proper voltage and ground are present, you will have to take the DIC to your local dealer for repair. Many GM dealers have an exchange program where you can turn your old DIC in and get a "remanufactured" one on the spot. Others will send your DIC out for repair and call you when it is returned to them.

I have a 99 montana passenger side sliding door dont work. Hit either button all it does is clicks and motor seems to be fine.. I went to junk yard bought complete new motor and everything that comes...

I would check the overhead buttons there are two one opens the door, and the other beside it that shows the van crossed out, disables the electric sliding door feature. try playing with that, Also remember, that vehicle must be in PARK for the electric sliding door to open. Make sure the power lock on that door is working, and check the child safety lock when you have it open by the doors catch. Hope that Helps You.

DIC doesn't work

Are you talking about the one in the roof console, near the windshield?
With the key OFF:
Depress and hold the MODE and the ENGLISH/METRIC buttons.
With these two buttons still depressed, turn the ignition switch to the RUN position.

When you do this all display segments will light for 2 seconds then off for 2 seconds, then it should show "PS" then turn off. After this, then unit may show E1, E2, E3 or E4. If E and a number (E1) didn't come up, then there are no errors in the System.

Turn the van off, set the compass, find your location on the map picture. The number you fall under is your zone number.

Turn the ignition ON.

Cycle the driver information center (DIC) to the Compass/Temperature mode.
Press both the E/M and the MODE buttons for approximately 5 seconds.
The last entered variance zone number will be displayed.

Press the E/M button until the proper variance number (See picture) is showing.
Press the MODE button in order to set the new variance zone and resume normal operation.

Note: The features are controlled by outside data. The only feature that is self contained in the unit is the compass, and if it is not working correctly, then the unit is malfunctioning and I would suggest replacing it with a new one.

Perform these steps on more time. If it still does not work right, then the unit will need to be replaced.

Turn the ignition ON.
Cycle the driver information center (DIC) to the Compass/Temperature mode.
Press both the E/M and the MODE buttons for at least 10 seconds until the calibration symbol appears.
Release both buttons once the calibration symbol appears.
Complete 3 360° turns in an area free from large metal objects.

But I would wait before replacing it. Drive it around normal for a day first. If it nothing happens then, then replace it. The compass will not always calibrate right away.

Good luck and hope this helps.
