#1 of 9 Driver Information Center Repair

1999 Chevy Venture Driver Information Center Repair.
I researched and finally found a fix for non functioning Driver Information Center.
The solution was similar to that found for similar modules on other brands of vehicles.
Remove the Driver Information Center Module
(See GM manual for procedure)
Push back clips from black housing box and carefully remove circuit board
Place circuit card flat on table.
Place display and component side of circuit board facing up
Rotate circuit board so the display module side is facing you
There are button switches on either side of the display module
Look at the right button switch.
Next to it just left and above are four 1/4" X 1/8" black components attached to the circuit board
They are marked 430, 430, 820 and 820 reading from top to bottom.
These are resistors with 43 and 82 ohm values.
On the two modules I have repaired the problem was with the top most resistor. It is marked 430 and is 1/2" above and 1/4" to the left of the right button switch. The soldering to the circuit board had fractured. I resoldered the resistor into place using a bit of solder and 15 Watt pencil soldering iron.
The problem is NOT the black spot on the display in the upper left corner
The problem is NOT the DC to DC converter modules.
Why does it come loose?
I believe the resistor was part of the circuit which supplied power to the display module plates.
The resistor came loose due to the metallurgy of solder. The solder often is a mixture of tin and lead. The tin is more strongly attracted to the copper in the circuit board than the lead is attracted. When hot, when within 10% of melting temperature (resistors designed to run hot), the tin near the circuit board face will move. Having moved there is stress in the solder at the locations where it left. These holes create high stress in the solder structure, this leads to a fracture staight across the mounting face of the resistor as smooth and complete as if a knife cut the resistor loose. This only happens in designs which allow parts to heat to values close to the melting point of the solder. This rarely would happen in the past before surface mounted components. The cure would be higher temperature solder, cooler running parts, avoiding flat straight mounting interfaces, etc. Reheating the joint sets it right for a while.

Thank you very much mauricehl. I did exactly what you said and everything worked fine. I just resoldered the two 430 resistors.
My driver information Center was not working for the last 1 year. Since it was working sometime for couple of minutes, I was kind for sure that it could be some kind of dry solder or loose connection,Since I was not sure about that , I didn't do anything until today.
Thank you again for the detailed instruction about how fix this issue.

Glad to help with the DIC VFD repair,
now just be careful watching the inst mpg readout. Keep you eyes on the road.
after putting on goodyear fuel max tires and putting them at 42psi, I got 32mpg at 50mph, 28 mpg at 62 mph.
anyone do better?

This was awesome information! It is totally correct, I just ended up paying $30 for a used DIC on ebay with no progress with the problem. But after reading this blog I took my old DIC out and plugged it in and pushed down on the 430 resister which was hard to do and bang it light up and worked. So now all I need to do is try and fix it. I have done very little soldering, so I will cross my fingers and hope for the best.
Thank you so much for the information!

You are very welcome,
I enjoyed driving with the center functioning.
Glad it worked for you.

I don't see the damage to the resistor that you speak of... Can you look at my picture and tell me if I'm on the right track. Sorry for being the slow one of the group

HEY TAWNYG, THANK YOU SO MUCH FOR THE AWESOME INFO!! YOU SAVED ME $300.$$$.. I FOLLOWED YOUR STEPS JUST AS YOU DESCRIBED ON MY 99 OLDS SILHOUETTE AND IT WORKED GREAT JUST LIKE YOU SAID.. IT WAS ALMOST IMPOSSIBLE TO SEE IF YOU DON'T KNOW WHAT YOU ARE LOOKING FOR, BUT IT SURE WAS BROKEN RIGHT AT THE WELD.. THANK YOU SOO MUCH.
