Dic Upgrade

TONYTHOMAS1956 · July 16, 2011

This for all you owners that have done the DIC upgrade on your trucks. Im just wanting to confirm the part numbers as gmpartsdirect will not confirm since my vin number does not show the Dic option.

The numbers i have are 15947842 for the switch and 20935564 which used to be 25905504 and this was in black. Im going with ordering parts seperate since I can save around $20.

Ive done all the reserch I can on line and nothing tells me that these item are in black nor will gmpartsdirect confirm. Its a real pain trying to deal with them in email only. They do have phones dont they?

Your p/n's are correct, but why not just order the switch and cut out the panel you have? That's what I did, and I figure if I can do it....... Just a thought.

I took the liberty of copying some instructions on how to cut out for the switch, if anyone is interested:

"TIPS FOR THOSE WANTING TO CUT THEIR EXISTING DASH:

Remove the dash piece, then remove all the other parts from it; the headlight switch and the air conditioning vent both.

You'll need a Dremel (with an onion shaped bit; round, coming to a point), a triangular file about 3/8" to a side and a flat file about 3/4" or 1" wide. The wider the better for a straight, smooth cut.

Take your time; you've got all day. If you don't have all day, wait until you do.

Cut from the back with a Dremel and cut an opening smaller than you think it should be. Then finish up with sharp files. I only used the Dremel on the initial cut, then put it up. When you cut plastic with a Dremel, remember that speed only melts the plastic. I used speed setting 2 for the best cut without loading up on melted plastic.

Take your time; you have all day.

Make all cuts with a sharp file from the front to the back. This leaves the fuzzies on the back and easily trimmed with a sharp exact-o knife.

Take your time and be VERY careful with the finish on the face. Keep the files away from it and don't lay it face down to file on it!

Try to cut the opening with a slight bevel that leaves the front smaller than the back. This makes final fitting around the switch much easier.

Cut slowly and test fit OFTEN!

Take your time; you've got all day.

The short sides are easy to keep square, but the long sides are trickier. To make a nice straight edge on them, begin with an opening smaller than you'll need and work to get it square with nice straight sides even though it's too small. Take your time squaring it up at this stage. Then (here's the best trick yet) working with one edge of the opening at a time, use your triangular file to cut small notches all along the edge to the depth that you think you should be cutting. Make the notches a uniform depth and start/ finish in the corners, dividing the edge up into several notches. Then, with your wide flat file, cut until all the notches are gone. This way, your cuts will remain smooth and the edges straight. Be careful in the corners that you're only cutting the edge you're working on and not cutting with the side of the file.

TAKE YOUR TIME; you've got all day.

On FINAL fitting, get the height (top and bottom) right first, and then gradually widen the hole until the switch fits in without rubbing. A slight gap all the way around is better than tight so the buttons don't bind.

All in all, an easy upgrade. Cutting the hole takes some time, but at 2 hours and $45, your time is worth $22.50 an hour, so go for it. If you flub up, there are a ton of members here who still have their old plates; you should be able to find another one cheap."

I bought mine from gmpartsdirect as well and they did come in black, they mark them "no return" since they don't stock the parts normally. Easy upgrade and you'll like the additional info.

How long did It take to come in?

How long did It take to come in?

They seem to take a few days to process the special orders, maybe a week or so?

When I search gmpartsdirect.com with the above parts number, the website says no parts were found matching your search. Do I need to email them to order the 2 parts??

BigBlueLB756 · July 20, 2011

When you go to that website, click on "Chevrolet Parts Catalog", agree to the proceedure, put your part numbers in the blank space, select "Chevrolet/Geo", hit "Search", and you ought to have some results.
