i've posted about the instrument panel buttons working then not working and now stuck on service soon. started last year with code qc424111 which nobody in the world knows what it is. I've seen several you-tube vids about this problem but no fix. seems like the fix is a salvage instrument panel. I really do not want to go this route but I can't find any fix to this problem. that's the only thing that does not work right on my Vette and it bugs the hell out of me. gauges work fine. i'v called about half dozen places that advertise about this problem and some say we might be able to fix and some say can't fix it couple said to send it in and they will see if they can fix it. none of this sounds good. I've found one from a 98 and the owner said it worked good when removed. 150 to me and the mileage was 105k. my 97 has 50k so after the 150 then there is the price and hassle of finding someone to reset it to my mileage. what a can of worms. I hate to get this IPC from his 98 and then i hope it works. watched a vid where a fella resoldered all the spots on his and and it did not help. I did resolder the HVAC dim light problem and it worked well. saw where someone replaced the DIC buttons and did not help. if anybody has repaired theirs and knows the trick I would appreciate a little coaching. not a whole lot of info out there about this problem. thanks

 

My ‘99’s has been weirding for some time now. From my searches of this and other forums and websites there seems to be three primary possibilities:
1) replacement instrument panel
2) ignition switch
3) the ground point at the bottom of the driver’s A pillar (forget its number at the moment)
When I find the time and weather I’ve got to change the ignition switch, and will see if that helps mine, then will chase the ground.

 

i'm in the same boat redzg. lt's what i call the driving season right now and i don't want to tear anything apart right now. my grounds look good as i think this 97 was garage kept all it's life. i'll check them anyway. don't have any problems with the ign. switch but when running out of options i'll check that too. instrument panel in my opinion is a coin toss. got a couple more repair people to check but nothing solid. thank for the reply.

 

Not sure I understand your expectations. There is no DTC qc424111, so yeah....no one can help you with that.

- You have a 98 IPC that is available to you, but you don't want the hassle of having the mileage updated. Not even willing to purchase for use at a later date.

- It's "driving season" so you do not want to tear apart the dash, and would rather drive around with a service message staring you in the face.

- Limited troubleshooting has been done because you would need access to the IPC connector at a minimum.

What advice are you looking for here?

 

i'm looking to see if anyone has this problem solved and if so how. yes I would rather enjoy another summer, without the car sitting waiting for a possible repair with my dash apart. I can get by without the service message bothering me. yes there is limited troubleshooting because there does not seem to be any. mileage update would be a Hassle because I don't know how to start that. 98 is probably still available. mine took a dump at 50k,hope that one works at 100k plus. was looking to see if anyone has this problem and what the fix was. the you-tube attempted repairs I watched did not solve the problem. this seems to be somewhat of a problem in the c5. I'll probably have to give up and buy the 98 instrument cluster and use it for a winter project and hope for the best. thanks lucky for the reply.

So are the gauges working? Do you have a service manual?

 

yes gauges work, thankfully. i always liked to check gauges and other things through the DIC buttons but thats not happening now. i have not checked with a service manual yet but i doubt it has anything about getting in there and repairing the electronic stuff and ipc. i've had a couple other c5 people on other forums ask if i had a fix yet as they have the same problem. saw a couple vids on how to remove the panel for light replacement and some removed the ipc on other video's but no definite fix. it kinda looks like i'll have to suck it up and do what i don't like to do and thats buy used electronic equipment and being about 27 years old at that. i'll think about it for a couple more days then make a decision. also there are quite a few of these panels on e-bay for about the same price with the old runs good and good condition tag. thanks again for advice lucky

 

My path forward be fore changing the IPC would be:

- Check the service manual for analogous troubleshooting

-Inspect IPC PCB for any obvious signs of damage, corrosion, electromigration, cold solder/cracking (with magnification)

- Use schematics / connector-end-view to confirm all wiring is good at IPC connector

 

ok here is the latest. e-mailed repair service called Batee instrument repair service. this is what they said about our c5 Vette panel. GM cancelled all parts and contracts and there are no parts left to repair these instrument panels. with that being said I went ahead and bought the 98 panel I talked about in my post. it's either a salvaged panel or nothing. this will be a winter project as I need a little time off from the balancer repair and small coolant leak fix. thanks to everybody for their replies and I will continue to check into this as you never know who might know more on this.

i'm gonna write down some of the things i'll check for this winter project. grounds under door jams, other grounds have been checked and are good. when I get into the dash i'll unplug the connections in the panel and clean them and see if that solves the problem. same with the DIC buttons panel. I thought about switching the small board that houses the odometer onto my panel and see if that's the problem. not sure about that move because of my lack of experience. my only experience was repairing the HVAC board because of the dim light problem. some soldering but pretty easy. would really like to keep my 50k. when I install the 98 panel I would like to check it out before I assemble everything back together. is that possible? 98 panel should be here next week. checked another outfit that said they repair instrument panels and they said not the c5 Corvette. saw an older post that shows the removal of the panel and covers. I'll have to use that as a reference. I think I saw one of your replies in that one. anyway I got the parts now and hope for the best. Denny
