I just purchased a 2000 coupe with 38K miles. I cannot get any of the DIC control buttons to function. I have odometer only on the DIC after start up. What am I doing wrong, or not doing that I should be? These buttons should work anytime the key is on shouldn't they?

 

They take some pressure to get them to work, but just not too much. They "DIC" switch might be unpluged?

 

I have pressed pretty firmly. Is there a DIC switch? if so where? Where would it be unplugged?

 

Yes, they should work anytime the car is running or the key is in the on position. Perhaps the DIC switch is bad and needs replacement. The switch is located to the right of the steering wheel on the dash - has a series of about five buttons.

 

The troubleshooting procedure just suggests changing the DIC switch. If it's plugged in properly and the connectors are clean and tight, looks like its a bad switch.

 

It plugs into the rear of the IP Cluster, with the connector facing forward so pushing on it will do nothing.

 

Hmmmm....any ideas on how I reach the back of the switch assy to check the connector? Anyone know if there is a fuse that controls that switch?

 

I have had this problem for quite awhile on my 99 coupe. It starts with the DIC occasionally auto scrolling options button is being pushed .. eventually the buttons stop workiing totally. Replaced DIC switchs. Nope. Posted this couple years ago and since I was one of the first with this problem; was pretty much treated like an idiot.. except for a couple good guys.
I have seen a couple posts where the problem was solved by replacing the IPC.

 

The guide suggests a switch change first and then if that fails, an IPC change. Hopefully the OPs problem is a switch.

 

Heres the procedure to replace the DIC switch

Thanks so much DeeGee for the very detailed help. I have my work cut out for me, but I will follow your recomendations in order. Thanks also to Prymtime for your links andhelp. I hope you finally got resolution to your issues.??
This C5 is a whole new adventure in driving and repairs. I will likely let a dealer fix this DIC issue, but I want to know what should be done before I let them. I bought 100% mechanical coverage that covers me for another 60K miles when i bought the car from a dealer just in case this type of thing happened to an 11 year old car. I think it will pay off.
Thanks again, and I will report back when done.

 

Very smart with the extra coverage.Also good to know what they need to check beforehand because odds are... you will have to tell them!

 

Good thinking. If I had warranty cover I'd let the dealer fix this one
