986 Boxster S instrument cluster not working
I have got a problem with 986 Boxster S instrument cluster not working properly;
- the analog speedo and rev counter do not move, both gauges do not move at all - mileage, etc. on the lcd screen at the bottom of speedo do not illuminate All other instruments function normally; fuel gauge, indicators, etc. all ok. I connected with Durametric, and I checked the following - engine rpm shows (i.e., rpm signal comes from engine dme) - in the activations menu, I can activate; rpm --->8000 ok speedometer ---> full speed ok However, I cannot activate lcd screen all pixels, the lcd part stays entirely dark, nothing shows. Please any ideas where to start diagnostics? Cheers!

I have a little experience with the clusters based on swapping a Carrera cluster into my car. I prepared a document with some notes and pictures. If you send me a PM with your e-mail address, I'll forward it to you.
I don't have any experience with the problem you are experiencing. Have you removed the cluster for any reason such as to replace a light bulb? If you removed it, perhaps you did not seat one of the connectors correctly when you reinstalled it. If this sounds like a possibility, I suggest you remove and reinstall it. Wayne has published some good instructions here: Pelican Technical Article: Boxster 996 Gauge Cluster Upgrade - 986 Boxster (1997-04) - If it was just one lcd not illuminating, I would suspect a failed bulb, but it seems like a big coincidence that all of them would burn out at the same time. Perhaps there is a fuse that powers part of the cluster that is out. I think you need to check B1, B10 (both 15 amp), and E1 (7.5 amp). However, since you have a car built for Sweden your fuse layout may be different. So check the chart under your fuse cover. Another remote possibility is a fault with your ignition switch. Good luck with trouble shooting. Last edited by KevinH1990; 06-18-2013 at 03:34 PM.. |

Was this problem ever resolved? I have almost exactly the same problem at the moment with my 986.

Mr rev counter is completely erratic and has a mind of its own. I have been told the coil packs breaking down could cause this, any hep would be appreciated. Dean
