Instrument cluster not working

Hi Abumayar,

Can you elaborate a little more? Do you mean the brake lights?

Thank you, That would be the instrument cluster here. Being this is intermittent I would suspect either a loose connector or a wire that is failing. Do you notice any pattern in the failures? Such as it stops working after a hard bump or during a cold day? Or perhaps it stops working and a hard slap to the dash makes it work again?
Are there any other items that stop working at the same time?

Well that does help but not in a good way. It suggests there is a leak that is letting moisture into the system. For that a good inspection for water intrusion would be a good step. The other item related to that would be does it start working after a rain without moving/driving the vehicle? Does it have a sunroof?

That all sounds like you have a water intrusion issue. Basically there is a leak that is letting water into the vehicle and it is getting into the electronics. The usual culprits are poor windshield sealant or the sunroof drains getting plugged and the water then drains into places it shouldn't. The only real repair will be finding the leak(s), repairing them and probably replacing the module(s) that water damaged. The only way to find the leaks is to remove the trim panels inside and look for signs of water. Is this a US spec vehicle with the steering wheel on the left side or a right hand drive version?

Have you tried removing the cluster and checking the connection at the rear of the cluster, sometimes just taking the connector off and reinstalling it can fix a bad connection. Here is a video of the job being done on a similar car.

Please run down this guide and report back.

HMM, I thought all the Japanese models were right hand drive. Either way I would still look far water entry, especially as rainfall seems to change the unit from not working to working and the reverse as well.
