Hello, welcome to Just Answer/Pearl. My name is Mike, I willdo my very best to assist you with your question today.
Are there any warning lights coming on at all/
Also any symptoms leading up to this issue?
Yes, all the warning lights work. It's the illumination of all the switches, the outside temperature gauge and the ventilators that's the problem.
What is an instant cluster? What do I replace?
Will replacing the instrument cluster make all the other lights in the electric window switches etc. in the central console work?
I have now replaced the instrument cluster from an identical donor vehicle which was not displaying the same problem but my lights still do not work.
No, sorry, I don't.
