If you are trying to save money, I would recommend resoldering all the joints on the circuits involved, it's an easy and enjoyable task to do.
I had a simiar problem with my 94 plymouth acclaim, resoldering the cluster fixed it right away. I'm still having the same problem with my curise control computer in my 190E, after I resolder it, it works for 15 minutes but that's because of the brake light bulbs
I don't use CC anyway
Might want to try it.
I fixed all the electrical problems in my car this way.
