Instrument cluster went blank 8 months ago and shop replaced "computer driver" with used unit. This worked for about 6 months, then problem started again and at first I could hit the dash and display would re-appear, but now dash is blank and hitting no longer works. Ideas?

Maybe the used unit was defective? hitting it to have it turn back on leads me to believe something was loose inside of it to begin with.

Used unit worked fine for 6 months, then began to fail same as old one so I was wondering if some other bad part might be eating these up?

It's a common problem so it was probably just the used part's time to die. You can always check and see if the plug got loose tho.

Make sure your fuses are the correct size. Too big would cause extra heat and more than needed current. I have an extra cluster if you need.

Wrong size fuse just won't blow when it's supposed to.

Not sure what the computer driver is. I sent you a PM.

The problem is likely cold flow solder joints or contacts that have worn where the display module contacts the board. It can be fixed by re-flowing the solder.

Excellent information. I have seen similar problems on other makes and this sure fits the pattern. Thanks very much.

Thanks, read your PM and price is very reasonable. Forum would not allow me to use PM system cause I'm a newbie. I will pull my cluster within a week or so and let you know if I need yours. Shipping would be to 37033.
