Speedometer, turn signal, obc, power antenna, all not working

Can someone help me with a problem whereby the speedometer, turn signals, OBC, power antenna, and center check light are not working? The car still starts and the tachometer still work. Also, the 4 way hazard switch works as well. Might it be a bad main computer board in the instrument cluster? A quick reply from anyone out there would be greatly appreciate, especially if you had these problems and solved it!! Thanks....

Try resetting your Service Indicator lights. The batteries on your 'cluster' board might be giving out especially if they have not been 'updated'. Worth a try and it doesn't cost anything to try it. Good luck!!

Thanks for the help.....do you have instructions on how to replace the cluster board battery and where do I go and get the batteries (Radio Shack) and what type of battery do I need?

First, I would try resetting the SI lights (green lights on dash) before I spend $$$ on replacing the cluster board (w/batteries).

Just replacing the batteries may not completely resolve your problem. An 'up-dated' cluster board will be better than the existing unit (especially if you have the original unit..which I doubt).... if this is your problem???

So, again, try resetting and see if it makes any difference. If it does makes a difference but doesn't last very long then I would consider replacing the batteries first before I spend more money on a 'new' one.
