my dash panel and right tail lights are not working.

Most likely you have 2 different problems...check the bulbs in right side tail light if you have not already. The instument cluster commonly need replacement if they are not working.

agree with miles

No brake lights on some vehicles will cause the dash lights to not work, not sure if the Aveo is the same. I agree with the thought you have more then one problem. Goodluck.

it is caused by the malfunction of the splicer 101. be careful because eventually more of the inside and outside lights will malfunction. I also have a 2005 aveo. I have 170,000 miles. chevy knows of this problem bacause of all the complaints they have received but has not felt it a danger to recall this part.
