What dash board lights? The ones for the ac controls? the lights to the dash cluster?Go to a auto parts store get the lights. If they are for the dash cluster you will need to get 10 I believe. you have to completely remove the dash cluster once it is out of the truck all you have to do is turn and pull out the old lights and put the new ones in. If you talking about ac controls there should be a total of 4 same thing once you get the dash apart turn and pull the old ones out and put the new ones in.
Before you do this, make sure that you disconnect the negative cable on your battery and wait about 90 seconds, since you are going to be working around the AIRBAG and could set it off by accident!!!!.
