No rpm, speedometer, odometer, gear indicator and struggles to get engaged into first gear. It is intermittent. I changed the ignition switch which worked for a minute.

I would check the fuses and if they are okay it sounds like the IPC needs to be replaced, here is a video of the job being done on a similar vehicle. This guide can help you check the fuses:

You can get a preprogrammed unit by searching Google or Ebay. To confirm the issue, check the grounds and power supply to the cluster, here is a guide to help:

You might want to try removing the cluster wiring connector and reinstalling it to see if it is a bad connection. Here as the cluster wiring diagram so you can see how the system works Check out the images (below). Please let us know what happens.
