The lights are out on the heat/ac panel except the blower speed (high to low) lights are still lit up. It was on heat last time car was drove yesterday and it’s still blowing heat. They have the temperature on driver passenger, but they are not lighting up.

First, we need to check the fuse DSP HMI 10 amp in the fuse panel left of steering column.

Here is a guide to help and the fuse location as well:

If the fuse is good, it looks like the HVAC control module will need to be replaced. I have included the instructions for that as well to help you fix the problem. Check out the images (below). Please let us know what you find. We are interested to see what it is.
