Instrument cluster and tail lights went out. checked all fuses, replaced bulbs. what naxt

it all points to a fault with a common ground. Find earthing points

This may sound confusing, so here goes.
Normally I would say check the turn signal switch because for decades the brake light switch power went thru the turn signal switch.
But in your case, its more complicated.
The wiring diagram looks like you have a wire from the brake switch and another from the turn signal that joins inside the right and left rear tail lamp assembly. There are also fuses in the rear fuse box including one for just the brake lights. So its possible that fuse is dead and yet the turn signals would work.
You may have to get a book with the wiring diagrams to trace the circuits.

Duplicate question.

Yes, the problem is the turn signal flasher is defective. You can has two flasher relays. One for the turn signals and one for the hazard lights. That is why the hazard lights flash and the turn signals do not. Replace the turn signal flasher relay located on the drivers side of the steering column, mounted behind the instrument cluster in the convenience center. They are both mounted in the same location so turn on the hazard lights and the one that you put your finger on that is not clicking is the turn signal relay.

I could not tell you how many times people have brought their cars into my shop and tell me that they had already checked all fues and they are OK, then I check the car and find a blown fuse or a fuse that is completely missing.

Your dash (Instrument Cluster) illumination lights are powered by the "PARK LP" fuse in the underhood fuse panel - it is fuse number 37 and should be a 20 Amp fuse. If this fuse is blown, your Park lights on the exterior of the car will also not be working. If they are working and your dash lights are not, then the problem is probably in your headlamp switch.

Your Brake lights are powered by the "STOP LAMP" fuse in the instrument panel (IP) fuse block it is a 15 Amp fuse.

Your Hazzard lights are powered by the "HAZZARD" fuse in the (IP) also a 15 Ap fuse.

If both of these fuses are good, then the most likely problem with your brake and hazzard lamps is the multifunction (Turn Signal) switch.

What any of the above has to do with replacing your window regulators remains a mystery.

if its not the fuse then you have a bad headlight switch

Brake light switch, located on upper brake pedal should be checked, that is most likely your brake light issue, but U say tail lights aren't working, but running lights do, tail lights and running lights I would consider to be the same, so can u clarify that for me? Let me know how the u do w/ brake light switch, and if u have issue w/ tail lights?

Your Hazard fuse is blown.
Hazard fuse has the instrument gauges on it in addition to the turn and brake lights.

When one of my brake lights went on my 07 Caravan it when short for a time and took out this fuse.
