you may have wires crossed if some one has installed a new radio system recentley My Villager did this a couple of years ago. After countless hours in the shop it ended up being the rear taillight. The lead contacts on the bulbs were touching one another and shorting the system.
If the brake lights stay on that probably means the switch on the brake pedal that activates them is defective.
This is usually cause by a stuck brake light switch on the brake pedal. Replace it.
"Stuck" brake lights indicate that the brake light switch on the brake pedal is broken. It should be replaced.
Brake light switch needs adjusting or replacing. It is too sensitive.
I have a 98 Villager and I had the same problem. I found that the brake light switch at the brake pedal needed adjusting. Just loosen the lock nut and adjust the switch so that the brake lights do not stay on but only come on when the brakes are applied, then tighten the locknut. Worked for me. Hope this helps.
On the brake pedal assembly.

I would check the rear bulbs. I just had this issue and it ended up my brother had used the wrong bulb, and odd enough it caused the brake lights to stay on with headlights. When headlights were not on and you applied the brakes the dash would light and brake lights worked. Strange, HUH? I must admit before this revelation, I replaced headlight switch and brake switch, with no avail.
Not only the brake switch but also there are 2 plastic buttons that depress the switches sometimes these wear out and need replaced ,I couldn't find these so I improvised .
Just normal DOT3 brake fluid.
It is self-adjusting, normally.
