we had the same things on ours - the brake shoes on the back are stuck - you will need to get it towed to a shop, the wheel pulled and the brakes adjusted
I have a 2000 Dodge Grand Caravan with 135,000 miles. It hasn't been driven in well over 2+ months. Recently I tried driving it to move it, but as I was backing out of my drive way I noticed that the rear wheels were not moving. What's wrong and how can it be fixed?
I tried going back and forth and the rear wheel on the passenger side unlocked, but the wheel on the driver's side remains stuck.
rear brakes are stuck, try going back and forth several times to break it free, Is your emergency brake on? If going back and forth does not help, you need to take the drums off and re-adjust the brakes, this can be done without taking the drums off but you need to see if anything else is wrong with it.
