What do you do if the dealer took my car back for no reason and wont ive me back my Dow paymenT?

A dealer cannot just "take your car back" which is quite simply, "REPOSSESSING THE VEHICLE" for no reason. There would have to be some kind of violation of the terms of sale/payment for them to repossess it, & they would still have to file some kind of legal action or go to a COURT and obtain approval and paperwork authorizing them to repossess the vehicle.

If this had been the case, you would have been served notice that you had to appear in court to admit/dispute the dealer's claim, and would have been given the opportunity at that time to work out an agreement with the dealer over the dispute, & the court would have sanctioned either the agreement between you & the dealer, or ruled in favor of you or the dealer. Any way that the court ruled would have been entered as a court ordered judgment and entered in the court records and both parties to that action would have been given a written copy of the ruling.

If none of this occurred, and the dealer cannot show written proof that he obtained the legal right to repossess your car, quite simply, the dealer has STOLEN your car. If that is the case, call your local Police Department and file a stolen car report, and give them all the information as to where the vehicle was taken from and if you have spoken to the dealer and know for a fact that they have the car (as in they admitted to you that they took the car) and the car's location.
