I own one of these vehicles and I too had this problem.
Your best bet is to go to or contact a salvage yard and buy the whole control panel from a wrecked vehicle. Inside of the panel is a circuit board and a usually the control wheels go bad at the point where they contact the control on the circuit board. A beautiful used one cost me $25.00. If you cannot find one you can contact me by e-mail and I will give you my phone number and I will get you one. But I will have to charge you a little extra because I will have to go remove the part myself and send it to you. I do this for alot of people so it is no trouble. Just so you don't think I am trying to scam you. When you call I will give you references to call.
Good Luck Brother and may
God Bless You! James A.
