I have a 1985 TDT and my cruise control cuts out. If I hold the CC switch it will hold at the desired speed, but as soon as I let go, the CC stops working. I haven't had time to look at the componets of the CC system yet. Could the problem be in the swicth itself? or could it be the amplifier? If anyone has any suggestions of where the best place to start trouble shooting please shoot them my way. Thanks.
