Radio problem 94 Cutless Ciera
 

I have a 94 Cutless Ciera that has a kind of odd radio problem. It had a power antenna that stopped working, which would cause the radio to not come on. I had been told that disconnecting the antenna motor would fix the problem. So I had the mechanic to do that and what he did was cut the wire to the sensor to if it was up. This didn’t fix it so I decided to cut the power wire. That did fix the radio problem for some time till it randomly stopped working again, but sometimes when turning the car on it will work again. Recently it seems that it doesn’t even work then. So I was wondering if anyone had any suggestions.
