Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

In your under hood fuse panel locate the over voltage protection relay and see if the fuse is blown in the relay.If it is blown replace it and see if it then operates properly from there.If this is or was checked already and found to be o.k. let me know so we can continue.
