Found the problem. Rain gutter below the windshield and above the battery compartment is made from several connecting pieces. One of the connections or seams is directly above the OVP. During the troubleshooting I removed the OVP and found it full of water that had dripped from the ill fitting seam. Replaced the OVP, attached a plastic bag (raincoat) over it and applied windshield sealant over the seam. I've heard of many different problem caused by a bad OVP. Don't ever dismiss it when electrical problems occur. I'm going there first for any malfunction......maybe even a flat tire!
All the best to everyone.
