I bought a replacement camera from amazon for less than $40. I installed it and it works beautifully. After I installed it the button to lower the gate no longer worked. I then removed the panel and checked the switch with an ohm meter. The switch worked fine. I then jumpered the connector and the lower gate circuit worked fine. I checked the contacts in the female part of the connector and found that they were too large. I took a pick and forced them to be smaller and now the lower switch works perfectly.
