You will have to find the control module to see what series you have, my control module is mounted under the dash, I can access by removing the dash portion that has the radio mounted in it.
Mine has 3 or 4 wiring harnesses attached to it, they do sometimes get a little corrosion, try unplugging and plugging back in. They also have some tests you can perform on the control module, the troubleshooting guide will have the info.
I'd start there.
