However, the front turn signals stay full on solid. No blinking, just both solid. Switching the wires back makes no difference. Head lights and tail lights do work.

Any ideas?

Villages Guy, I am guessing you are a DYI person, so am I, my background is a retired professional electrical engineer with a lot of automotive experience. If you get the run around from the dealer (since you worked on the golf cart), I may be able to help.
First try reversing what you did initially. If you still have non working turn signals (not reversed), then as previously stated, you probably damaged the turn signal module and you will need to get a new one. With any luck it will come with a wiring diagram, and I could be of assistance if you need help.

Hope this helps.
