My uncle took battery out, then put it back in. Everything works except right side of turn signals. However it has rained a bunch and my mirror turn signal got water in it. Could that make all the right side bad? I checked fuses and bulbs in front and back, everything good.

Hello,

It does sound like you have got a short to ground somewhere in the harness. I have included in the diagrams below the exterior lights wiring diagrams for your vehicle. Check them over and let us know what you find out.

Thanks,
Alex

Thank you. I have used Google to teach me how to take back and front lights out and see where fuse boxes were. I will try this tomorrow.
