My brake lights and rear turn signals are out.

What is your question?

What could be causing this? My 4-ways don't blink in the rear either. The issue started a few months ago with me getting a message to check my RR Signal Light. Changed the bulb and it was okay for a day or two, then started getting the message again. Got some bulb grease and used that to improve the connection. That worked for several weeks. Now, both rear signals are out, along with the brake lights and the 4-ways in the back. Front signals blink rapidly as well as front 4-ways.

What makes this problem better or worse?

All the time
