Thanks to all that answered my taillight problem. I have one more question about one of the answers. If my signal switch was bad, why does it still work on the left front? Are they all on separate circuits? The brake switch is new. It went out few weeks ago. Any more help thanks again.

The first thing you need to check is your ground connections on each light assembly. Check the connector where it grounds to the body. Make sure it has good and bare metal and a tight connection.
Check the bulb socket for any corrosion or oxidation. If there is any, clean it up.
I have to assume that your brake light switch had to be replaced. If so, and you replaced it, do both brake lights now work? If they do, but your turn signal does not work on the rears, then yes, it will probably be the turn signal switch.
The brake light wiring leaves the brake switch (mounted on the brake pedal) and goes through the turn signal switch assembly. From there they go to the rear tail light assemblies.
This is just a basic description. If you search the forum here, there is probably a wiring diagram that will go into more details, but honestly it does sound like the switch (if all grounds are good).
