Ever once in a while my blinker on the left side of my 07 will go haywire.The left blinker starts to blink real fast(front works) but now the back ones dont blink at all. The bulbs work and sockets are in good shape, but the problem is intermitent. Please advise. Also whe nI lock my car with the button on the remote the lights dont work on the left side.

Sounds like you are low on blinker fluid.....

All jokes aside it sounds like a ground issue to me. Check all of the grounds around those areas. Also, check for moisture in the housings.
