Blinker problems 1987 chevy silverado?

When i turn on my right blinker everything works perfect. Im confused i looked at all the bulbs and all seem good. I looked at the license plate light and it looks like a new license plate light is installed. Any ideas or hints would be much appreciated thanks.2. JKSTools Says: Check the ground for the left tail light. It sounds like the turn signal is trying to ground through the other bulbs. If the ground appears to be tight, take it off and clean it and the surface it is attached to. There might be rust or corrosion keeping it from getting a good ground.3. don r Says: Replace the light relay that controls the brake light. This has been a common problem for GM.
