One long bolt at the top - requires a 7mm socket to remove the bolt. The light housing will pry out with a screw driver. There are three ball and socket type connectors that hold the housing in and I just pryed off the plastic housing carefully and "balls" pop out of the sockets. Finally, I was replacing the faded plastic housing and it came with a new wiring harness. It's impossible to reach the connector to use the new wiring harness that comes with the new plastic light housing. So just use the existing wiring harness with the new light assembly.

likely not, but change /check anyhow....If problem persists, likely you will need to change the module that controls directionals (usually under dash to the right of steering column)

Normally when this happens you have a blown bulb on either the front or rear the fast blink is because with only one bulb working the flasher clicks it faster less of a load means faster blink.

Hello. This happens when one of the bulbs is starting to go bad. pull all of the turn signal bulbs and look carefully at each one. you will find one with the filaments crossed. Replace that one. J.
