No power to front left signal
I remember last year I was able to get the front left signal light to work for a bit after disconnecting the battery. If it stopped I would again disconnect the battery and so on.. I checked all fuses, which were fine and I checked for power at the lamp harness and got nothing. Battery disconnect isn't working anymore. Any Ideas? (Brand new proper bulb, contacts in the socket are clean and making good contact.)
Also the driver seat likes to start massaging my back whenever it feels like it,
.
Would be great to have some light shed on these issues.
Thanks in advance..

This is a troubleshooting Catch-22: You need to measure the voltage if the bulb is not working, but you can only measure the operating voltage if the bulb is working (since the SAM quits powering the bulb if it detects too much or too little current is being drawn).
I suggest you inspect the quality of the electrical connection between the bulb and its socket. Clean as necessary.

Thanks, but I stated the contacts are clean and making good connection. I removed all the front computers, removed the covers off of them and inspected for water damage but the boards look like brand new. It must be either a bad relay or ground somewhere..

The signal lamp is powered from the left-front SAM. You may find the wiring diagrams for the W215 indispensible, and they are a free program for download: W215 ETM 64. While viewing a diagram use the mouse to pan in all directions and use the page up/page down keys to zoom in and out.
