I don't know if this is related but I'm having some electrical issues with my van. It started with the fob not starting, had to jiggle it and then it would start. Thought batteries, changed them and haven't had that issue since, but the driver door no longer turns on some light or kills radio when opened. Bas, esp, and traction control light come on but normally I shut car off and restart and they go out. This is random but happens. Now my left rear brake and turn signal will work for about 10 seconds then I get a fast blinker like the bulb is burned out but it isn't. Is all this related? Could my computer be starting to go?
