Got autostart installed everything was fine until a day later I wake up and autostart the car, a 98 lexus gs400,
Go to unlock the doors nothing, no response, so here's what's happening literally overnight.

Key fob does not lock/unlock the doors
Gas gauge flashing
Telescoping wheel doesent work
No heat/ac
Alarm goes off when u open the trunk/hood
Main window switch only opens drivers side
Car won't shift into drive or anything else without override
Power mode/snow does not work
I was told it's my door ecu but which one? Every door has a ecu I'm confused as why it just so happened overnight when I gir autostart installed, I'm making an appointment to get it taken out ASAP..

All of these things don't happen over night. Therefore, I feel there is an issue with the system that was installed. It is difficult for me to pinpoint things because there are so many different types and brands when it comes to these things, and they are all designed differently and connect differently. When do you have it scheduled to be checked? My guess is they have changed something with the ignition itself.

He has something crossed that is causing the battery to go dead. If he can't fix it, I would make him remove it and give you your money back.
