2009 Toyota Camry with the 4 cylinder. This is not my car but the air conditioning and heat were not blowing any air at all. I went and found that the blower motor fuse was blown and since this is one large fuse connected to other fuses I went online and purchased the whole fuse. The fuse is secured by a bolt and so when the part came in and I went ahead and tried to install it. I was unbolting the single bolt that secures it down and the other end of my ratchet hit the battery and created a spark. From that point on basically half the car stopped working. No radio lights, no power windows, cannot shift gears without manually pressing the release, no power seats, no automatic headlights, and I am sure there are other things that are not working. Oddly enough I can still start the car, gauges work, and even the headlights work but only on manual. I have tried to disconnect the battery and reconnect. I have also checked pretty much all of the fuses with no luck. Any ideas what I must have done.
