Dear Mr. Boxer Dog. You look kind of like my dog.
I suspect that the car was left on - as people sometimes do with Prius cars since you can't hear it run. In any case, on Sunday I went out to start it and it was dead. We jump started the battery - directly to the battery in the back, not the little jump-start thing on the fuse box in the front. It started up ok but I did'n't drive it anywhere. I just turned it off a few minutes after we started it up.
So this morning when I went out to go to work I realized that it was not right. I could unlock the door with the remote, but the signal was weak. then the car started also with the remote, but only the dashboard lights flashed and flashed - all of them, it was kind of scary!. So I turned it off, and it hasn't started since. We tried to jump it again, didn't work. I went to Toyota and bought a new 12 v battery, didn't work. My husband looked at the fuse, it seemed to be intact, but tonight we couldn't replace it. He thought it looked ok though.
It's a 2005 Prius with 150K miles on it, I had never replaced the 12 v battery yet, so it made sense to me that it would die. But now, even with the new one, we don't get any dashboard lights, dome light, beeping when the door is open, anything. No response at all.
HOpe you can help!
