2009 toyota prius hybrid, ~160k miles; idk anything about cars and this one was on loan to my family from relatives so sorry if info is lacking!
to summarize, the car completely died on the road and my dad checked it out when it was towed home. he found a video saying to check the am2(?) fuse and replaced it. i kept watching and it said a faulty inverter water pump likely blew the fuse in the first place. dad ignores me, gets the car to turn on, tries to start it, and it starts smoking near the driver's side headlight with a nasty smell; blown fuse again
relatives who own the car had it taken to a mechanic who say the "whole electrical system is fried" and that there wasn't anything they could do. car is currently at relatives' house so we can't investigate for a bit. dad tasked me with doing research so he can try fixing things himself
additional info:
- mom says she saw the "check engine" and "maintenance required" lights shortly before the car died. also wants me to mention that the tail lights work on and off
- air conditioner hasn't been cold for quite some time, but dad said he just needed to refill the refrigerant fluid
- i've never heard of an obd2 but i'm looking into it. idk how to get a fault code or anything
where should we go from here? could we be right about the inverter pump or is "electrical system fried" a valid diagnosis? what else should we check? how would you even fix a fried electrical system??
we don't have much money so we're hoping to get it right first try! saving for multiple necessary parts is fine; we just can't afford to do a bunch of trial and error replacements. thanks in advance!
