2006 Rear Fan Blowing red triangle exclamation, red car exclamation, Vsc, circle with !, check engin

welcome!
the fan blowing is usually a sign that the battery is bad. but it could just be clogged. are you too far from luscious garage or art's automotive?
the definitive way to find out what is wrong is to have the trouble codes read.

 

What's wrong with the AC? I also think you have a failed hv battery.

But you also have a failed 3 way coolant valve, that would cause the check engine light to stay on

 

The prius cannot be charged like a regular car. That shop probably put in a foreign oil in the AC compressor. It takes a special ND 11 oil when needed.

If there's a guarantee/warranty on the AC work, it would be good to get it. The damage is probably over $2000 to the AC system.

You may want to have the Toyota dealer address the AC system and Bill it to the shop that ruined it

 

Simple answer to a complex question. Your Hybrid battery is going bad. Soon, the ECU will turn off the hybrid system and the car will experience driving problems as the gas motor has little or no torque. The only fix is to replace the hybrid battery. This has nothing to do with the a/c system. I have had the same problem with my 2006 Prius, so I speak from that experience. Take to the dealer or if you are mechanically inclined you could change the HV battery, either way it has to be changed.

 

You have multiple problems with your car, the hv battery is just one of them.

1. AC SYSTEM
2. 3 way coolant valve
3. Coolant temperature sensor
4. Possible HV battery failure

1 and 4 are pretty expensive to address

 

You can address the hv battery problem, a rebuilt battery will run anywhere from $500 to $2000. Still gotta get the codes read, I didn't see this failure code, just the symptoms

That will get the car running again, but you'll have to eventually address the other issues

 

I didn't see the trouble codes the first time I read your post, just read the part about the rear fan and slow acceleration. I know those two things point to the hybrid battery and maybe the battery ECU. As JC91006 stated, you have multiple problems at the same time and it would probably be best to have the dealer look at it and give you the exact reason for the various trouble codes. Then you could decide which needs fixing now, hybrid battery, and what can wait.

 

absolutely. it's the best way to go, if you can find a good one.

 

Yeah, I've heard the hv battery can actually sustain damage in a hard crash. You just have see the extent of the wreck and hopefully get a good one. Kinda like your brain getting a concussion, a hard hit can scramble things inside and not show any visible damage on the outside.

 

not sure there is one, but $4-800. sounds reasonable for a low mile pack with warranty.

 

no idea. around here, there are a few salvage yards i would stop buy and ask. it has been reported by others that some places put them up for sale.
have you tried ebay?

 

You won't. They (low miles, late model, hasn't been sitting for months, etc for cheap) are more rare than a pink unicorn. Most junkyard dealers have known for years they are worth money.
