My inverter over heated. Looked at reservoir for motion of water saw none. Took car to toyota for pump recall. When I got it back I heard the pump. Never heard it before. I don't think it ever worked. & water is flowing in reservor now. Now I am thinking about the HV bat. fan because I never never ever heard it working. When does it come on and how could I test it?

View 8 RepliesWe took our 05 Prius to the mountains on Sunday. Coming down the hill from Lake Tahoe the temp climbed to 98. Suddenly we got the red triangle warning and the Hybrid system warning light. The car ran fine and showed no symptoms of any problems. We took the car to the dealer Monday morning. They Read the code P0A82. They said the Battery cooling fan was not coming on and blamed the problem on dog hair. The warning light was off. The car ran fine going home with no warnings. My questions
1) Can/did the dealer reset the warning light?
2) Is there a way to verify that code P0A82 is a bad cooling fan.
Prius OEM fan control - EAA-PHEV It seems like at least in the Gen II, the battery fan is quite "lazy" and comes on way too late just like most variable speed fans in electronic equipment.
In the Gen III, does the fan have the same problem? If so, is there an easy way to perform the mod that can be easily undone?
How often should the traction battery cooling fan come on? It started to be warmer here in FL, and I hear this fan more often now. I bought my 2011 in December and up until now almost never heard this fan working. Now it comes on at least couple of times a day, mostly under heavy acceleration in Power mode.
View 6 Replies The past week I have noticed my battery cooling fan running constantly on all highway trips - 20 mile one-way trips going 65-70MPH.
The performance of the battery doesn't seem be degraded, but it seems like the battery is hopping more between charging cycle or whatever you would call it , where you watch the instantaneous MPG on the highway drop down for 10 seconds to 40-50, then back up to 60-70.
The car is a 2011 Prius III. It did not run like this earlier in the summer in the same weather conditions, I would hear the fan maybe once every few weeks in hot 90 degree weather. Now I hear it constantly. This is my first summer owning the Prius so this may be normal, but I wanted to double check with you all if this is a sign of premature traction battery death or something.
Some years back my "farm" '05 prius when a host of bells and whistles went off, cooling fan ran more than normal, and I lost power a couple of times. Turned out this farm prius had an accumulation of dirt, dog hair, hay and other debris that needed to be cleaned out. You got me through the whole process, and the car's run fine until.... . Fast forward a couple of years to 200,003 miles. Now the cooling fan is running pretty constantly, the red triangle stays lit, the check engine light comes on, the (!) is on, and the VSC light is on. Haven't hooked it up to check codes, but did check cooling fan and it's clean. Would it possibly possibly better to change the 12 volt battery?
View 19 RepliesMy dad has a 2015 Prius v Three (lowercase v and three, not III). He just hit 7,500 miles. He had the service done at 5k miles. The error message that popped up on the dash today says, "Maintenance required for hybrid battery cooling parts at your dealer"...
View 4 RepliesMy prius 2004 AC not cool what really problem come from ? I didn't do anything with it....
View 4 RepliesI have 05 prius and the cooling fans wont kick on as well as the ac wont work. I have had the cooling fan motors checked they are good. I have changed the 2 cooling fans relays and the cooling fans still wont kick on.
When I bought the car the check engine light was on so I had it scanned and it threw the code P1121 coolant valve control. so I went and bought this part since I heard it was a common problem but haven't got it put on yet. Could this cause the cooling fans to not kick on and ac not to work or is it something else?
OK, so I have the 100K extended warranty. What can I expect soon after 99K to maybe go out?
View 3 RepliesI bought my 2007 with almost 100K miles on it back in November. It's been a great car, and I had various maintenance done to it and did some myself. Looks like there's a problem with the A/C -- it's just not cooling the air. Yesterday was the first day in the sixties here in NJ, and the A/C just wasn't what an A/C is supposed to do.
The car was maintained at a dealership exclusively. Here's the entry about the A/C:
05/29/2012 93,478 AIR COND. INSPECT
I have an 05 Prius with 53k miles and the ac just recently stopped working. The blower fan still comes on, but neither the compressor nor condenser cooling fan will come on. I've checked the fuses and relays, and they check out ok. I'm hoping there may be one I missed? It just stopped working with no warning signs. What could be causing this? If the compressor was bad, the condenser fan would still work, right? I'm fearing it's the ac inverter. Do the symptoms match?
View 9 RepliesJust read a post about this, I would like to check mine and see if it needs cleaning.
View 2 RepliesI have a 2008 Touring. The air has always been ice cold, even yesterday. On my commute this morning I noticed that the air was not cold at all for the first time ever. The outside temp said it was 77. I changed the temp, turned it off, etc but nothing changed. I just had it at the Toyota dealer 2 days getting the oil changed.
View 2 RepliesI'm coming up on my 120K service and will be replacing the spark plugs, PCV valve and I wanted to exchange the engine coolant (SLL pink stuff) for the engine. I replaced that stuff on the inverter side when they replaced the heater at a TBS recall.
I have a haynes manual and have searched on prius chat, but just cannot find specific instructions about this. On my '65 Ford mustang, there was a stop cock that I would just open or I would pull the lower radiator hose. To flush I would just pull the thermostat and run water through the system to clean then refill with antifreeze and water. I think that it will take about 6 quarts so I ave 2 gallons of the SLL pink stuff.
I had my AC charged and belt replaced after this all is done I noticed the cooling fan likes to run a bunch now - its 80's outside and the cooling fan runs all the time.
View 12 Replies I have a 2007 Prius, and bought it used about 4 months ago. I have not had any issues with it until last night. Last night I was driving home and the red triangle with the “ ! “ in the middle and check engine light came on. The car seems to be running fine, but it scared me to see the lights come on...so this morning I called my local Toyota dealership.
NOTE: I recently went to them for an oil change and they informed me that I had three recalls on my vehicle that needed replacing, but I did not get them replaced because I was told it would take 5-6 hrs (which I didn’t have at the time).
Anyway, they told me that it would cost $70 to have the codes read...and that did not include parts that may need replaced... I thought that sounded a little high for just having the codes read so I went to my local Autozone and they gave me this code:
P0A93 - Inverter Cooling System Performance
I tried to turn on my car this morning, but the "Ready" sign didn't go on. The whole display is black. "Check Engine" sign blinked briefly. Battery display shows the battery is "green". Everything else works - cd/radio/bluetooth, etc. As I tried to start it, the screen showed that the engine briefly charged the Prius battery, then it was all quite. I tried to wait and restart a few times, but still the display was all black and no "ready" sign. I WAS able to still move the car, but I didn't chance to drive it out of the garage. I just had it serviced (oil/fluid change). Small battery was replaced in July.
View 19 RepliesNeed to solve the problem of my Toyota Prius car in 2008. The car is cold while working well for a maximum time of 1 hour, the first symptom is to stop the air conditioner to cool, then turn on the light triangle warning, after driving a little longer for the vehicle and no more moves. If you wait until the vehicle returns to work for a few minutes to cool, then everything fails again with the same symptoms. And you change the battery 12 Volt, and you change the water pump hybrid system and I can not solve!
View 3 RepliesI am having issues with my air conditioning on the 05 prius. For some reason when I leave to go somewhere its fine, but if I stop for long periods of the time the a/c stops cooling, the fan is still blowing. Once i take off it cools somewhat better but still not cold as it should be.
I have already had the car checked for DTCs and there are none, plus I had the a/c vacuumed down and recharged to factory specs, it still has the same problem.
