Prius (2004-09) :: Cooling Fans Won't Come On
I 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?
Prius (2004-09) :: When Does HV Battery Cooling Fan Come On
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?

OK, so I have the 100K extended warranty. What can I expect soon after 99K to maybe go out?

I 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:

Prius (2004-09) :: AC Compressor And Condenser Cooling Fan Will Not Come On
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?

I 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.

I'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.
Prius (2004-09) :: Battery Cooling Fan Comes On 1st Time In 56,000 Miles?
First time I've ever noticed it at least. And she's been on 2 huge x-country road trips with much hotter temps than the other day.

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.

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
Prius (2004-09) :: 2005 - Code P0A82 / Battery Cooling Fan Not Coming On
We 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 (2004-09) :: AC Stop Cooling / Little Triangle Warning Turn On And Vehicle No More Moves
Need 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!

I 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.
Prius V :: Using Fan Only With No Heating Or Cooling
I would like to be able to use the fan to bring in outside air with no heating or cooling. What I have been doing is turning the temp setting to Low and controlling the Fan Speed manually.
This seems to work unless the outside temp is too low, then it seems to be heating the air a bit, which I don't work. Is there a different way of doing this? I feel like I am missing something.
Touareg :: 2004 V6 - Cooling Fans Always On
I own a 2004 V6 Touareg as I have been going to the dealership for the last three months now and they cant solve the problem.
Once I start my car in the morning, immediately both cooling fans start running and they wont stop until I shut down the car, it takes them about 10 min to shut down.
Prius (Gen 3) :: Battery Cooling Fan Comes On Way Too Late
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?
Prius (2010-12) :: AC Failure - No Cooling

View 19 RepliesLexus GX 2004-09 :: A/C System Stopped Cooling
Ok, a year or two ago, a small leak in our 04 GX470 prompted me to have an a/c guy recharge system (little did I know how easy it was to do). At the time, he used his blacklight (during the day) and "thought" the condenser might have a leak in it.
Fastforward to now, the system stopped cooling. There isn't any noise from the compressor and the clutch does seem to engage normally.
I went to Autozone and rented the DVD on A/C systems. Using the gauges, I found there was no pressure on the H or L sides. I replaced the condensor (a no brainer ... it even came filled with desiccant/drier though I had to return it since the condenser didn't have the plugs in place so the desiccant/drier would have likely been 'wet' already ... no problem). I noted a very slight grainy, metallic in the system, but not very significant ... I did not flush any hoses, but I did look at all visible hoses for dye stains.
I connected a vacuum pump and kept it a 30mm Hg vacuum for 30 min and rechecked it 30 min later to see that it held the vacuum. The first time, it didn't, so I rechecked my connections and repeated. It seemed to work. I charged the system with 24 oz (27-29 is capacity so I wasn't quite full) and the system was nice and cold.
Unfortunately, cool only lasted 3-1/2 days!
The original condenser plug (for the desiccant reservoir) was plastic or teflon, but the one that came with my replacement was Aluminum. A replacement desiccant bag also came with another plug (a plastic or teflon one), but it seemed to strip so I opted for the metal one anyway (besides, it had two green 'O' rings to just one 'O' ring for the plastic one.
Two days ago, I thought I'd got it to hold the vacuum in the system, recharged it again (I dried the desiccant bag in the oven for 5 hours at 175 deg F to make sure I'd gotten rid of any moisture that had developed).
Dog gone it, it's hot again! Looking at it with my black light at night, I do see dye (I'm using the yellow kind) at the L-side Schrader valve and on the plug to the desiccant compartment, but no where else. Where's the drip line for the condensate so I can check to see if there's a leak in the evaporator?
I tried wrapping some teflon tape around the metal plug for the desiccant/drier, but it still wouldn't hold a vacuum when I tried using the pump tonight.
I have another dessicant/drier bag and plug arriving tomorrow since I'm afraid that it still could just be leaking out the base of the condenser, but I'm not sure.
Prius (Gen 2) :: Cooling System Related Codes Came On
My 2009 has been showing the CEL off and on for a few weeks. Have had it read at auto zone twice, two different codes. Both cooling system related, but not the same. Today I filled the gas tank and it went back off.
Is it possible for the cap to be causing the light, or would the scanners tell that in a code? I just hate to take it to the mechanic when it is running fine and the light is not even staying on.
