Prius (2004-09) :: AC Only Blow Cold Air If Temp Is Set At MAX Cold

My 2005 Prius is having a problem with the AC. It will only blow cold air if the temp is set at MAX COLD. Any other temp setting and it will blow hot air. Really hot air. It makes no difference what the outside or inside temps are. Is there a simple fix for this? I can control the AC by setting it on Max Cold and changing the fan speed, but I would like for it to work on the auto setting the way it is supposed to.

Prius (Gen 3) :: Car Won't Go In Ready Mode In Cold

As the weather has gotten colder (32F +/-2F in the morning), my car is not going into ready mode as consistently as it was in warmer months. I also notice that I have a much better chance of success of going into ready mode if I let the car "pressurize" for about 10 seconds prior to pressing the power button (pressurizing = whatever is going on when you open the driver door and you hear the electric noise of something working (brake pressurization) in the front of the car that runs for about 10 seconds).

Prius (2004-09) :: AC Not Shooting Out Hot / Cold Air

So my wife was just out earlier today when she complained that her A/C wasn't working. So I did some research and got some A/C Recharge for it. Still nothing. It's not shooting out hot/cold air. I cannot even feel or hear the A/C starting at all.

Prius C :: How To Turn Off All Heat And Cold A/C

I have a Prius C 2013. In my old car, I could turn off all heat and cold A/C, and it can guarantee that heater and a/c compressor are not running. But with Prius, I turned off Auto, heat and cold A/C, and I can still feel warm air coming out the the vent when it is running on the highway. Why? How to solve it? I am just trying to suck air from outside into the cabin without wasting fuel on heat or cold a/c. I am trying to get higher MPG.

Prius (Gen 2) :: When Temperature Increased Slightly AC Gives Hot Air Instead Of Cold

I have a 2005 Prius that's got a strange temperature control problem. When the temperature is set to MAX COLD, then it blows cold air as expected. As soon as the temperature is increased slightly (say to 65 degrees) the air gets really hot - as if it is already on MAX HOT. Between 65 and MAX HOT, the air stays consistently very hot.

Prius (Gen 3) :: Engine Revving Up In Cold Weather

I was heading home last night from work and noticed something odd. It was the first pretty cold night that we have had around 20-25 deg. and I took off from the parking lot like normal.

When I got to the first stop light about a mile down the road I heard what sounded like the engine revving up right when I took my foot off the gas pedal. It did this as I coasted to the stop light. It also did it again at the next stop light just up the street. I thought maybe it was the heater blower, but It really sounded and felt like the engine revving. The car did not accelerate or anything, is this part of the warm up or normal? I also have the lower grill blocked but I don't see how that would make any difference.

Prius (Gen 1) :: Steering Shaking Only At Low Speed When Cold

I purchased a second hand 2000 Prius for my wife about a year ago and the car has been awesome. A few months ago she started experiencing a steering vibration only at low speed when cold and steering wheel turned sharply.
It got worse till you could feel a slight vibration when even going straight, I tried to scan the OBDII for faults but my scanner would not even work on the Prius.

I search online and bought a U380 OBDII scanner but since it would take a while to get to me I decided to disconnect the 12v to reset the computer (and fix my map lights while disconnected) when I reconnected the 12v the car started ran for about 10 seconds then cut out with the red triangle showing. I thought maybe I had done something wrong and the immobilizer had cut the engine, went inside to check my manual I had bought(cd version) on my computer and google search but found nothing.

Went out and disconnected the battery again and reconnected with same results. After some more searching went to car and it started right up no triangle. Here is the strange part, for the next several days the steering was great no shake at all and even the slight vibration was gone. Over the next few weeks it has slowly been coming back again but still not near as bad as it was, I finally got my scanner and scanned it but it shows no codes. I have not seen anywhere if successfully repaired this type of problem without replacing the whole steering rack but maybe I am missing something, anyway I have a couple of questions in my quest not to replace the rack.

1) Is it possible that it has the zero adjust error and my scanner is not reading it?
2) My repair manual(although it does not seem very good) shows resistors with some kind of contacts in with the torque sensors, is it possible these contacts just need cleaning?

Prius C :: Heater Blower Not Working When Cold Outside

I have a 2012 C 3, with 27K miles. This morning on the way to the store i turned on the heater and the fan turned on and after like 2 mins the blower stop working. All the lights are on, but nothing comes out of the vents under any circumstances. I tried taking of the ECO mode, I tried turning the car on and off. still nothing.

If I bring it to the dealer will they fix it under warranty? Could it be a bad fuse? where is the fuse box? What could it be, its freezing outside and I need heat for the kids in the car.

Prius (Gen 3) :: Climate Control System - Could Not Get Cold Air Out Of AC

Recently my Climate Control System on Gen 3 has been misbehaving. A few weeks ago, I could not get cold air out of the AC, and then just as quickly as it stopped working, it started working again. Then yesterday, I started noticing coolant temps on the Scan Gauge rising to 215 - 220 F, which seemed quite a bit higher than the 195 limit I had set for operating with grill blocking, so I turned on the Heater and brought it down to 195, and when I got home, I checked and the coolant level seems OK, and it was under pressure.

Prius (2010-12) :: AC Not Blowing Cold Just Lukewarm Air

Right now it's 101 degrees outside and the A/C on my Prius just ain't gettin' the job done. It doesn't even feel like it's blowing cool air anymore, just lukewarm air. How can I cool down the cabin more? Temps like this only happen a couple times a year here. What do Prius owners do in places like Pheonix where 100+ temps are the norm?

Prius (2004-09) :: AC Not Blowing Cold After Being Unplugged

Prius (2010-12) :: HV Powering Car After Cold Start

This is something I have noticed the last 3 months. I have had the car 2 years. When I first start it and it is completely cold, it will only run like EV mode (HV battery powering the car) even though the gas engine is merrily running and it is not in EV. We live part way down a small hill, so now I often discharge the HV battery to a point low enough to trigger the recharge function which keeps the gas engine running forever. It does this morning or afternoon, if it has been sitting a few hours and is completely cooled off. It did it in Sept. at 65F and it does it now at 35F.

Prius (2010-12) :: AC Doesn't Blow Cold Air

A few weeks ago, I bought a new condenser, compressor, evaporator, expansion valve, ac line for my 2010, 200000 mile Prius and had them installed by a dealership. They weren't too happy about my independent purchase of parts , but they did the job.. After a few days, there was no longer cold air. The dealership is 1000 miles from where I live. They are willing to start over again, for free, and see where the leak is but I can't travel to there for awhile, and, already the heat is oppressive in the middle of the day. I asked the local dealership if they would run a test of the system which will be a bit expensive, and they agreed. But, they cannot guarantee that the test will be conclusive. After almost 3000 dollars spent on this, I really do not know where to go from here.
