Prius (2010-12) :: 2013 - Vent Blowing Cool Air At Higher Temps?
Feb 16, 2014
I purchased a brand new 2013 Prius 2 last October and I'm loving it so far.
However, I notice that even if it's slightly warm outside, and I have my cabin temp set at a higher temperature than outside, the vent blows cooler air.
For example, the other day it was 65F outside. Since it was warmer than usual, I turned down the cabin temperature to 65F as well. It was nice and cool, but a little TOO cold. So I turned it up to 70F. It was still blowing cold air. I had to turn it up to 72F before it was warm enough to feel comfortable.

I own a 2005 Prius with about 145,000 miles on it. I love it. However, I've noticed that lately, the vent in the back by the window will come on and make a lot of noise. Some research has told me that this is the air vent for the battery that is in the back, and usually comes on when the temps are higher and the battery is starting to get a little overheated.

I knew when I bought my car it wouldn't get optimum mpg as no car would with the many short trips I have to make every day but I have 5000 miles on it already and have averaged approx 46 with all the city and highway combined.
I took it into Toyota last week for the tire rotation and ever since it has been horrible. There were 120 miles on the tank and I refilled because I couldn't stand to see it staying around 39 on the computer. I have never seen that before. I checked the tired and they had brought them down to 32psi so I put then back to 40/38 and refilled.
Not noticing much of an improvement, sadly. Hovering at 40 mpg still. Weather has changed a lot. Temps much higher daily mid 80s to low 90s. This is my first summer with the car and yea the ac has been on nonstop with the higher temps.

I have only 3 days with my new Treg and I cannot make the A/C to stop blowing cool air off the upper vent into the windshield. So the cold air makes condensate water on the outside and I have to use the wipers to wipre it out, appearing again in few seconds. The A/C settings are either AUTO at 70F or manual and making sure the air is directed to the front.

3-4 times since 2012 the low pressure warning light has come on. A few times in early morning with cool temps overnight. Now after service at a dealership where they did a 20 point check, the day or so after picking up, the light came on, the front right tire was low 26-27. I filled the tires and a few weeks later the light came back on, the right rear tire is 1-3 lbs low, I just last night filled all tires to 37 and will check what happens next?

Yesterday the AC worked fine, until I got off work. Then it was blowing as usual, but almost warm air, it wasn't enough to cool the car. When driving and I turn it on, I do see the RPM's lower slightly. A co-worker looked at the compressor and clutch while I turned it on and he said they both are working. He did not see any bubbles in the little window on the line though. The light on the control button is not blinking and the in cabin filter isn't dirty.

So the story goes that one day my 2013 RX350 stop blowing heat from the air vent. I took my car in the dealer to have to take a look. First of all, it took them a WHOLE week to diagnosis the problem, second of all, a consultant told me that he FOUND a pen inside the heater box that caused the gear shaft to break, which is used to control the heater doors...
What is he talking about? More importantly, he's saying I "accidentally dropped a pen" from the passenger side compartment storage and it somehow caused the heater door broke?

I've had my 2009 prius for about a month or so, used of course, a/c was working just fine until one day while parked, I turned the a/c on, put the fan at high and the cooling at low, when suddenly something went "puffff" under the front hood with blow of steam or dust or something like it not sure!
I immediately turned the car off, opened the hood and everything looked just fine, turned the a/c back on, it won't blow cool air no more...

So last couple days over the 4th, the heat was over 95.
AC Blowing out of the vent is cold but the rear seats passenger feels warm.
Even with the blower on the higher and temp on the lowest 65 (or lowest setting).
I put my hand towards the rear seat and I feel warm air. Near the vents are cool but its like the AC can't keep up with the heat ?

I have a 2007 Prius. I turned on the AC for the first time this spring last week and the air blowing out of the vent was ambient temperature. When I looked through the sight glass with the AC running, it looks like there's fluid in there, but it's not moving anywhere and the evaporator pipe did not feel cool. I also replaced the 12 V battery a few months ago, with an optima yellow top battery.
What's wrong with the AC? Will a recharge do it fix this, or did I mess something up with the battery. There were a lot of warnings about "resetting" the system after you have the 12V out, but I didn't seem to have any problems that were described as symptomatic of needing a reset.

I have a 2008 Elantra with 78k miles on it. Yesterday, to my dismay, I couldn't get any hot air out of my vent. I have never once had an issue with the hot or cold airflow before.
My coolant level is good and the temperature gauge is a-ok. The air coming in was cold yesterday and cool today; it appears it's just outdoor air temperature (as opposed to straight up cold) that I'm getting.
I believe my radiator is also overdue to get flushed...not sure whether or not that has anything to do w/this.
Is this likely the blend door actuator? I'm no car guy but I've been reading a little. Also....looks like this part might be 40-50. How much do you think I should be paying for labor if this is fixed?

My 2010 HHR vent and hot/cool controls do not respond when turned. Only hot air will blow out the dash vents. This happened last summer, but returned to normal until now. How to repair this? AC light and compressor come on, but still only HOT air comes out.

My temp gauge (which very seldom deviated form its position) is showing above normal temps. Yeah its over 90 here but this is unusual for my car to run hotter. I put in a new thermostat about 3 years ago. I've also been adding water/anti-freeze because there was a small leak (that I finally found in the hose) that I corrected. Could it be that my mixture isn't a 50/50 mix or is it my thermostat again? They say they don't last long anymore???

Took a trip today that was 3 hours there and 3 hours back. Truck ran normal on the way there (eot about 202 and ect about 196-198), but on the way back truck ran a little hotter than normal (ect as high as 214 eot stayed within 2-3* plus or minus ect). Fan did kick on every time I hit ect of 212 and would drop it down to 196-198 and oil temp would drop at the same rate.
Truck is stock 190k miles with a bulletproof egr cooler and coolant filter. Oil cooler probably has about 20k on it. (4th one on this truck- since I like changing them out as much as the rest of us). I checked coolant level when I got home and I might've added a pint to get to bottom of sticker. I'm not sure it wasn't a pint low when I did last flush and cooler replacement.
No puking and I can't find any leaks. I pulled egr valve and no moisture in manifold just a worm out o ring that'll I'll replace. I can't find any leaks. Where to check that I haven't? I don't feel like I'm losing coolant because I wasn't really low. My fan never failed to kick on when I hit 212 or stopped at a red light. No moisture in manifold so I'm not thinking losing coolant due to head gasket. Maybe radiator looks ok but tomorrow I will blow out any bugs to make sure.

Fuel mileage dropped from 52 to 40 on several hot days and I heard a constant loud hum. In the shop tomorrow.

Was getting around 52.5 MPG in warmer weather, changed the tranny fluid and normally people report an increase in MPG. We're now getting around 50.5 MPG, so a 2 MPG loss. In addition, temps have gone from around mid-80s to mid-60s. Wondering if that would explain the MPG drop?

So I changed my oil today and added about 9.8 - 9.9 quarts. There was just a little left in the second 5 quart jug. I carefully added some oil while checking the dip stick frequently. I made sure the level was just at (maybe a hair above) the top dot on the dip stick. After that, I went out for a spirited drive.
Now 4 hours later, when the car is relatively cool, I checked the level again. However, the level is now significantly higher than before. It's definitely past the top dot, not by a lot, but definitely more than before.

Last week I switched my wheels and tires out from OEM 15 x 6 wheels with 195/55R15 Good Year Fuel Max tires to 16 x 7 Drag DR9 wheels (16.55 lbs.) with 205/50R16 Good Year Fuel Max tires. ( I wanted a different look) At first I didn't notice any change in mpg's, but that soon changed. The temps went down into the 20's for lows and 30's for highs. I went from 48 - 50 mpg to 41 -43 mpg in just a few days. I assumed that the drop was due to the cold weather. This morning I decided to check the tire pressure in the new tires. 32 psi all the way around. I asked the guys that installed the tires to fill them up to 44 front, 42 rear. I guess that never happened. Anyway, I looked on the sidewall of the tire to check max pressure and I was shocked (51 psi). I ran 44 front, 42 front on my old set, because that was what I was advised to do.

I had just picked my kid up from school, as I turn out of the parking lot my A/C stops blowing cool air, I check the A/C screen and it still says it's set on High with temp at 68. However, it is blowing very low with warm air. Seconds later the dash lights up with numerous warning lights. I'm on the highway and I'm able to gather speed, but each time I do I hear the engine revving like crazy. We only live a few miles from the school so I am able to make it home. Once home, I turn off the car and turn it back on. The only warning lights displayed now are the red triangle and the yellow check engine light. I turn the car off, pop the hood, I check the belt and it was fine. I checked the oil and it seemed fine. I check the coolant overflow and it was empty.
