Azera TG (2006-11) :: 2008 - Heater Blowing Cold On Driver Side Vent
My 08 Azera blows cold air out the drivers side vent when everything on the right sides blows heat. If I set drivers side 88 degrees it blows some warm air. I changed the cabin filter and that did not work.

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?
Lexus GX 2004-09 :: Driver Side Hot And Passenger Side Vent Blowing Cold Air
On my 2003 GX 470 w/ 135,000 I have an issue that I can't figure out how to resolve.
The driver side lets out hot heat and the passenger side lets out cold air. I have the dual climate control and both sides are at MAX HEAT with the blower on HIGH. I have 2 vents for each the passenger and the driver.
The left side of steering wheel vent is allowing max heat. the right side of steering wheel vent lets out warm air. Not as hot as left side but warm. On the passenger side, its only letting out cold air and gets colder if I lower the temp on the climate control for right side.
Engine coolant is full, no lights on dash. Blower motor sounds like its working fine.
Lexus RX 2010-15 :: AC Blowing Out Of Vent Is Cold But Rear Passenger Seats Warm
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 ?

Lexus GS 2006-11 :: Heater Was Blowing Cold At Idle And Warm When Driving
2007 GS 350 109,500 miles. My heater was blowing cold at idle and warm when driving so I took it to dealer. To my surprise, dealer says its a blown head gasket. No other symptoms. No white smoke, no smells, no warning lights on dash, and running fine. Just had VVT gear recall done last week.
Fortunately I have Lexus extended warranty good thru 125k miles and Feb 2014. I do my own maintenance (plugs, oil changes etc). Have records for all. But have not done coolant change (due at 100k).
Ford F-150 (2004-2008) :: Overheating / AC Quit Blowing Cold
Will the computer in a 2007 shut down the AC compressor in an overheating scenario because it would be considered non essential? Yesterday on my way home from work my AC quit blowing cold. I just had the compressor changed a couple of months ago so my first though was bad compressor. Then I noticed the temp gauge start to climb. The truck was over heating. There was a hole in the radiator. Now that the overheating problem is fixed the AC is again blowing cold. I just would like to know if I may be starting g to have issues with the compressor again or if it's natural for it to shut the compressor off because of overheating of the motor.

I bought a white 2015 Sonata GLS with 55000 kms on it. Car works fine but really great on gas in city with AC ( 11-12 liters/100 kms ).
And my main problem is my AC/heater vents. Its nice cool day out and I wanna roll my windows up and use outdoor air (with AC off and heating knob on cool - Blue side) but still blow warmer air (the more I turn the temp knob to less cool side more warm air comes out). I went to dealership and complaint about it but they said can't duplicate problem. And I replaced cabin air filter too, but still same problem.
I don't have automatic temperature climate control option, so its all manual, red and blue setting for heat and cold. I complaint them may be my heater stuck on heating but no action taken from them..
Ford A/C :: 2004 F250 - Heater Is Blowing Out Cold Air
Just bought a 04' F250, new head studs and gaskets. Put a tranny temp sensor in and replaced bad thermostat. My coolant res is full and temp is bout 185 (it's 10* outside). My heater is blowing out cold air, I'm assuming there's air in the system.
View 2 RepliesLexus GS 2006-11 :: Heater Blowing Cold At Idle, Warm When Revving / Driving
My '06 GS450h has developed a fault where the heater blows cold at idle and low revs but blows warm when driving or revving the engine at a standstill. The coolant hasn't dropped at all and the car never goes above halfway on the temp gauge. Its starting to get frustrating now the cold weather has set in and temps dropping! Long journeys are ok as at high speeds it stays warm but short journeys are uncomfortable!
I just had a feel of the rad hoses and hoses that go into the matrix (engine side of bulk head) and matrix hoses feel warm (both of them), the top hose to the rad is warm but not hot and bottom hose is cold suggesting the stat hasn't opened yet. Its cold outside so getting the car up to temp is quite difficult without a long drive (rush hour at the mo).
Still I just had the car parked on the drive and cranked the heater up to max and held the accelerator for a while and super warm air blows out. The engine cuts back out as "normal operating temp" has been reached for battery mode and then the heater goes cool again! Still the bottom radiator hose is cool and top hose not massively warm. It has never overheated thus far and I drive 150miles a day back and forth to Reading from Cheltenham 4 nights a week.
Only thing I can think of is a sticky thermostat or water pump not operating sufficiently enough to circulate the water? Its getting colder and short trips where it used to blow warm air nice and quickly (within 3-5miles) are becoming unpleasant!

I have owned my 2008 Rx 400 h for just over two months now and at the risk of sounding dense, am I right in assuming that when you are coasting along without the engine running, the heater will start to blow cold air? Everything works fine until you lift your foot off the pedal. This is my first Lexus/Toyota and hybrid so I'm not totally au fait with how it should be working.

Heater is blowing cold air. What I have checked, coolant level, replaced water pump and thermostat, checked blend door, flushed heater core. When I checked the blend door via the heater treator method I was getting hot air coming off the core but also getting very cold air coming from the A/C evap in side the plenom box. I also pulled the fuse for the A/C clutch and I am still getting cold air. I am look at replacing the HVAC contol.
View 9 RepliesLexus RX 2004-09 :: AC Blowing Hot Air If Temperature Is Not Set To Max Cold
I have a 2004 2nd generation Toyota Harrier (Lexus model RX330). The A/C blowing hot air if temperature is not set to Max Cold. This happened no matter whether turn on the A/C with Auto or Manual setting. This case also happen no matter whether setting the A/C system to Dual mode or not, no matter whether turn on or off the air intake control button.
As long as A/C on, cold air only come out when temperature set to Max Cold, even if set to 18 degree, full hot air come out. Another thing is, say I have the A/C on, set to max cold, cold air came out from the front vent, but after I try to increase the temperature to say 18 degree, the hot air flow will change to Floor/Windshield mode.
Could it because due to the change of the battery? Is there anything need to reset after replacing the battery?
Lexus GX 2004-09 :: A/C Not Blowing Cold Air All The Time
It seems my A/C isn't blowing cold air all the time. It's as if the compressor isn't kicking on or is intermittent. It eventually does, but it takes a long time to cool the vehicle. I've had it about 6 years and it has definitely changed. Vehicle is an '04 with 106K now.
View 7 RepliesElantra HD (2006-10) :: 2009 SE - Heater Cold On Idle And Engine Overheating
A few weeks ago I noticed a fluctuation in my car's heater. The heater blows really hot when driving, and blows cold when the car is idling or coasting. I read up on the forums to check the coolant levels, which were full since my last fluid change a few months ago. The next step seemed to be to change the thermostat. I changed the thermostat and the heater acts the same, and since then the car has begun intermittently overheating. The temperature warning will flash on for maybe about a minute, then go back off. I have been running the heater on full blast trying to keep the car from overheating.
This brings me to a couple of questions:
There's an arrow on the thermostat. Does this need to point toward the radiator, or straight up?
In moving the air cleaner housing to get to the thermostat, I lost two of the little clips that hold it shut. Is this critical?
If the thermostat is good, and the coolant levels are good, there's no air in the system and I don't have any leaks, what could this be?
Lexus RX 2010-15 :: Fluttering Sound From The Heater Vent On Windy Days
My 2010 450h emits a fluttering sound on windy days. The noise sounds like a hvac flap could be vibrating when the wind hits. The noise is not loud by any means, however can get very annoying hearing it everything the wind gusts hit when you are at a stop. The other afternoon I was doing some basic winter prep under the hood and I could hear it under the hood as well.
I got my 2010 as a Lexus CPO early in 2013 and the noise has been there since day one, it's not something that developed recently. The last time I took it in I got a fail to replicate response from the dealership.
