Lexus GX 2004-09 :: Driver Side Hot And Passenger Side Vent Blowing Cold Air
Nov 27, 2012
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.

I have a 2004 Chevy Tahoe with the 4.8L V8. My A/C is blowing hot on the drivers side and cold on passenger side. There is only one controller, not two. What the problem could be...and I'm scared to ask...how much it may cost to fix? It has happened only one other time and that was a year ago, and it has worked fine since then until today.

I have a 2008 Santa Fe Limited. Today I briefly turned the heat on since the outdoor temp was cool. Later in the day, I resumed the A/C AUTO setting at 72 for BOTH sides of upper vent outlets. I soon noticed that the driver's side blows warm air and the passenger side blows cold air as it should. No amount of adjusting the temp control either up or down had any effect on the driver's side except for constant warm air. Now I know the passenger side can be adjusted separately but both sides were set for the same temp. Never had this happen before. Always before, if I wanted warm air, the warm air would come through the floor outlets. What's causing warm air to come out the top driver's side vents when it should be cold? Could a diverter door be stuck?

2006 GX470. I have an A/C issue where sometimes the driver's side is not cool at all but the passenger side is very cold. Both sides are set to the coldest setting.
The weird part is, I can usually get it to fix itself by reaching back to cycle the rear A/C on and off.
I did a search on here and found one similar thread, however it seemed his fix was replacing the expansion valve; but wouldn't a bad expansion valve cause an issue to both driver's and passenger side?

I have a 2005 Avalon Limited. Just recently when I have the air turn on, it blows warm/hot air on the drivers side where the passenger side is cold as ice??? What gives??? I have the dual zone feature, and the drivers site is warm weather its on dual zone or regular.

My A/C is blowing Cold on the drivers side and very hot on the passenger side. I need to know if it could only be the Right Actuator or if it could be that or the temp control module or low refrigerant or low coolant. I am Disabled and need to know how to track it down before i order an actuator.

Where the Air Door Actuator is located in the Elantra 2014, and How to reach it?
I want to check it as my AC is blowing Hot air from driver side and Cold air from passenger side.
I read that there are 2 of them, one for temp control and another one controls where the air goes, one at the passenger side and one at the driver side...
Which one should i start with, where is it located, and how to reach it?

My 1.8 2014 Elantra AC started blowing Hot Air from Driver Side and Cold from Passenger side and i noticed this after a battery problem. It all started when battery problem, suddenly both sides warm ac, i took it to a mechanic, he said nothing to do with battery and said it is a freon problem, he fixed it for 1 day or 2, and i went changed the battery, then suddenly, one side hot and one side cold.
Things i tried:
1. Removing AC fuses for 1 hour
2. Removing AC fuses while car on and then turn off car and replace fuses
3. Changed car filters
4. Hot cold hot cold switching technique
5. No freon leakage
Temperature here is around 120 degrees so you can imagine!

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.

I have a Buick park avenue 1998, 3.8L V6 engine. the problem is: The ac vent on the driver's side blows cold air but on the passenger side blows EXTREMELY hot air. no matter how cold or hot you set the ac it blows at the same temperature on both sides. Florida heat is setting in and my passengers are melting. I am really hopping that is not something to bad and that I can fix it myself. Tip: this started happening after i had the alternator and the battery replaced.

I have a 2009 Lexus ES350. For some reason I got in the car today and I turn on my car and turn on my AC unit on, the driver side ac vent was blowing warm-cold air while the passenger side was blowing nice cold air. I thought it was my fuse, so I disconnect both AC fuse for a hour and reconnected back on and noting change.

I have a 2004 Chevy Venture and the blower (Vent, AC, Heater, doesn't matter) is only blowing air out of the left or driver side of the van, nothing on the passenger side vents. There aren't 2 blower motors, are there? Is a door shut that shouldn't be? This van doesn't have dual climate control like my GM cars do. The rear controls work fine for the 2nd row passengers. Again, not tied to any blower speed or heat vs. AC. Same regardless. Nothing on the passenger side.

I bought this 06 Prius in April and it has been a nightmare. I have an 05 and thought "I love this car so much, I want another!". I didn't do a good job inspecting the car before I got it, but oh well. Here we are at the dealership because my Driver side AC was blowing warm and the passenger side was nice and cool. $300 later, they call me up and say they have drained all the Freon because theres an obstruction causing the pressure on the high side to get so high that the compressor purge valve has to kick in and their AC machine shut off to protect the car.
He said it would cost 1700 to replace the Expansion Valve and the Receiver Drier, and that they weren't positive that would fix the issue, but that its the first step before replacing the Compressor. He said normally they'd suspect the compressor is going out, but he said it appears to be operating okay. Their opinion was that there is an obstruction in the line - most likely some sort of metal - which is causing the obstruction and the pressure on the high side to go to extreme levels.
Pressure on the low side he said was okay.
Here is the text from the service receipt:
Performed A/C inspection and all vents appear to operate fine. No leaks seen. Lots of debris in front of the condenser. Suspect system low on Freon. Perform evac and recharge. Installed dye.
Pressures:
High: 130psi
Low: 15psi
Used 1.1lbs of freon then noticed the restriction. Removed freon. recommend replace expansion valve receiver dryer, flush lines and replace all necessary o rings.

When I turn on the heat, I only get hot air through the drivers side vent,the passenger side vent is very cold. I had it in to be worked on (at a Non-Toyota shop)and they tore it completely apart and could not diagnose the problem. It affects the entire system,meaning the air going to defrost is also hot on the drivers side and cold on the passenger side.

Awhile back I did get my battery replaced and I did reset my windows so they could be used from the driver side panel. As of now, I can roll down all of them from the driver side except for the passenger side rear (window diagonal from driver). The window does roll down from the door itself so the window isn't broken. The light on the driver window switch is lit green, not blinking. However, the light on the window switch on the passenger door is NOT lit and not blinking either. And yes, I did make sure the window lock was not on.
Could the switch, either passenger or driver door, be bad? Should the battery be disconnected and reconnected??

I own a 2008 Toyota Camry. Yesterday I noticed that cool air is only blowing out on the passenger side and not on the drivers side.I topped off my refrigerant to see if that was it, but that wasn't the problem. What could be the issue?

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 ?

My Hundai Azera 2009, was blowing heat on both side of a "dual system" during the cold months. Now that its warm weather when I turn on the A/C it blows cold on driver side vents , but hot air on passenger side. What do I need to correct this.

Why my air-conditioning only blows cold on the passenger side on the driver's side It barley bows cold most of the time it is warm.

History - So my A/C was going out about 6 months ago. It would come in and out with cold air until eventually it just stopped all cold air and was only hot. Then the control knobs broke. I took it in and they told me I had to replace the control unit and that would fix all the issues. Well I got it back and the A/C was still blowing hot air (even though the knobs were now working).
So I took it back in and they said they couldn't find anything wrong and it must be this hairline crack that was leaking freon. they said they couldn't find the crack but loaded it up with freon and said i would have to 'wait it out' could be years could be a few weeks, they just didn't know. well, it worked for awhile but here i am in 102 degree heat and when I turn on the A/C in the really hot car the passenger side quickly blows cold air and the driver side takes about 20 minutes before it finally gets cold. What gives? I do not have dual temperature controls.
