#152 of 161 2011 highlander a/c blows warm by sillymama

Aug 25, 2011 (8:40 pm)

Just drove a 2011 highlander off the lot 5 days ago. Air blows warm for 6-9 minutes after car has been sitting for awhile like in garage overnight. Took it in they found leaking o-ring and filled the freon. Again brand new car 200 miles. Still blows warm- left a baseball game tonight after the car sat for 3 hours. Took a/c 5 minutes to blow cold. It literally blows warm air then seems to kick in. Service mgr tells me it takes the highlanders 5 minutes to cool the cabin. It takes mine 6 minutes to blow cool air. Any similar problems? Considering taking it back. We live in a hot climate and our 18 year old BMW cools better. Help

I had the same problem with my 2005 Highlander. Googled it and tons of people had the same issue. If you take it to Toyota they tell you they have to replace the whole board which costs about 1k. In actuality it is just that two of three wires coming to the control button has come undone because they are too short. You need to just have them resolder on the other side and it works like new. Cost me $40.00. I can't remember the site but if you look hard enough you will find it where a guy give you detailed instructions on how to fix it with pictures.

Did A/C improve at all after repair? You might want to ask your dealer to let you compare any other new HL cooling with yours, see if any difference. I have a 2008 HL and A/C might take few minutes to cool off if car seats for long time on the sun. I can feel cold air coming from the vents pretty soon though, whole cabin space might take time to cool off if it gets really hot. If you live in hot climate then you should have chosen optional rear A/C when you bought the car.

model year? I have a '05 and initially I had the same problem that was remedied in msg #155. Problem occurred again this winter and it turned out that the "blender door" control is broken. It controls how wide to open the door (underneath the dash) to blend the warm/cool air into the cabin. Right now, I have a stiff wire propping the door wide open to get me thru a Chicago winter. I only get one temperature control HOT or OFF. Not sure if this is your problem, but it's my experience with lack of temperture control.

#159 of 161 Not cooling well, so added freon, made it worse by k8rad

Jul 01, 2012 (6:19 pm)

The A/C in my 2007 Highlander was not cooling as well as it used to, so I added freon. As it was going in it made loud noise that sounded like pressurized air releasing from the lower part of the compressor facing the lower front part of the car. This loud noise occurred for a second or so, every 10 seconds. The A/C does not blow cold air now. If anyone can let me know what to try next, it would be appreciated. Thank-you.

#161 of 161 Air Conditioner/Heater Problems by grannyjll

Had an appointment scheduled for tomorrow with my local Toyota dealership because I was having problems getting my 2005 Highlander's AC to work. After deciding to check and see if anyone on the Internet had posted a similar problem, I was very glad that I did. On my way to lunch I removed the control knob to check out the hex nut that was mentioned on here and sure enough it was loose enough to spin around. I tightened it with my fingers and my AC and heater work beautifully now. This 56 year old granny is proud of herself. Thanks for this blog and the helpful information all of you posted. I was really scared to see how much I was going to have to pay to get my car fixed.
