"Yes, that's correct. Check which way the arrow is pointing on the temperature knob before you pull it off, so that when you push it back on, you align it the same way." better yet, turn it all the way (either way) before you remove it, then it will be easier to get it back aligned the same. |

I got 01 Highlander V6 with non-auto temp control. My A/C is fully charged but intermittently I don't get cold air. I know this cuz I have used temp guage and know the temp when cold and warm. The temp setting knob works fine. But do not get cold air, while driving intermittently it will start sending cold air but consistently. Anyone run into this problem and know the fix. Any help is helpful.

Replying to: vdeam (May 16, 2008 6:13 pm) never take your vehicle there. I would say 90% of dealerships are crooked |

Replying to: wwest (Jun 29, 2008 6:40 am) Are there sensors that prevent it from turning on?

Here in the Las Vegas summer heat the A/C doesn't get the vehicle to cool as quickly as expected (+20 minutes). Has anyone else had similar problems?

Replying to: khenkel (Jul 18, 2008 9:04 pm) I'd take it to the dealer as it has probably lost some gas. The Air Con is super efficient and copes well with Australian summers (similar to Nevada) so there sounds to be something not wrking correctly Cheers Graham |

Replying to: khenkel (Jul 18, 2008 9:04 pm) There are times when Toyota's design engineers seem to be a little TOO concerned with passenger discomfort and "this" is undoubtedly one of those times. You can be cool the cabin down quickly by discomforting yourself briefly with system airflow that is a bit TOO cool. First, move the temperature setpoint to the COLDEST position. That should result in the blower speed going to the highest level once the A/C begins cooling the airflow. It will also, typically, result in the system switching to recirculate mode. If so then immediately switch it back into fresh mode and lower the rear windows an inch or so. The object of this "stage" is to move the "super-heated" airflow out of the passenger cabin and in the process hopefully reduce the interior surface temperatures slightly. Over time and trials you will begin to be able to judge when to switch to the next stage. Now switch the system to recirculate mode and lower the blower speed to adjust your noise intrusion comfort level. At this point the lower the blower speed is the lower will be the temperature of the system airflow. If you continue to need it cold, TOO COLD, in order to more quickly cool down the cabin then you might want to switch the airflow to footwell or mixed dash/footwell mode. I found it helped quite a bit cooling wise, COOLDOWN, to purchase and install a manual water flow shutoff valve in the engine coolant flow line to the heater core. That not only serves to bypass the reheat.remix mode of the HVAC system but results in a significantly lighter load for the A/C compressor and thereby an improvement in FE. |
