Question about 2009 Toyota Venza

1 Answer

Dual-Zone AC Problem

When the AC is set to "LO", regardless if it is in "Auto" climate control mode or not, and the temperature outside is 85+ degrees, the driver's side AC system blows warm air while the passenger side blows freezing cold air. After the car warms up and is driven approximately 40 miles, the driver's side gets cold, but not AS cold AS the passenger side. What could cause this problem, a temp sensor or a switching mechanism?

My guess is that one of the hose's has a leak and needs to be replaced. A mechanic can run some tests to check if that's the case. Best of luck.

This is Caused By the Grease in the Spindle Bearings Getting frozen. Get it Greased up really Well and you Might need to Repack the Bearings on this side to Stop this and Stop further Damage to the Spindle.

If the driver's blend door actuator has failed completely, or the wiring to it is damaged, you will not hear any clicking. Check for appropriate voltage at the blend door actuator, and determine from there if it's the actuator or the control unit.

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

First thing that started the outside temperature reading would flicker and finally settled to the steady reading. Then we started getting cold air on the passenger side and warm air on the driver side. ...


That is two separate problems. The "Flickering" of the outside temperature thermometer might be normal to some extent. Sometimes, the voltage from the sensor is at a point where it could be say, 31 degrees F or 32 degrees F. The display may flicker back and forth between 31 and 32 very rapidly until the voltage changes just enough to go make it go solid one way or the other. It probably does this all the time, but you didn't notice until you were paying attention to the temperature problems inside the car. (One actually has absolutely nothing to do with the other.)

The cracking and popping noises you are hearing from the temperature door and the difference between the temperature on the driver's side and the passenger side are the same problem. Apparently, you have dual zone climate control. This is usually caused by one of the temperature doors sticking and either stripping the gears inside the door control actuator or breaking the door itself. If you have both sides set at "HOT", the side that is cold is your problem-child. This will usually also set a fault code in your climate control module and may make your climate control display flash. (but it doesn't always flash when there is a code present)

WHen we use the auto car starter, it blows cold air, and a lot of it. Its nearing the winter here in New England and I need to know how to set up the starter to blow warm air. Any ideas?


Start the vehcle and let it warm up then set all the controls to heater? Then turn off the car. Use the remote start to start the vehicle and check the controls are still set to heat mode.

A/C comes on every time I start vehicle. Not in auto mode. Even when dual climate knobs are turned to high, A/C still comes on. Why ???


Check to see that you have not depressed the AC on button its a small push in button bellow climate controls also on your temp setting turn it to the far right this is the warmest setting this will prevent auto kick in to the AC you may also turn blower knob to off This position turns off the blower motor and outside air
will not pass through any outlets.
