Where is the Air conditioner receiver located?
 
A picture shows it on one side of the condenser.
 
Possibly on the driver's side. A plastic cowling needs to be removed
 
to expose the condenser - I see plastic "buttons" holding it in
 
place.
 
Condenser is located in front of the radiator.
 
Pictures are accessible by membership at your
 
local Library - they are ok

Problem fixed. Replaced Servo assembly , part number 87106-08060,
at the dealership . No luck with first DLR, but 2nd one showed more interest in helping me.
 
I mentioned the rear A/C panel being locked in auto mode, but this is OK, and do not know how it is no longer in that state.

My 2007 Sienna's A/C does not work. The compressor clutch engages but does not seem to pump. I had a tech put it on A/C gauges, and it read no movement on the pressure. He said there might be a flow switch somewhere. Any ideas?

Open the hood, turn engine ON, turn A/C ON. Watch your fingers...
Cooling fans behind radiator should be running...(if not, no cooling)
There are two A/Clines on the passenger side of the engine compartment - the larger diameter one shoud be HOT to the touch, and the smaller diameter one should be Cold. This should happen within the first minute or so of A/C operation. If this is not happening, get a tech who is interested in helping you, and by the way - some A/C gauges are such that they fail to push the Schrader valve center pin , and no "action" is registered by the gauges. Adapters may be needed. Not sure if this the case in your Car, but it is in my other vehicle. The A/C comp clutch is "picking" that indicates to me that the system has refrigerant but may be in need of some, but get another HI/LO gauges reading before adding.

entry #162, 2nd sentence - should read:Cooling fans behind radiator should be running...(if not, this results in no A/C cooling) ...

#164 of 179 Engine fan making weird sound and running quicker than normal by dmanatine

The engine fans are running faster than they normally do an they only do this when the engine reaches a higher rpm. It also makes a vibrating noise when they run faster.

Anyone know about this.....
 
I have an 04 sienna that when the HEAT is turned on it blows cold air(AC?) on the right side vents , and hot on the left side.
 
Bizarre, just started this out of nowhere?

There is an air mix box in the center of the dash behind the middle vents that contains both the heater core and the AC evaporator. CE & LE models have one temperature air mix solenoid & flap, while the XLE has two (separate left and right controllers & a more upscale split mixer box. The hardware and controls are different, so which van are we talking about?

in My car AC or Heat turns on only when car is running on 40 miles or more speed.
As soon as car stops at traffic light or it is in park position heat or Ac does not work. while in park position cooling fan runs rapidly and makes noise.
I added coolant in radiator. Heat indicator in Auto meter panel after car runs few miles remains on slightly higher then middle position.

#168 of 179 2009 Sienna rear heating problem by mhw1

Dec 23, 2011 (12:19 pm)

I have a 2009 Sienna and we noticed last night that the middle and rear vents were blowing cold air while the front vents were blowing hot air. We let it run for 15-20 minutes, tried turning it on and off and everything else we could think of. Does anyone know what is wrong.
