I recently had my Sienna in the shop to diagnose and repair an intermittent A/C problem. A/C occasionally doesn’t cool down vehicle well on hot days, especially in stop and go traffic, but usually works ok in cooler weather and at higway speeds. Shop diagnosis:”technician noticed a...

I've been trying to troubleshoot some weird A/C behavior on my 2011 LE (Canada). The system is chilling well (1-3C/34-37C from the vents) but it keeps shutting off when it should be running. If the van is warm and I restart it with the A/C on, it often takes 10 minutes or more before the A/C...

On our 2007, we rarely (never) use the rear A/C or heat. I'm thinking we should run it once in a while to keep things lubricated or something. If so, how often and for how long? I don't know how the thing works, and what could go wrong. Thanks!

I am having trouble with the a/c on my 2007 Toyota Sienna (XLE) Limited. About 12 months ago the servo was replaced for the passenger side as it had begun blowing cold air no matter the temperature setting. They had to replace that again under warranty approximately 6 months ago when the same...

I have seen a lot of postings on this topic but none quite addresses my issue. I have a 2008 Sienna LE. Last summer I noticed that the Driver side front A/C was not blowing out cold air whereas the passenger side was ice cold. I have seen many postings here saying the adding more freon can fix...

Our 05 Sienna has been a beast for 300,000 miles without fail now but yesterday it started overheating when the motor is idling and the a/c starts blowing out hot air. When I drive it cools to the proper point but then heats up again when stopped. The fans are working properly and kicking on...

We've put nearly $1,000 into our 2007 Toyota Sienna's air conditioning system. I believe the first mechanic misdiagnosed, and started by replacing O rings, then an entire line. Then the a/c failed again and the shop charged it. It worked for a couple weeks, but soon the drive side vent blew warm...

Hi, recently just replaced the A/C compressor and electrical relay module on my 2012 Sienna and the A/C still doesn't work. The error code is B1479 which indicates a bad flow sensor circuit which is in the brand new compressor! I trust the mechanic who did this work but I'm now into this...

Hi all, I am assisting a family with a 2006 Sienna CE. They have no money (a refugee family) so I volunteered to help out. The heater has been finicky since we got the van. On occasion, the heater will stop blowing hot air. A/C still works fine when I activate it. The rear also blows only...

2008 Sienna LE, 130,000 miles. For the second winter in a row, my AC is turning itself on when I'm trying to heat my cabin and defrost my windshield. The button with the green light just suddenly lights. I can hit it and bang on it enough times and it usually eventually turns off. I try...

I have a 2008 Sienna and I have been trying to get my A/C back to working normal. The tech that's working on it already replaced the condenser and the compressor but it isn't blowing as cold as it once did. Anyone have any similar experiences?? I need to get this working again it is so hot where...

I have owned this car from new, and just in the last day have had an issue where the recirc button on the dash comes on and turns off by itself. It does turn on/off the recirc function, but not by my intention. It is an LE with manual dual zone climate control (front/rear), we are in TX and...

We have a 2004 LE the A/C is not functioning Here are all the details I know: All the lights on the Dash work as they are supposed to. The A/C clutch is not engaging (not spinning ever) The cabin air filter is brand new(had to replace it once in the past when A/C wouldn't work something to do...

Hello all, I'm new the forum. I have a 2011 XLE. Just realized on Sunday after the daughter complained "it's hot back here" that the rear blower motor was not working. I don't know for how long. I've looked at the fuses and all look good. So far I have not found much out there on troubleshooting...

The AC works just fine in my 1998 Sienna, except that we have to hold the AC button down for it to stay on. I have already tried swapping the two relays under the steering wheel, but I don't know if either one was the AC relay. Any ideas? It's getting warmer and my improvised solution...

Just wondering if anyone has any history of A/C compressor issues. I have a loud squeal on startup that goes away in a few seconds (this is with the A/C turned off). If I turn on the A/C it is a continuous squeal until I switch the A/C back off. I have replaced both serpentine belts (Air...

Dealer says the system is charged, clutch is working, and system is functioning. I hear this ticking noise coming from dash and took this video of the noise from the driver's side footwell looking at the center stack just above the kick panel: Any idea what is wrong? Is it the actuator?

At a loss. Changed the timing belt, water pump, power steering and A/C belts yesterday. Engine fired right up, ran with heater on full hot until thermostat opened and topped off coolant. Then switched to A/C and it blows hot. A/C worked the day before I did the service. Both radiator fans...

I have a 1999 Toyota Sienna XLE and when I'm at idle the a/c blows weak and the dome light/ instrument panel lights flickers. When I'm on the gas and moving the a/c blows strong and works normal. The battery and altenator have been replaced about 5000 miles ago. Plus I've noticed that sometimes...

hey ya'll, i have an '04 sienna le that is giving me issues. The A/C only works when it wants to. I tried to recharge it with the engine running and a/c on like i should and got a heck of a shot of refrigerant. So obviously it has adequate charge. After doing some more digging and asking around...
