  1. Problems, Maintenance, and Repair (Gen 1)
    Hi, my 2000 sienna ac temp knob gets stiff and stops right around where the blue color indicator starts and will not fully turn into the red either. I removed the radio panel and can see that the plastic lever is entact and pushing the wires as it should. I checked beneath to where the wires...

    We're thinking of getting a small generator and a standalone AC for when we're camping / boondocking. This will mostly be so baby can comfortably nap in the Sienna during the day while we're camping and so we can leave the dog in the car while we hike. We tend to camp in places that are cool at...
  3. Problems, Maintenance, and Repair (Gen 4)
    Hi All, I have a 2021 XSE AWD and I noticed that when the car is turned on and I'm not driving, that cold air stops coming out of the vents. For example, my wife and I were going through a fast food drive thru yesterday and the van was cool when we got to the restaurant, but by the time we got...

    TLDR - Context - 2013 LE, located in Central FL Background - Blows lukewarm air in Driver Side, and Rear AC. Passenger cold. (lukewarm out of cabin filter slot though) 1. DIY Refrigerant added, says it's in the green 2. Blend Actuators appear to be working correctly 3. Condenser doesn't seem...
  5. Problems, Maintenance, and Repair (Gen 2)
    Hi all, I have been chasing this issue for about a year and I could really use some help if any is out there. :) A bit over a year ago when I was preparing to move from Houston TX to Scranton PA, I didn't have time to do some scheduled maintenance on the Sienna so I dropped it off at a local...
  6. Problems, Maintenance, and Repair (Gen 1)
    The other day I noticed a leak from behind the air conditioner on the passenger side, after it was running so I thought it was from the A/C. I stopped by Oreilly and the guy told me AC doesn’t leak water and that it’s probably cooling System related, there is no sign of coolant leaking. I...
  7. Problems, Maintenance, and Repair (Gen 4)
    Hello all, I had a question and was wondering if anyone else was going through the same thing. Over the last couple of days when I’m the van I noticed the ac was blowing cool air- but the cabin wasn’t getting cooler. I would go out and do errands and I’d be sweating when getting out of the van...
  8. Problems, Maintenance, and Repair (Gen 3)
    Hi, We have a 2019 Toyota Sienna LE with 16,000 kms in it. I noticed the AC blows stinky air every time i turn the A/C On and air to recirculated mode. Cabin filter is still clean and good. Anyone from the group has encountered this or has any recommendation? When we used to own a 2006...

    Even running through a small puddle can cause the AC to quit. The AC light flashes and it doesn't cool (or dehumidify) until you turn it off, wait 20 seconds or so, then turn it back on. My assumption is that the water from even small puddles is being thrown onto the AC drive belt and that...

    Hey Guys, The first time I noticed this was a week ago when the outdoor temp was in the high 80's. Turned AC on Max, front only and waited parked with engine running for a few mins before setting out. Only lukewarm air came out of the upper vents, the mode the vents were set for. I...
  11. Problems, Maintenance, and Repair (Gen 3)
    We have a 2011 Sienna. Several months ago we started experiencing behavior with it where the AC would stop working for awhile and then start up again. Let me elaborate. . . The AC will be on and working fine when all of a sudden we realize that, even though the fan is on and blowing air, the...
  12. Problems, Maintenance, and Repair (Gen 2)
    Hello, I have been trying to do some small maintenance for the Toyota Sienna 2009 minivan and one of the things was to take the blower fan out and clean it up. (I somehow got squirrels/chipmunks to invade my car and made a small mess (acorns in the fan in the cabin air filter). I have already...

    No heat on Passenger side only on drivers and rear. Mechanic said almost 900 to fix "actuator" I would love it if someone could help with some instructions and or part numbers to order etc.
  14. Problems, Maintenance, and Repair (Gen 1)
    Hello there, anybody know how to clean/deodorize the conditioner of a 1998 Sienna? I've been looking for an air conditioner filter but I can't find it. I bought it second hand, but they mentioned that they haven't taken care of it for months and left the windows open. Now every time I use the...
  15. Problems, Maintenance, and Repair (Gen 2)
    Hello Everyone, I am afraid we may have treated a symptom and not a cause. Our drive belt on our 04 Sienna would squeal for a bit on start up when the AC was on, but the squeal would go away after 15-20 seconds, or when driven. I had had two places check the belt when I took the van in for...
