Toyota Sienna Compressor Questions

jgcox6 on Sun April 24, 2011 11:21 AM User is offline

Year: 2006
Make: Toyota
Model: Sienna
Refrigerant Type: 134a
Country of Origin: United States

I have a 2006 Sienna and have heard stories about the toyota sienna compressors,,,especially on the 2004 -2005 yrs. I heard that they prematurely go out and the whole system has to be replaced. I am wondering what you guy's experience on these are? Have you heard about a TSB that was out to install inline filters? Have you heard of the 2006 models "fixing" the problems and installing an inline filter? Do you think the compressors were under oiled?

I have 2006 Sienna as well -- about 62,000 miles. I'm currently on vacation, and am hoping it will last the 1200 mile drive from Texas home to Utah. It started with slight compressor noise, then moved on to A/C working when it felt like it. It's still in that stage, but last night I experienced my first belt squeal when starting the car with the AC on.

I'm going to replace the compressor when I get home. I'm hoping mine has the inline filter that was supposedly installed for the newer Siennas due to the cheap compressors and multiple failures on the pre-06 models. If not, then I'll replace the condenser too, and flush, flush, flush and hope nothing got past the orifices to either the front or rear evaporators.

If the compressor seizes up on me, I hope I can get it shut off before the belt breaks. The drive is pretty desolate between Amarillo and Albuquerque, then from there to the Utah border. I think I'm going to buy a spare belt before I strike out.

you might want to check to make sure that the belt is not the issue....my belt started slipping causing the compressor not to get the full "pull". I tightened the belt to within specs and all is well....at least for now.

hmmm... didn't think of that. It's the noise the compressor is making that's got me concerned, but I will definitely have a closer look at the belt.

On the way home to Salt Lake from Ft Worth Saturday, the AC quit working near Tucumcari. ...just under 64,000 miles on the odometer. I suppose I should be happy the belt didn't snap, though I had purchased a spare before I left Texas.

It made for a HOT 800 mile drive across New Mexico and southern Utah. At least it wasn't 107 like the day before in the Ft Worth area!.

Now, I'm trying to figure out what happened. The AC clutch will not turn on, though the system appears to be fully charged (~110 psi on low/high side with engine off). I can turn the compressor by hand. Maybe the clutch failed for some weird reason? Maybe it was the clutch making the noise the whole time.

At any rate, I'm still trying to figure out what went wrong. It's very tight in there to fiddle around. I reckon I'll have to pull the compressor in any case.
