Looking for some help here. I’ve got an 04 Sienna in decent shape. A couple weeks ago, the heat went out in the front and back. Blows fine, changes modes fine, if I turn on the AC it gets colder, etc, but neither temp dial (front or back) does anything.
Mechanic said it was the air mix actuator and wanted to charge $1100 to replace it. I’ve done work under the dash already so im pretty confident I can do it myself, but im not confident in his diagnoses. If it’s the air mix actuator...

Hello all. So, I run into a small (hopefully) problem which is intermittent white smoke coming out of the exhaust of my 2012 Sienna Base model with 158,000 miles. Intermittent being once every few days, most often at initial morning start up. A few times at the grocery store or wherever after having driven there. I will note that I did read other threads on here about similar situations but will also note that there is no oil in my coolant and no coolant in my oil. I have no loss of...

I have a 2021 Platinum and driving at night other drivers flash their bright lights at me frequently, sometimes 3/20 cars in 8 miles. Of course I don’t have my brights on and I’m using the auto beams. It’s starting to make me angry ..read more

Anyone attempted to install a solar trickle charger to the Sienna Gen 4 to maintain the 12v startup battery? How would that be accomplished?
I am thinking along the line of installing a permanent cable from the back battery to the front passenger area for plugging in the solar panel that would be sitting on top the the front dash for sunlight power. The panel will be disconnected and removed whenever the van is in use and replugged in when sitting in the driveway.
I am also...

Hello folks, here's my jumper issue last summer.
Jump Star Delima
The fact that the jumper manufacture would not help me was annoying; the gentleman said I did not purchase the device directly from them. Through the years, I feel Volvos are very finiky/sensitive about it's electronic components. I really love and have always believed in this jumper.
Any thoughts?
Cheers ..read more

Solved,check the end of this thread.
Hey fellas. I've been chasing this sound for 5-6 month already and only now, after mechanic visit to check the noise car being lifted, i've desided to check with you, if you have/had the same, because they found nothing (who knows what and how they checked). No loose parts etc. Why chasing, because it sounds like a serious thing to me.
I can hear it only when the car stays parked for some time and then starting the car and slightly pressing gas pedal...

Hello! So, I'm kind of really car dumb, which is a little pathetic. BUT! None the less! I would like to upgrade my Sienna's current radio, with out having to go for an ugly third party radio.
Currently, my current radio is a OEM 86120-08270 radio, and my car lacks the entertainment package. It's still a very nice car! I just want to know if I can get a better radio with navigation built in. I thank you all in advance for you help on this matter! Good day ..read more

Have an 07 Sienna. Alternator went out, so I went out to the junkyard and grabbed one from a Sienna listed as being an 07. Didn't really think much about it. Got it home and it doesn't fit? There's a little flange on the right hand side of the top mounting bracket, about 1/16th of an inch, that keeps it from going on. Everything else about the alternator seems to be the same. What gives?
Edit: Checked in VIN on the donor car, it's definitely an 07 ..read more
