Thank you very much for the info. This makes a lot more sense. I'm glad you followed up on your dilemma. That's crazy that your van started doing this with only 4,000 miles!
Any chance I can get you to note the Name of the Toyota Dealership that ultimately fixed your problem?
I'm dealing with the Toyota Dealership Don McGill in Houston, Texas. The service manager keeps trying to tell me its bad gas because it won't throw a code, but I know better. I'm hoping they can reference your dealership for the fix, so I can resolve this issue once and for all.
#19 of 24 98 sienna power window intermittently fails, XLE

Sometimes the power window won't go up until I shut off all other electrical drains (fan, cell phone charger, gps...) and drive around, and then it will go up bit by bit. I wonder if it is related to the power stored for raising the window in the first minute after the car is shut off? Very scarey when I'm on my way into a car wash!

Another forum refers states a faulty load sensor in the power window motor is the problem causing the window not to raise until you drive around for a while. But, Toyota doesn't sell the load sensor unless you buy the window motor, too, so repair is about $500. Does this make sense to others? To me it seems like the motor just isn't getting enough power, so driving recharges the stored power. Why would driving around make the sensor malfunction stop?

A load sensor problem makes sense. This is the device that stops the auto-up window from slicing off your hand if it gets in the way. It works by monitoring the current draw by the motor (when working harder the motor pulls more current), and throttling it back if it senses trouble.
At idle, your alternator puts out limited current. If other accessories are running, system voltage drops. This aggravates a sensor issue as voltage and current are related (power in watts = volts x amps). Shutting off accessories or driving around (engine RPM is above idle) has the effect of raising the voltage, and thus the power available.
A second possibility (remote) is that there is a window track problem that is triggering the limit sensor due to high friction. When the van is in motion, vibrations and bumps may work to help the window move in the track. And when the accessories are off & driving, the higher power available (see above) helps to push it along.

Hi. Did you ever get the name of the dealer that had the resolution to this problem? My wife's car started this today and I want to resolve this under warranty ASAP. Thanks!
#23 of 24 Fuel Injection Issue Resolved
Nov 28, 2011 (7:11 am)
My starting issue was finally resolved, but by far it was not an easy task. The dealership finally replaced my fuel injectors and I have not had any more starting issues since.
As you can see from the previous posts, your more than likely going to have to make a many trips to the dealership.
I had all my work done at Don McGill Toyota in Houston, Texas. I don't believe your going to find a Toyota dealership that is going to willing want to do the work. The service sheet for parts and labor totaled over $1,400.00, but fortunately for me the warranty covered it.
The service manager was very very hesitant, but one day to the next he suddenly said he was going to do it. He mentioned that a Toyota specialist was in town to look at another vehicle, he says he remembered my Sienna and happened to ask him if he'd ever heard issues with the fuel injectors. The specialist noted that there was a bad batch of fuel injectors that got out and this was apparently the only reason he did the work.
I would highly recommend you have the dealership do an in line fuel injection service. This is about a $200.00 service, but it can weed out a lot of problems. I did not have all the other things replaced like a few of the other guys. The main problem to me is apparent because all I had done was the replacement of the fuel injectors. If you just now began to have starting/cranking issues, my only recommendation is that you start taking it to the dealership to leave a paper trail. This was an expensive headache for me because even taking it to the dealership costs me time and money.
One of the biggest factors is that my Sienna never threw a code - And if its not throwing a code the dealership will keep trying to convince you that there's nothing wrong with it.

Yes, that makes sense. Thanks!
