Weird. Even if the light goes off usually those codes are still stored in the vehicle. Did they do anything to look around and check for damaged wiring or anything like that or give you any suggestions as to what the problem might be?

Be very careful. You're right, most likely not water from a crack but a bad install of the front glass. This is a notorious spot for water to get in and leak down the A pillar. If they already fixed it great, but if they just repaired the connector and did not address why it happened, it will come back again.

Water leaks are usually not huge and take time to get into those JB boxes and do damage. No, corrosion does not usually happen overnight. But if you had one night of heavy rain, water could get in and cause those problems, then continue to corrode over the next few months.
Its usually pretty easy to check for leaks if you dont mind doing a bit of work yourself. And I prefer to find the issue myself rather than trusting whoever did it in the first place. Of course they're going to tell you they didnt find anything right.
Pull off the A pillar garnish and get someone to stand outside the vehicle with a garden hose and run it full blast on the glass from the outside. You dont need so much high pressure but high volume so its just pouring down. Get inside the vehicle with a very bright light and be patient. Sometimes the drip can be very slow to start, or difficult to see.
Usually the cause is the bead of urethane sealant that was applied to the glass before it was installed was damaged in some way. So rather than being a nice consistent thick bead of sealant its wiped flat, not applied at all etc.
Its just odd that you had it once, fairly soon after your issue, and you havent had it again, so maybe it was fixed, but it sure doesnt sound like it.
Good luck and post back if you find any issues.

Every company is going to have complaints against it, you just need to make sure your glass isnt leaking. If you are not comfortable pulling the A pillar and poking around yourself you have 2 options.
Take it back where you had it done and make them check, but if they screwed up are they going to actually find it and own up to a mistake?
Or call some other places, explain what issues you've been having, and ask them if they could check for leaks. Some dont want to touch jobs that other places have done, but thats why you call around and ask.

Sorry, I am sort of confused. You had a cracked windshield, water got in and corroded the connector, but the glass has since been replaced right? Just your sentence that says they pointed out water in the crack in the new shield.
So does that mean you have a cracked windshield again?

Wow, you've had some seriously shit luck thats for sure.
I'm no expert on what is good and no good when it comes to cracked glass and what will or wont cause electrical problems. It does seem to make sense what they said though, and your pictures seem to support this. A vertical crack allowed water inside the passenger compartment and wreaked havoc on your electrical. I never would have thought that was possible but it sure does sound logical. Your most recent broken glass looks like the crack is mostly horizontal and runs along the bottom of the glass.

Does the crack dip down just below the wipers and take 90 degree turn so to speak or does it stay horizontal?
Again, never heard of this before but my point is, if the crack runs downward toward the dash again, wouldnt you be at risk for the exact same type of water intrusion you had before?
If yes, maybe go to a glass repair shop and ask them to fill it with that gel hardener stuff they use on small chips. Idea being just to make sure you dont get that same water leak idea.
Either that or you might need new glass again.

If glass cracks it has to start somewhere and there's usually 2 ways it happens.
Something like a stone flies up and hits the glass while you're driving, then it spiders outward. You can usually see a chip or crater where that started and usually in the middle of the glass.
The other way is the edge of the glass. It can be made defectively or get hit on the edge. You can very lightly hit the edge of a piece of glass, take a chip out of it, and watch it spider pretty easily.
Is that picture you have in post 45 your current damaged glass? If yes, where did the crack start, at the middle or the edge?
If you say middle, you're probably up shits creek and you're going to be told a rock did it.
If its the edge of the glass you have a slightly better chance of getting them to eat it. But even if its an edge crack, they're probably going to say it didnt leave their shop cracked and tell you to pound sand.
Either way, if you had the glass installed at Billy Bobs House of Windshields, Bait and Tackle, do you really want to go back there?
If you dont want to go back to Billy Bobs, and cant really afford to fix it right away, you can buy some DIY repair kit for now. Its basically crazy glue you just fill in the crack with for the short term.
Just google windshield crack repair.

So the third picture in that post, the one that says 09.jpg, shows it as a straight vertical crack right?
If thats your current glass that looks like pretty big crater just above the wiper and the crack went up and down from that starting point. If thats true then no way does that look like whoever installed it caused that chip. Looks like a stone chip that spidered to me.
Maybe not what you want to hear but thats my guess.
Either way get some of that glue and fill the crack till you can get it fixed.

Not at all trying to be an A hole but this just doesnt make sense. I had to go back a page to see your leak. You had corrosion in DA4, which is RH JB box located inside the passenger compartment. I just dont understand how water got from the bottom side of a windshield, in the engine compartment, to the inside of the passenger compartment, on the passenger side, into the JB box where your passengers right foot is.
Not saying you didnt have a problem, I just dont understand how water could physically travel a path like this.

If you want to know if you have heated glass see this thread by Geezer. Apparently all Sienna's should have it.

Is your head sore from beating it against the wall dealing with these morons yet? LOL.
One thing to keep in mind, that thread from Geezer says all Siennas come with heated front glass. Read it to make sure you understand it and if thats true, make sure the glass they put in your van is heated. I think he said you can test this by pushing the rear defrost button and you should feel heat just under the front wipers.

The fluid is probably just washer fluid. The jets are on your hood so when you opened it gravity allowed a bit to leak out, nothing to worry about. Your third pic shows the drips. I bet those drips are just below the washer jet yes?
As for the wiring, that was jseyfert3 that took that picture, not me. Look at his picture again, he laid a flashlight on the cowl to shine brightly inside it and he was probably 2 inches away when he took the one picture.
If you have a bright flashlight, shine it directly in the cowl like he did and get your face right in there. You should be able to see the wires if they're in there.

Dealing with shady businesses is awesome isnt it.
I did just go check mine and I do also have heated glass. Never even knew I had it. Thanks to jseyfert3 for suggesting just shining the light in there. That never would have crossed my mind.
It does kind of suck you have to hit the rear defrost to activate it though. Lots if times there's ice build up on the front as you're driving into crap weather and the back can be clear and not need heat. My wifes 2021 Rav has a button to activate just the heat up front, wish mine was like that.

I just tried mine for the first time the other day. Wasnt super cold out but maybe hovering around freezing. I am sure it was slightly warmer under the wipers where I think the wires should be, but definitely not warm in any way. Supposed to get cold this week for the first time all winter here, maybe will try again and see if it does much but so far I cant really say I'm impressed in anyway at all.
