I do not think that there is a front axle disconnect. If there is then it is vacuum controlled and the problem is either a switch or a broken line.

The prefix of "engaged" is "en-".
The QUADRA DRIVE is a full time system that is always engauged. It wouldn't move otherwise.
disengage
Because both axles are powered. You have what's known as a 6x4 truck.. the driveshaft comes off the transmission tail shaft, and it goes into the interaxle differential pinion. That interaxle differential provides torque to both axles at all times - not just when the interaxle differential lock (sometimes referred to as a 'power divider lock') is engaged. Locking the interaxle differential simply locks it to ensure that outputs to both axles rotate at the same speed.
The actuator on a 4-wheel drive allows the vehicle to shift into 4-wheel drive with the push of a button or a shift of a lever. The actuator allows the front axle to become engaged.
It sounds like you need a new actuator. there is two things that lock in when you use 4x4. one is the transfer case and the other is the front diff. the front diff is turned on by an actuator. if you have a problem with the actuator the front axles wont lock in. even though the transfer case is engaged.
When engaged in four wheel drive light flashes but wont engage the shaft locks but no four wheel actuator is not pushing out in my 97 tahoe?
I have read that the Sienna AWD system uses an open differential for the central differential (and I presume the front and rear as well) and relies on four wheel traction control to prevent wheel spin. It is always engaged.
The child safety lock is engaged. Disengage it on the door next to the latch.
The actuator is a vacuum driven relay that locks the front hubs when the 4 wheel drive is engaged. Failure of this part would result in the transfer case being engaged and sending power through the front shaft but the front tires would not have torque. This is a failure prone form of auto locking hubs. Used on late model Chevys Dodges and Some Cherokees. Alternatives would be a constantly locked hub set up, which consequently reduces fuel millage. Or, a manual lock system such as that used on Fords for decades.
The two most usual problems are 1- one or both of your front hubs are either bad or not engaged in the lock position. 2- check to see if you are getting power from your front driveshaft when the truck is in either 4 HI or 4 LOW. If both of these are good it is possible that you have a problem in your front differential or your transfer case.
I JUST RPLACED THE AXLE HALF SHAFT. YES IT IS ALWAYS ENGAGED. WHATS UP WITH THAT??
