Does blowing air through either side solve the problem or do I need to replace the solenoid?

If your solenoid doesn't pump air then you have to replace it. Blowing air to it just to test to see the fork actually moving to engage or not only.

Hello from mexico Sr! I have a problem with my 4runner 4wd limited 96. Automatic transmission. the 4wd does not disengage, the car only moves if it is in 4L or 4H if I put the 4wd transfer in Neutral, the 2WD doesnt work and it does not move in reverse or drive and the red light comes on of the A/T P in the cluster. can you help me? Im going to try check the vacum lines but could you help me! Probably you had the same problem before! I really apreciate your help and expirience!

If your 4runner have engine light use obd2 to scan for code to fix it. It's sound like bad transmission but not sure why when you put in 4wd it can move but not 2wd. First thing is scan for code then fix the code problem. Can not be blindfold to fix car doesn't work that way always scan for code to do troubleshooting ok.

The 4WD would engage (solid green light) but to disengage after pressing the button the green light stay solid nothing happens right away but later after driving awhile there would be a BIG bang (shakes the car) and it disengages. Any recommendation on what to test?
