Air Suspension stuck - Airbags completely inflated

Hey Guys,

Needed some quick advice!
Passenger side position height sensor had broken bracket so got the entire assembly replaced including the link arm. The next day the rear started to raise (ride height level I guess) but this time it was so high that the front is in nose dive position. Very odd. Has never happened before. If I try to lower its using the height select button the Lo indicator would start blinking (normal) but won’t lower, instead the indicator will go back to Normal mode and the pump would kick in. As I tried this several times, the rear air bags are completely filled and would not lower. The vehicle is stuck at home. Need urgent HELP pls!! Have tried manual mode but nothing. The rear end (height diff bw the vehicle and the tire) is about 12”-15”higher versus 4-5” which is very concerning. The airbags seems to be fully inflated.

Is it something to do with the height sensor alignment?
