Have you accidentally broken the connection to your recovery boots?
You can easily replace it yourself by buying a new one and pulling out the old one. It is important that you connect the new one in the same direction so that the air goes from the bottom up to your boots.
The connector is easy to install on the hose.
Fits the following models (NOT CHARGE):
Recovery Boots K4
