Here's what's likely wrong and what you should do:
* Air Leak: The most common cause is a leak in the air spring (the bladder or bellows that holds the pressurized air). This can be a small puncture, a tear, or a failure of the seals. You won't be able to repair this yourself unless you have specialized tools and experience working with air springs.
* Internal Failure: A broken piston, valve, or other internal component could cause the shock to extend fully and remain open. This is also not something that's typically repairable at home.
Instead of attempting a DIY repair, you should:
1. Don't drive the vehicle: Driving with a failed air shock is extremely dangerous. It compromises handling, stability, and braking. You risk damaging other suspension components and potentially causing an accident.
2. Get a professional diagnosis: Take your vehicle to a qualified mechanic or a specialist who works on air suspension systems. They have the tools and expertise to diagnose the problem accurately.
3. Consider repair or replacement: Depending on the extent of the damage, the mechanic may recommend repairing the air shock (if it's economically viable) or replacing it entirely. Replacing the shock is usually more common and often more cost-effective than repair.
In summary: Trying to fix a fully extended and open air shock yourself is not advisable. It's a complex system requiring specialized knowledge and tools. Professional assistance is necessary for safety and proper repair.
