How can you lock in the four wheel drive on a 95 dodge ram when actuator stops working?

The actuator failure on a 1995 Dodge Ram's four-wheel-drive system prevents electronic engagement. There's no way to "lock in" the four-wheel drive electronically if the actuator is malfunctioning. Attempting to force engagement without a functioning actuator could seriously damage the transfer case or other drivetrain components.

Your options are:

1. Repair or Replace the Actuator: This is the proper solution. You'll need to diagnose the specific actuator problem (electrical, mechanical, etc.) and either repair it (if possible) or replace it with a new or used actuator.

2. Manual Engagement (If Applicable): Some 1995 Dodge Rams *might* have a manual lever or shift option for 4WD low. However, this isn't standard on all models, and it depends on the specific transfer case. Check your owner's manual to see if your truck has a manual override. Even if it does, forcing it when the actuator is faulty is still risky.

3. Towing: If you're stuck, your best bet is to have your truck towed to a mechanic or repair shop. Attempting to drive in 4WD with a bad actuator is likely to cause further damage.

In short: Don't try to force it. Get the actuator fixed. Forcing the system could cause expensive repairs to the transfer case, axles, or other parts. A qualified mechanic is your best resource for diagnosis and repair.
