A hidden arm is not a stuck arm
On many cars the wipers park partly beneath the rear edge of the bonnet. That can make a familiar blade change unexpectedly awkward. Pulling harder is not the answer: the arm may strike painted metal before it can rise, damaging either part. Look up wiper maintenance or service position in the owner’s manual before touching the arms. The correct procedure varies with the car’s control system.
Some vehicles use a sequence involving the ignition and wiper stalk; others provide a screen menu. A procedure from a similar-looking car may not apply. Park securely, ensure the glass is free of ice and keep hands away from the sweep area while commanding the movement. If the arms do not move as described, stop and recheck the instructions instead of experimenting with the controls while holding a blade.
Prepare before lifting anything
Have the correct replacement blades ready and understand their connector before removing the old ones. Front blades can differ in length, and the rear uses its own arrangement. Protect the glass as the fitting instructions recommend and keep control of the sprung arm. Never leave a bare arm standing unsupported while you search for a part in the house.
When cleaning rather than replacing, lift only as far as the vehicle instructions allow. Do not bend the arm to obtain more access or pull on washer tubing attached to a blade. Some systems have integrated jets or other fittings that change the procedure. If access remains awkward, a workshop can complete a small job without the risk of a cracked windscreen.
Return the system deliberately
Lower the completed assemblies carefully onto the glass before leaving service mode. Then follow the prescribed return procedure. Activating the motor while an arm remains raised can make it strike the bonnet or another component. Check that both blades are secured, sit correctly and clear the glass on a wet test before considering the job finished.
Save the manual page or bookmark the instructions if this is a task you repeat seasonally. The position is a maintenance aid, not evidence of a fault and not necessarily a winter parking recommendation. Use it for the purpose described by the manufacturer, rather than assuming that leaving the arms raised indefinitely is always beneficial.
