Short answer: Wiper service position stops front wipers at an accessible point during maintenance on some vehicles. If your vehicle’s manual describes this feature, follow the sequence there before changing blades or raising arms. If there is ice on the glass, first make sure the blades are no longer frozen to the glass. When finished, carefully lower the arms onto the glass, then exit service position using the method in your owner’s manual.
Why does clearance at the edge of the hood matter?
Front wipers return to the lower part of the glass in daily use. Looking from outside, the tip of the arm is visible but the path the arm travels when rising may be very close to the rear edge of the hood when in park position. The arm’s parallel movement on glass and lifting away from glass are two different movements. No problem in the first does not show sufficient clearance for the second. The point to check before maintenance is the path where the arm will be lifted, as much as where it rests.
Service position is a maintenance function used to solve this access problem. For example, the Volvo V60 manual explains that blades are brought to a more accessible location on the windshield for maintenance. When in this position, blades first stop on the glass. Do not try to grab an arm before the wipers have stopped moving. When and how to intervene with arm and blade is determined according to replacement or cleaning steps in the manual.
What information should you search for before starting the procedure?
Try front wiper, wiper blade and service position terms separately in the manual’s search field. The first result you find may only explain how the arm is used while driving. In the maintenance section, the condition you need to leave the vehicle in, command to open position, blade access and return to normal position may be given under separate headings. Read both entry and exit steps before starting work. You don’t need to leave arms in the air to search for the command when work is finished.
| Check | Information to obtain from manual |
|---|---|
| Vehicle status | What condition vehicle and wiper controls should be in for service procedure. |
| Enter position | Relevant menu or control and signal showing movement is complete. |
| Procedure scope | Whether instruction belongs to front wiper, rear wiper and which maintenance task. |
| Exit | Command to apply after arms are lowered onto glass and operations that can end position. |
A video published by the same brand for a different model or model year may help understand the access idea. Select your own vehicle manual to verify control sequence. If you cannot find the function on screen, check that you are looking at correct vehicle and manual version before randomly changing menus. If feature is not described, search for access method given in manual for blade removal. Trying another model’s command does not verify maintenance sequence for the vehicle you are in.
Work sequence when in service position
Visually inspect glass and wipers
Even if upper portion of glass appears clean at first glance, there may be ice in lower region where blade rests. If blade rubber is stuck to glass, apply vehicle’s ice removal instructions before giving service command. Do not try to free a stuck blade by pulling. After ice melts, look again at lower edge of glass and visible surface along blade. Thick ice remaining on glass is sufficient reason to postpone procedure.
Give command and wait for movement to finish
Bring vehicle to conditions specified in manual. Give service command from driver’s seat and go to windshield after blades stop. Lift to extent described by manual to access blade. If arm’s travel path appears to intersect with hood edge, stop applying force. Instead of trying to create clearance on your own by opening hood, recheck access steps and whether wipers have actually entered service position.
If blade is being replaced, verify connection separately
Service position solves arm access. Which direction blade attaches to arm and how connection locks are separate steps. Compare connection of blade you are replacing with diagram in manual and also read installation description that comes with part if available. When you cannot understand how connection is secured, do not test by operating arm. Check position and lock of seemingly attached part at connection point while wiper is still stationary.
Lower arms, then return to normal position
Return raised arms onto glass in controlled manner. Volvo requires this step to be completed before wiping, washing or rain sensor re-engages on relevant models. On some vehicles, a drive or wipe command can also end maintenance position. Therefore, if there is a second person in vehicle, tell them not to touch wiper control until outside procedure is complete. After exiting position, observe that both blades have returned to rest location described in manual.
If you suspect contact with the hood or glass
When arm approaches hood edge, do not flex arm sideways to wrap blade around edge. First bring arm to safe position in controlled manner. If you see a new mark on paint or glass, determine where it is and consult a service before applying maintenance step again. Separately describing obstacle encountered when trying to raise arm versus rubbing sound heard while blade is moving helps service understand which stage to examine.
Save maintenance instruction for next change
Add relevant page in vehicle’s manual to bookmarks or note section name in a copy you can access offline. You won’t waste time searching for step to open service position at next maintenance. Note should include vehicle’s model year, front wiper section and manual version. Also write in your own words which control ends position and where blade lowering step falls within that.
If you will have maintenance done at a service center, explain your request with scope of work. For example, if you want blades renewed, you can say to have connection and park position checked as well. If problem you observed before maintenance is with a specific blade, specify driver or passenger side. This way, instead of focusing only on spare part selection, you also address maintenance access and post-procedure position in same discussion.
Frequently asked questions
Do arms lift from glass when service position opens?
In example from Volvo V60 manual, blades stop at a more accessible place on windshield. Separating arm from glass is a separate movement made during maintenance. Examine diagram in manual for each vehicle.
Does rear wiper also move with same command?
Do not draw conclusions about rear wiper from command described for windshield. To clean or replace rear blade, open rear window section in manual. Control and connection arrangement may be described separately.
If service position won’t open, what is first check?
Check that vehicle and wiper controls are in condition specified in manual. When you see ice or another physical obstacle, first remove it safely. If command still produces no result, obtain maintenance support without forcing arms.
