Sun Roof Switch

Tatnic · Post by **Tatnic** » 28 May 2009, 11:20

I have a problem with the sun roof. It doesn't open and close automatically. It opens and closes but only if I hold down the button. This is not so terrible, but I have to stand outside the car while tapping the button so it closes tightly against the rubber gasket. Sometimes it takes a few tries. Again, I don't mind this but this is suppose to be my daughter's car and I would prefer that it work as it did originally, which I assume was automatically closing at the right position to provide a water-tight seal against the rubber gasket. Is the switch bad? How hard is it to replace this switch and what is it called exactly? thanks for your help.

On mine it doesn't work that way. To open it I can either push the switch back and hold it or push it some more and it goes into automatic open mode and opens all the way. It doesn't automatically close - I have to hold the button forward. I assume this is a safety feature so heads, arms, torsos, etc. don't get accidentally trapped in the sunroof.

When I close the roof and keep holding the button it goes into the tilt position-- I have to let go of the button just right to avoid that. Are you saying you don't have that problem? I may be doing something wrong--no owner's manual so I'm in the dark.

Yes. On mine you push the switch forward to close the sunroof. Then you have to push the switch upward to go into the tilt position. I'll see if I can find your owner's manual for you.

Here's a link to your owner's manual online: https://www.customers.volvocars.com/own ... v40_00.htm

Here's what it says about the sunroof operation:

Electrically operated sun roof
The ignition key must be in position II. The sunroof has an "AUTO OPEN" function. Press the left side of the toggle switch once, briefly, and release to automatically open the sun roof to the driving position. The driving position reduces rumbling wind noise. Press and hold the switch to open it the rest of the way (fully open position).

pg. 51 Sun roof (option)

Ventilation position (A)
Press the button (1) shortly once on the right-hand side to open the sunroof to maximum ventilation.
If you press the button again on the left- or right-hand side then the sunroof will stop.
The left-hand side of the button must be pressed and held to close the sunroof completely.

Sliding position (B) Press the button (1) shortly once on the left-hand side to open the sunroof . The sunroof will stop in the "driving position" (*). Press and hold the button again on the left-hand side and the sunroof will slide to fully open position(**). During sliding, the sunroof will stop by pressing the button again on the left-or right-hand side.
The right-hand side of the button must be pressed and held to close the sunroof completely.

(*) Driving position : A position where the sunroof is not fully open. This is to alleviate 'booming noise' during driving.

(**) Fully open position : This position is not recommended while driving.

NB: Do not close the sunscreen with the sunroof open. This may prevent it working properly.

Sunscreen The sunroof also comes with a manually operated sunscreen. This automatically opens with the sunroof. WARNING!
The sun roof must never be obstructed in any way when in operation.
* A position where the sun roof is not quite fully open. This position helps alleviate "rumbling" wind noise.

See page 98 for instructions on manually closing the sun roof.
