S40 Sunroof Issue? Won't open but motor is going?
Hey guys.
Went to look at a used S40 R Design today, absolutely lovely car but the only main flaw was that the sunroof doesn't seem to want to open? Pressing the button forward or back, the motor can be heard whiring away but it won't budge. Any ideas what this might be? Stripped cogs? Broken...something? Another thing...The seller said he'd had the immobilizer updated and the battery replaced...could this be the issue or does that sound like more problems lurking underneath someplace? |
Suspect the teeth are stripped on the plastic gears in the sunroof mechanism. Likely an expensive fix.
"Immobilizer updated" sounds odd. You can have the car's ECU and software modules updated at a Volvo dealer but that particular language used by the seller sounds strange. Personally I would say that if you want a working sunroof, walk and look elsewhere. |
Even if a working sunroof doesn't interest, a non working one will be a pain when the drain holes eventually block and start leaking into the car.

Back on the sunroof...surely not that water much would be able to leak or get in when the sunroof is sealed shut? Looking at it, it was sealed up pretty tight it seems.
From what I've seen, unclogging the drains could be done with the sunroof closed anyway, am I right? Pull off a pillar trim, disconnect piping and blow out/clean the piping? Not ideal, but possible? |
as the drains clog up With the roof closed, it will matter
as the roof wont open, you wont be able to clean out the debris In there, which clog the drains up or pour water directly into them to flush out the bits in the pipe when you have taken the A pillar trims off delt with the stupid elbow and POS thing on the end of the pipe,, the CEM will get wet / soaked, the front foot well carpets will be soaked, the CEM will give you all sorts of electrical issues with the car, cause multi random error messages and dtc's stored potentially costing you £££££££ replacing the parts allegedly faulty, ,,, as for the "Immobilizer updated" bullshtit its there its a factory fit item , end of if it unless the car is 100% perfect other than the Very costly sunroof gear mech and motor And the price reflects that , dont Walk away RUN away |
Going to go out and guess that there's no way to manually open or close the sunroof? I see that the motor is behind the courtesy light panel there, but I don't know if it's similar to the older s40s that had a slot for a flat head screwdriver.
I guess worse comes to worst, If it started leaking I could remove the glass and get access to the drains that way? Think it's just four screws that hold it in. Thanks for the replies guys. |
