Thanks Ian! Very nice.

Is it wrong to lust over another man's sunroof?

Chuck:
I understand that you have other issues on your car which you are dealing with. You appear to have made a good job of sorting that damaged ignition amplifier plug and good luck with the other issues.

My sunroof was working when I acquired the car but it had deteriorated since then but I was fortunate in that I was able to obtain the required replacement parts to rejuvenate it.

I apologise for the quality of my images which were obtained using my ancient Nokia 'phone but hopefully, together with previous images and you recent ones they will be adequate.

I see from your images in post 48 that the "short rods" have broken away from the Selector Gate fitting. Having seen the Skandix image of the Selector Gate I'm surprised that the short rod is sold as part of the Selector Gate . I would have expected it to be listed as a separate item. But that could explain why it is not itemised in the volvopartswebstore (VPWS) exploded diagram. The Selector Gates are handed and listed as part numbers 3503788 (left) and 3503789 (right).

When I was replacing my sunroof seal and wind deflector I dia not examine the Selector Gate are closely, hence my thoughts about how your pieces should fit together were a little off the mark. I have since had a closer look at mine. I note that what I referred to as "bobbin" on the end of the short tube is in fact a spring cli, presumably meant to secure the short tube onto that projection from the Selector Gate assembly.











I was loathe to dismantle my mechanism or remove the sunroof again bit I suspect that it may be possible to see more clearly with the sunroof panel removed. I see that the light coloured "cranked" arm appears to consist of two parallel pieces and incorporates that projection which that short rod was located on but which has now broken. The lower ends are attached to the "Sliding Block" (item 5 on VPWS ) by a pin which I cannot see itemised on the VPWS exploded diagram. It may be supplied with the Selector Gate assembly. The upper ends of that "cranked arm" have two pins which locate through the slot on the Selector Gate and are secured by the "Washer" and a clip termed a "Lock Washer" ( items 9 & 10 ). If, as it appears, the Selector Gate is supplied with these parts alreadyh attached then it appears tha the only connection between the Selector Gate and the Sliding Block is that pin through the lower end of the "cranked arm". Quite how that is fitted and secured I do not know but it may be obvious when the sunroof panel is removed and the Sliding Block is more visible. Given that that arm assembly only appears to be secured to the Selector Gate by the pins in the slot and to the Sliding Block by a pin, if a damaged sunroof could be obtained it may be possible to salvage that separate arm and short rod from the Selector Gate assembly and fit it to yours, or even salvage the complete Selector Gate assembly.

The following images show how the rectangular steel frames are attached to the rear underside of the sunroof panel itself. The frames could be item 31 on the VPWS diagram but are listed as a "spring". The spring itself could be item 32 which is also listed as a spring.








Is there anyone reading this who may have such a damaged beyond repair sunroof assembly from which the required items could be harvested?

Thanks for the pictures and detailed info Ian. Between your info and a little common sense/trial and error I should be able to figure it out.

The engine is running pretty decent. My only complaint is it takes a minute or so to idle on start up. I am getting a 1-2-2 error on bank B, pin number two which is probably related. "Signal missing or faulty to/from air temperature sensor". I'm not sure which sensor it refers to.

I took it on a short road trip it. It runs/rides pretty smooth considering the bad tires. I couldn't go far as I have not registered it yet and have no tag/insurance.

I next need to tackle the non operational air conditioner and if I accomplish that I will purchase some new tires. After this I will move on to the sun roof, but who knows.. when the seal arrives, I might just pull it inside and work on it.

Probably the one in the dome light for the A/C system. The engine doesn't have one!

Well then, how do you get rid of this 1-2-2 error? Do all 940 throw out this error code, in other words, is this normal??

I tried two procedures for clearing it

1 disconnect battery, and reconnected, still there.

2 Hold button for 5 seconds etc..

and it still will not go away.

EDIT---------------

I realized that I should not have posted this here since this is talk about sunroofs.

You need to find and either reconnect or renew the air temperature sensor on the heater blower/fan unit. Code1-2-2 does NOT exist for the LH2.4 injection system :

https://www.volvoclub.org.uk/faq/Eng...InjectionFault

However it does for the A/C system :

https://www.volvoclub.org.uk/faq/Hea...iagnosticCodes

It is possible you've misread the code and it's on the engine/LH2.4 system and is in fact 2-1-2 but you'd get the EML/MIL/"Lambda" warning light on the instrument cluster coming up if that was the case.

Have a read of the info in both those links and make sure you're accessing the LH2.4 system and double-check the code, if not check the A/C system and thatair temp sensor mounted in the fan housing area.

Between Ian (Ian21401) and myself we have put together pictures of a 700 and 900 series steel sunroof. This is primarily to help with a photographic comparison between the two, help assess the similarity and the compatibility of parts that are available for each. After all, pictures speak so much louder than words sometimes. I get confused about the suitability of the parts for my 740 hence this little exercise. Thanks Ian.

Pictures are attached from the following aspects, the Front Left and Right of Sunroof, the tilt mechanism at the rear of the sunroof and the seal from the rear left side in the tilt position.
In each picture, the 700 is on the left (Red car) and the 900 is on the right (Silver car).

This is thread ‘sunroof / moonroof reseal’ started by aardvarkash10 on May 02, 2020, thanks to you for that. There is also another great thread called ‘Sunroof Wind Deflector’. which I attach a link to here.

I hope you find this useful.

I got my sunroof seal in. I am impressed with the company I bought it from, Scandcar. They automatically took care of my Paypal error without any communication They saw that I had paid three times and gave me a refund. Prompt shipping too. From the Netherlands to South Florida in one week... not bad. It was not available in the U.S.

Genuine Volvo:



Here is a blurry end view. It measured 111 5/8 Inches (295.275 MM) in length:



Next chance I get, I will try to install it.

Excelent service!

When you come to fit it, try and "bunch it up" as tight as possible (a rubber mallet to dress it towards the bit you've already fitted helps) so that if/when it shrinks in service, it's still long enough to reach. You'll be surprised how much you can get on that way.
