Does anybody know if the electric sunroof motor in a sierra is the same as the one fitted to a Granada?

yes it is on the later ones with the finer splines

if you get the coarser splines you can still swap the turny bit over

Mine is a '92 facelift Granada so what year of sierra would I be looking for or would it just be a matter of checking the park numbers?

It is the same for early sierras.
Changes on facelift models, so approx 92 onwards.
The motors same but the cog(bit that turns)is smaller on later ones, so thats why it doesnt work. I think if u have the bits handy u can change the cog?

Hope this help =)

Sorry forgot to point out, sierra one changes on facelift cars, not shure if the granada one changed also, tho i would presume it did???

ok???
I think from the info above....
A pre 92 motor from a granada fits a pre facelift(87-91) sierra and post 92 granada motor fits facelift(92onwards) sierra!!

you just need to make sure that you get everything from the granada/sierra donor as most folk forget the panel the motor bolts to

the earlier sierra's also don't have enough space to fit the motor into so you need to chop a bit out

also you need to run the power via the electric window loom as you don't want to be running it from the lighting circuit so you'll need to fish out the wires through the a pillar

one more thing, i don't recal sierra's other than 92 spec onwards having electric roofs

Yes i beleive you are right.
Looking back at my post what i meant is...!!! the spindal/winder/cog in the roof of the sierra(the bit the motor turns) changed.

Best pic I can find but the fine splines are just about noticeable here.



I know nothing about the Granada, but the Sierra sunroof changed to fine teeth with the swoopy dash, so in 1991. Not sure if there were electric sunroofs in the Sierra before that, but I took the cog from a Granada motor to make mine work. However, it is as slow as sin and it won't pop the roof up at all, even after greasing the winding cables so open to any helpful tips.

Mine does this, so i'm thinking the cog is broke

Taking into account the motor and splines are fine, try checking the bolts that hold the motor on are not too tight. I had to fine tune mines until i found a point when it all worked in one smooth motion.

it's all good here mate

now there are some pics up it should be much easier to explain

the winders on the 89/90 soec cars have corse/fine splines so you need to find out the splines you need to match up to your car first

you can then get the bits you need, i've got 3 motors in my garage just doing nothing if you want bits (just got to find them)

for those who have sticking glass, it may be that the actual glass is jammed if it doesn't go up, pop the glass out of the appeture by winding it back and then clean the metalwork around where the roof and glass panel meet, especially at the rear, as this is what normally causes it

One more thing to check is the rubber seal that goes around the glass.
At the back is where the join is (u can see it from the outside), over time it can swell, manually it still works as u can put more force on it.
Try pushing the back of the glass up from inside and down from outside while pressing the button in the appropriate direction.
