[xj] Sunroof motor feeling a little grumpy

While driving down the freeway I decided to open the sunroof
on my 82 SIII XJ6. After opening about halfway, it suddenly
quit. I tried repeatedly to open or close it and it just
wouldn’t move. I checked the fuses first thing when I got
home and there were none burnt. I then checked the roof
itself to see if maybe it had jammed on something in the
track, but there was nothing. Finally, it was getting late,
so I climbed in the trunk with my trusty wrench and spent
the next 20 mins shutting the sunroof.

In the morning, I tried the sunroof again (hoping it had
slept well), but it still didn’t work. I decided that I
probably needed a new motor and I didn’t touch the sunroof
controls for a week. Then the other day, while driving home
from work, I wasn’t looking at which window buttons I was
pressing and I accidently pressed the sunroof button.
Suprisingly, it began to open! I quickly shut it, fearing
anoher heart-warming evening in the trunk with a flashlight
in my mouth. I haven’t even begun to ascertain why the motor
did this. My guess would be a short in the system or faulty
wiring, but that doesn’t seem right, seeing as how it worked
perfectly before. I’m baffled and my patience with the
electrical system is being used up by the radio right now.
If anyone can help, that would be pretty awesome. I’d hate
to miss these summer driving days!

I’m guessing the switch needs attention. It’s the exact
same switch as the ones for the windows, that famously stop
working at the worst possible time, but merely need to be
opened up, cleaned/burnished, and reassembled to work again
for another 10 or 20 years.

Ryan,

It is probably “not” the sunroof motor at all!It is
most likely a dirty sunroof switch . Carefully remove
the sunroof switch and clean the copper contacts with
some sandpaper. Don’t lose the little springs inside
of it when you dismantle the switch.

Just because we are forever being advised to “clean the contacts,” don’t be
tempted to think this is unique to Jaguar, or even Lucas. With a weather
forecast of 100�F for today, I found I had a dead electric motor in my shop
cooler. Opened the motor and found all of the windings good, so I gave the
contacts on the starter switch a good treatment with 400 grit. All is well.
I did Jag work all day in perfect comfort.

Coincidence! I spent an hour yesterday afternoon getting the
sunroof motor out to investigate near identical symptoms to yours.

In my case it turns out that the nylon gear wheel which is driven
by the motor has a split in it. Under load this appears to jam on
the motor drive. I am waiting for a new wheel to arrive (�6 UK) to
see if this fixes the problem.–

On my 83 111, there is an off-on switch above the sunroof switch.
It seems to control power to my sunroof switch. My roof wont
operate if this switch is not in correct position. I do not have
handbook yet so do not know its purpose. It may control door locks
power also. My wife was much happier (me too) when I suggested she
check this switch via long distance phone call. FWIW LeroyR–

That’s the window switch lockout control (to keep the little
kids in the back seat from running their windows up and down
after you told them not to, etc.) I didn’t think that was
supposed to also control the sunroof switch, but I could be
wrong…–

Dave:

No! the small on/off switch above the roof switch IS the window and
sunroof lock switch. It does not control the rear windows alone; it
controls ALL the windows and the sunroof.

Doesnt control it on my 85 VDP. Don’t know if Jag made a change, I
can’t imagine why they would lock out the sunroof being that the
sunroof controls are right next to the lockout.–

Not any more than it makes sense that they would lock out
the driver’s window switch with those switches right near
each other, but I know it does that! I had just never tried
it with the sunroof switch. Sounds like it is indeed a
master lockout.–

Dave, I’d guess that a PO made the change on your car. As shown in the S57
and other wiring diagrams, the switch in question locked all windows and the
sunroof on all the Series III cars, as it did on my 1987 XJ6, at least up
until I bypassed it and set up the switch for the Gardiner mod.

I agree. The windows and sunroof operate off the same relay. The control
side of that relay is grounded (or un-grounded) via the lockout switch.
