Hi Chaps,

My trouble started as an intermittent fault particularly in warmer weather but has gotten worse to the point where it generally doesn't work.

When I hit the switch I can hear what I assume is the relay clicking in the roof liner near the main cabin light.

Giving the roof liner a thump with my fist got it going again a few times.

Based on advice given it's most likely either a dry joint somewhere between relay and motor, or the brushes in the motor are gone.

Question 1 has anyone else had this and got a suggestion?

Question 2 how do I go about getting the roof liner out neatly?

Keen to hear of nice way to get roof lining out as well.

I had my back sunroof stop working for a while, but then it fixed itself.

I have a spare motor for the back (same as front?) in a box plus a wreck with sunroofs that I can strip out if needed.

Finally got off my arse and removed the headliner, thanks Andrew from Muscle Motor Trimmers for some pro tips. I'm getting power up to the last plug before the motor and while holding the sunroof open switch on, if you tap the motor housing with a screwdriver it works.

This would tie in with Scott's theory that the brushes in the motor are had it. Gonna get an electrically minded relative to confirm my diagnosis then look to replace it.

Same thing has happened to my electric seat, though it's harder to reach under my seat and give the motor a tap with a screw driver whilst the seat is still bolted to the car.

Glad I have a sparky in the family, turns out the problem was dry joints on the circuit board of the relay next to the motor, invisible to the naked eye. Will post up some pics and tips for roof liner removal shortly.

Blek, got the same issue with my passenger seat electric switches cutting out, job for another day.

      After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
