Hello everyone! Hope you all are doing well.

This is what's happening to my 2002 Freelander sunroof, I took it appart because I lubricated the guides and everything. When I put everything back on, it tilts and opens fine and it stops on the fully open position, the way it's supposed to be, but when it comes to closing it, when it reaches the fully closed position the motor just won't stop working, it only stops if I depress the button, which is a pain in the butt because I have to keep an eye on the glass everytime I close it and I was wondering if anyone could help me with that.

I've read as many posts as I could looking for an answer but I didn't have any luck.

By the way, I've read that many posts are about the sunroof jamming or making the click kind of sound when working, it happened to me once and I took the motor appart and discovered that the main plastic gear wears out and needs to be replaced, there is a place here where you can have it custom made. After you replace it, it works smoothly.

Thanks a lot.

Hello teddywood1, no luck for me, the only things I can see are the relay box and the sunroof main relay in the fuse box. Any other suggestions? Thanks a lot!
 
I took it apart and I only saw a few capacitors, but that's it. I find it very strange that the sunroof will open fine and stop where it's supposed to, and then when I try to close the sunroof,simply won't stop working where it has to.
 
Hi - Rave manual says to ensure motor and lifting assemblies are timed together:


Fit motor - fit lucas connectors, not multi-plug.
Open to full tilt. NO FURTHER.
Remove motor from assembly, but connect multi-plug (leave lucas connectors on).
Keep switch on 'open' until motor stops.
Refit to assembly.

Hope this helps !

Hello Andrew, thanks a lot for your tip. I checked that and I still have the same problem, the sunroof opens fine, but when it comes to closing it, the motor just won't stop...
 
Been looking at this one, was puzzled about how the sunroof is supposed to stop and how motor is controlled. Have taken mine to bits and drawn circuits and worked it all out now !!!

The small box near the motor houses 2 relays and a diode and 2 resistors. The motor has a rotary switch on it that is designed to cut power when 'tilt' is achieved. This works, as my entry above, when correct alignment of motor to mechanism is achieved.

However, with regard to stopping the motor at either end of travel - the Landie design is very poor, it relies on stalling the motor (which then draws about 9 amps). When the switch is pressed at either end of travel the motor is being held by the mech with power on it. The clicking is the motor rotating against the drive cables and 'jumping' as described by others above. Only solution once this has happened (as the motor cog quickly wears the cable out) is to replace the drive cables. I am designing a simple current limiting device for mine to plug in so that at the end of travel the current is limited and also if the mech jams it doesn't self destruct due to the power of the motor - which is very very powerful indeed. Sorry it is not an easy one, but at least I understand how the thing works no. There are no microswitches in the mech, only the rotary one in the motor that cuts power when opening about every 13 turns of the motor. As the full movement of the roof is less tan 13 turns it only occurs once, intended to align with TILT. The diode means that when closing the motor does not get cut and the close movement is in one go. Cheers
 
Please see my sketch of circuit. The relay box mounted near the motor is not shown in Haynes or Rave diagrams. If anyone needs an explanation of how it works, please ask.

Cheers, Andrew

Might be worth making the circuit and description a sticky - many have questioned the operation of the sunroof and gone off talking about microswitches and the like !!! Dunno how to do it though !!! Also - the circuit is a bit of a work of art - don't ya think.
 
Sorry, still a little confused. Are you saying that the [power to the motor is stopped on a timer that effectively "times" 13 turns ? Or that there is an over-current sensing device that when the motor "stalls" due to getting to the end of the roof travel, goes over-current and power is removed ? confused.com ebt
 
Sorry if not clear. The motor is cut as the roof opens by a rotary contact in the motor. If the motor is in sync with the mech (as per the RAVE set up, i.e. open roof to tilt, drop motor, run motor till it stops, refit motor) then the roof will stop at tilt. A second press of the button will motor the roof right back and then the full force of the motor and 9.5 Amps will flow as the motor forces the against the stops. When the close button is presses the roof moves without pausing at tilt to close fully. Once again the full force of the motor causes the mech to hit the close position. Any 'clicking' heard is the motor wheel teeth slipping on the cable (which is actually a rack). I am making a current limiter as an 'add on' to prevent damage. Hope this is clear. Interesting, but pants design !
 
Also - The 13 times is not relevent to operation. It is just that with the motor removed it runs 13 turns until the TILT position is reached again. Hence with the overall operation from close to open less than 13 turns it only occurs where it is in sync with tilt. Assuming set up correctly.

Hi Andrew,

Did you ever make this circuit relay ?

Regards Ric
 
Hi Ric, I didn't intend to make the circuit, I simply drew out what was fitted to the car in a box up in the light case overhead. Hopefully the diagram helps you to understand it. I couldn't find it drawn anywhere in Rave so drew it on a wet afternoon when I had nothing else to do - not a common event !!!

Cheers

Hello [again?] Andrew,
I have been following, with belated interest, the sunroof saga and have found that your investigation and logical approach far outweigh the more bizarre "try this" offerings.
To get to the point, I now have a fully working sunroof which does as it's told - except on closure. [This is where it all started!] I have looked at your wiring diagram with all the knowledge and authority of someone who is better informed but none the wiser - a reflexion on my brain power and not your explanation. Of the black box: is it that one of the contained relays cuts the motor at the end of OPEN travel and the other does the honours at the end of CLOSE travel? If so, it seems to me that the renting of garments and gnashing of teeth could be eliminated by renewing the black box,
However, if I have misinterpreted the functions of the two "black box" relays, then we are back to Square One and keeping a weather-eye on the roof panel as it shuts.
I appreciate that this is an old chestnut and that you may be bored by its resurrection, but if you have the time to comment on my hypothesis, I would be grateful.
Kind regards,
Patrick C

Hi Andy i have exactly the same problem with my sunroof motor when closing i can see the drawing makes sense of it but have you any further info on how and what i need to stop this fault, cheers m8
