both electric windows dont work?

How do everyone,

Im pretty new to the site and just bought my first land rover, and both of my lecky sunroofs dont work which i knew about when i bought it but thought i would have a go at fixing them so here i am asking for advice and to see where to start if anyone could give us any advice that would be great.
Oh yeah before i forget its a discovery v8 on a 97.

Cheers Ben.

Hi Ben84
Just type in Electric windows in the search box at the top, there is a diagram showing what to do, its probably a dry joint on the board behind the glove box.

soory mate im an idiot put windows instead of sunroof i have changed the description
sorry again

As stated the the window ecu can give problems have look at this link. Repair a Land Rover Discovery electric window ECU to make the rear windows open again.

cheers discool this seems helpful gonna have a go at it tomorrow hope it works cheers again

Got the ecu out which was hard work.The only thing is i dont know what a dry joint looks like any advice anyone.
Cheers Ben.

1.This is a good joint with a smooth shiny appearance.
2. There is not enough solder on this joint.
3. This is a 'cold' joint with a rough, dull crystalline appearance. This is caused by moving the joint as it is cooling or by taking solder to the joint on the soldering iron.
4. This is a 'dry joint' where the solder has not flowed onto the PCB track.
5. This is a solder bridge onto an adjacent track. This board has a green 'solder resist' coating on the tracks. The solder resist may prevent a short circuit but even so, solder bridges like this should be avoided.

What if they have spikes on them i take it these are fine the odd one feels blunt sorry for being abit thick

the spike is just the leg of the component, no worries with that... main worry is any gaps around that spike or round the solder as it touches the board

The board is generaly green but the odd solder you can see abit of yellow should the solder cover that as well other than that the ecu looks fine compared with your diagram.
Cheers again Ben

there are no gaps or anything either looks good to me.

Ive gone over the hole ECU and both electric sunroofs are still not working.Is there any more ideas that would be great.
Cheers again Ben.

can any one help ive changed the fuse ive checked the ECU and still nothing im lost any help please?

Hi ben84,
The problem could be in your control unit, which serves both sunroofs, and is fitted above the front switches and benind the headlining, to get it out and check it you will have to do as listed below.
1.Disconnect battery neg. terminal
2.ensure sunroof is in closed position
3.remove switch panel from stowage pocket
4.remove interior lamp from stowage pocket
5.remove alarm ultrasonic unit
6.unscrew 10 fixings and remove stowage pocket from headlining
7.disconnect electric plugs from control unit
8.remove 2 retaining screws and control unit.
Check it out with a multi meter or have it checked by an auto elec. make sure there is power to the switches, if so the chances are its the control unit.

Hope this helps

Cheers mate gonna get on with that hope it works to.
Cheers Ben

Hi Ben84,
Forgot to say you can open / close the sunroofs with an allan key put into the spindle of the motor, but make sure they are in the closed position before you remove the motor and don't turn it when the motor in off, or the park position will be different.

Cheers.

cheers mate got the ECU unit out just need to get it checked out and see whats goin wrong let you know how i get on.

Hope this helped and hope you get it sorted out, if there is power to the ecu then it can only be the ecu, the motors or the linkage on the rails at fault ( i think)

Cheers

still havent got the sunroofs sorted.i was getting no reading from the switches so went down to the fuse box replaced the fuse any way still nothing gave it a wiggle and i got power to the switches but still nothing happened but then the other day turned the key and the front sunroof opened up by it self i could close it with the switch but then nothing how crazy is that.oh and the rear one i think the motor may have gone
