Looking for help, bought a cheap Discovery 1 and not sure how the 4 wheel drive system works, the lever changes but not sure what it actually does and what the lock is for etc. I'm sure this is very basic but an explanation would help.
Also 1 of the rear passenger doors will not open and also one of the electric window is not working.
Thanks in advance.

Can't remember the different options for the gearbox. Get a manual online. I think there is even PDFs available some where.
Locks are known to be weak. You can buy new handle mechs on eBay which are better than the originals. Check all the electric windows, as they are known to fail too.
Doesn't sound like you've done much research. I wish you the best of luck!

The 4wd lever moves forward to engage low range, this gives you a lot more torque at the wheels at very low speed, but the car will top out at about 30 - 40 mph. Generally it's for off-road or low speed manoeuvring with a trailer.
Moving the lever to the left locks the front axle to the back, so you get drive at both axles in slippery conditions. It doesn't lock the axle diffs so you can still get wheel spin if one wheel on each axle has low traction.
Don't use it locked on the road, it can cause damage.

The transfer box lever knob should be marked with what looks like a figure 8.
Movement of the lever puts the tranfer box into Neutral, High ratio or Low ratio. On the right hand side the centre differential is unlocked so the front & rear propshafts can rotate at different speeds. In the left hand positions this diff is locked, meaning the props must rotate at the same speed.
In the bottom right position you are in high ratio with the centre differential unlocked. This is normal driving position.
In the bottom left position you are in High ratio & the CD is locked. Use on slippery/loose surfaces. A light should come on on the dash to show its locked.
In the middle position the transfer box is in neutral so regardless of the gear selected on the main box there is no output to the props.
In the top right position you are in Low Ratio with the CD unlocked. Useful for climbs, descents & for manouvering trailers in tight positions. I use it mainly for launch & recovery of my boat on steep slips.
In the top left position you are in Low ratio with the CD locked. Useful for extreme offroad - or for slippery slips! Again, light should come up on dash.
It IS possible to range change from Low to High whilst moving, but you need to use both gear boxes. Best to get someone to show you how to do this.
Plan ahead & select ratios/difflock as appropriate rather than wait until you're stuck.
Difflock DOES NOT lock the front & rear axle diffs as already said & you can yourself REALLY stuck! The power takes the line of least resistance so if one wheel on each axle can spin that's what will happen.
After disengaging difflock, you may find the light doesn't go out. Not unusual as the CD can sometimes get wound up. Straighten the wheels & reverse for a few yards.
Note that the handbrake works on the rear propshaft only - the big drum to the rear of the transfer box. When jacking up to change a wheel chock a couple of wheels as the vehicle can roll, esp with a rear wheel jacked up.
If the door mech isn't working it could be the operating rods/cables inside the door or a broken spring - the latter is a known issue - & you'll need to remove the door trim. No end of Disco 1 being broken so a complete mech should be cheap enough off the bay - quick check shows some for under £20 incl p+p.
For the window check if power is reaching the motor. Cables between the pillars & the doors can break.Known issue with the window ECU. See this:
