QuestionThe rear windows will not open. They did this once before in the open position but now they won't do anything. The front are still working but I am sure it is just a matter of time. Do you have any idea what would cause this and is it something that can be fixed WITHOUT taking it to the dealer? Please say Yes.
AnswerHi T;
Our older Disco's (series I) have problems with sticking windows. Its normal for aging LR's. The power window (PW) control unit can begin to fail (contacts are worn); the window motor can corrode and start to fail; the assembly unit the moves the window up and down can corrode and even rust - so much so that the window to slip out of the resting flange and drop completely to the bottom of the door. Water and moisture are part of the reason. If you live in colder climes (like me) you get use this and know that during humid days you don't touch the rear windows.
If you are good with tools, you could take the door panel apart and clean up all the corrosion and rust you find. Install a new rubber liner for the windows (US$25) and lubricate EVERYTHING with some lithium grease (water repellant grease).
The rubber liner that sits along the edge of your door, acts like a squeegee to prevent the ingress of water into the above mentioned area. You can try some Armour-All or other cleaner lubricant to soften up this rubber. I found that it sometimes grips the window too tight and thus the window refuses to move down. The PW motors are strong but they do eventually fail with age.
So, yes you can do this yourself and, if possible, find the HAYNES REPAIR manual #3016 for our Disco. It has excellent instructions and photos to help you out. You could also buy the actual LR shop manual but it usually sells for $150 or more. Haynes is about $30.
Best of luck, T.
If you have any more Q's or want to tackle each window yourself, drop me another Q and I'll give you some pointers or at least point you in the right direction.
