i had my moonroof open, when i went to close it, it got stuck halfway, so i had to help it along and push it so it closed all the way. so i decided not to use it anymore. one day i forgot it was broken and i tilted it up , however only one side will tilt, (driver side) the other side seems to be stuck. Now the passenger side is slightly lower, which leaves a bit of a gap so when it rains or i wash my car, water leaks in from the roof. any ideas??? HELP!!!!

Congradulations, your lack of sunroof mainteance [lubrication and rail cleaning] has allowed one of the two steel cables to have slipped its retainer or broken entirely. Only removal and inspection will tell you extactly the extent of damage and potential for repair difficulty.An expert can repair [8 hours with oem kit] or replace entire assembly from a junkyard unit in half the time.

We usually sell new oem replacement assemblies because used could develop same problem soon.

Rude and unnecessary-especially from a senior member and moderator.

If you can get the sunroof back to its original placement then pull the fuse while you decide whether or not you want to get into this HUGE job. There is a lot of finesse in getting it to work properly after taking it apart.

Actually, Q45tech is merely pointing out that without maintenance, systems fail.

As you pointed out, they can involve a lot of effort and cost to repair or refurbish.

As no one so far has commented, the information in the FSM will help illustrate this procedure.

Why is it rude to point out the truth. I didn't cause it!God did not cause it.Nissan didn't cause it.THE OWNER CAUSED IT!Owners must take responsibility for their own short comings and lack of automotive education. They chose to own a 15 year old vehicle they must be prepared for the results.Pain and Punishment.

It was rude, and your response makes you sound like a know it all and a jerk. Perhaps the guy recently bought the car. Did his lack of maintenance cause it to fail? Perhaps the sunroof has been regularly maintained and failed anyway? Perhaps if you merely told him what you thought was wrong without all the finger pointing and hubris this place (and you) might not have such a lousy reputation.

You guys are relentless. "Congradulations" (sp intentional)

I use the anything is better than nothing approach and use white lithium grease. If you use the can with the stick you can reach a bit further back in the roof along the rails.

Clean the rails first, then lubricate lightly with white lithium grease.

PB Blaster works good as a penetrant to loosen up the dirt but it's thin and will be gone in a week or two. Once it's all cleaned up with a penetrant then a coating of lithium grease will stay around for a long while.

PLEASE have someone [maybe 2-3 different shops] familiar with Nissan's design take a look at it and give you an estimate or two.The assembly comes out the top after you have removed the metal roof cover. Removing the entire roof headliner and sides is a serious job best avoided.

We got some people that were dropped on thier heads as babies. Ladies calm down now.

Anyways my roof makes a creek.Maybe need some grease?

I'm sure if you do tend to fix it and focus on doing it right,not rushing taking your time,it'll come out good as new.When I say take your time I mean if your stuck somewhere go get something to refresh and inspect.Then try again.Simple.Don't rush or it'll come out bad, unless you know it all of course.

the links are cast pot-metal (aluminum?) and are not strong or flexible--be careful. THe drive cables are very robust coiled springs with packed fiber (lube and kink prevention) driven by a toothed wheel (gear) on the motor assembly--foolproof--if the slides are kept free of grit. I suggest complete cleaning and then rubbing all the sliding surfaces with a DRIPLESS candle. The dripless candle is made of stearic acid which is an EXCELLENT luricant for aluminum sliding surfaces. Dry film, won't attract dirt, etc.

I see you that your in So Cal. There are several good sun roof repair companies in the LA area, not necessarily near Costa Mesa that I know of but start off buy looking for a sun roof company. At this point getting it closed and than pulling the plug is the best option for you as the cost of a full fix is lilkely to be as much as you paid for the car.

I had an old Maxima with the same issue and I eventually just gave up on it, but got it closed and pulled the fuse. There is a place on La Cienga Blvd called California Sun Roof if you want to get it working like new..also there is a great Nissan mechanic called Z Expert in Venice who would be able to probably get the roof closed of pull the fuse cheap. Call 310 396 7200 and ask for Richard, tell him Jeff Leeds sent you. It is not around the corner, but you can walk down to the beach while he works on fixing it and he's very honest and good.

Thanks for the excellent tip about the candle-I've always thought that grease replicates the problem and have tried graphite powder but am excited to try this method.

I am not sure if you call it a moon roof or a sun roof... either way.. Just bought this car! A 1993 Q45.. price was right.. paid $1000. Maplight console with switches, missing. i managed to get the roof closed by using a manual crank. Then.. I thought i'd open it! When I went to close it I heard something pop, like a spring that sprung.. Now it is stuck open! Crank will go backwards, but not forwards! If I know how something works, I think I can take it apart, and fix it! But this.. I have no clue!! Somebody help me?

Can you have someone pull on the sun roof while you use the tool to close it?

At this point, everything is in stuck position. I can try having someone pull on the roof.. is there something that should be oiled? A little PB Blaster can go a long way, if I know what to oil..

Roof repair require a lot of expenditure than that it is better to go for roof improvement work which would require less expenditure.So,many people go for these and they are many online services that provides roofing services to the maximum least cost.It is better to chose the services that are done online..
