Nissan Maxima 2001 GLE Sun Roof by haroldsjs

Last week I foolishly left my sun roof open a bit and forget to close it before I went to sleep. During the night, we had very hard rain and I had a lot of water in the area of the sun roof motor and switch, that is located in the roof just above the rear view mirror.
 
The sun roof stopped functioning and I had to loosen the motor to get the water out. I let the area dry out for a few days. The sunroof does not function as it did before the rain damage. It now opens and closes in about 2-3 inch in 2-3 inch increments. When in the fully closed position and the switch that bring the sun roof forward (closed) and backward (Open) is held to the closed position, the roof tilts up from the rear. That never happened before. That function was controlled by the other sun roof switch that only raised and lowered it. The switch that only raised and lowered the sun roof now does what the open and close switch does. It seems that the individual functions of the two switches now do the same thing. The up and down function of the sun roof only raises the roof about two inches. Prior to the rain damage, it raised the roof enough to accommodate the whole hand. It no longer does this.
 
Is the switch damaged from the water? Is their some other damage to the mechanical part of the sun roof? I am hopeful that it is only the switch assembly and not the other parts of the roof. Can anyone please advise me on this?

My daughter's 2000 GLE maxima has same issue, sunroof will open 2 to 3 inches on each press of the button. Not aware of any water entering the unit.
Dealer said the entire motor and cable needs to be replaced at cost of $900.00. Sounds like a lot of BS to me.
I can get motor assembly for 200 dollars. The motor and operation sounds fine to me. It just stops each 2 to 3 inches and another press keeps it moving, but a pain. Let me know if you find out anymore.

I agree that the dealers reply is BS. My mechanic said it could just be in the switch assembly. In my case, water entered into the switch assembly as well as the motor. I plan to take the switch out and disassemble it and clean all of the contacts, to see if this is the problem. If it is not, I plan to see if I can procure a switch assembly at an auto salvage yard and install it and see if that cures the problem.
 
I can not imagine that water would cause the motor to open and close the sunrrof in predictable increments every time I try it. If the motor became damaged I think the open/close function would be sporadic and not the same each time. It leads me to believe the damage and malfuntion is in the switching assembly.

The switch does not come apart. Both switches are on same mount bracket (2 screws) and are sealed. You can test the switch with ohm meter where wiring harness attaches.
The entire dome light and switch "pop" off by pulling down on the right hand edge of the switch/light plastic housing (pull on down on passenger side edge). Then disconnect the dome light and sun roof electric plugs and you will then have the switch/light assembly in your hand to do with as you wish. I was only uncertain about one position on the switch as I don't have wiring diagram. Given the switches are sealed (enclosed) hard to see how they would get wet. I am not ure they are waterproof however.

I have taken the switch down already. Each individual switch is far from water proof. Each switch has two-three small screws that hold the printed curcuit board in place. Each of these printed curcuit boards is also how the various wires enter the switch. I am thinks that a cleaning of the switch, with isopropyl alchol will drive out any remaining moisture and clean and resulting oxidation from the contact interface surfaces. I will write after I have done this.

Before you 2 take your cars apart you should do some more research. I was told by a Nissan dealer (Bommarito Nissan in metro Saint Louis) that this behavior indicates that a computer needs to be reset. I was told to hold down both buttons for 30 seconds and it would reset. This did not work for me yet, so I am in search of the magic to get the computer to reset. I have seen references to this in other forums. I will post back if I find it.

Harold, I had an issue several years back in my
2002 Nissan Maxima(totalled in a wreck last year back in July -RIP) where I couldn't get the sunroof to open at all. I wish I could remember exactly what I did, but I believe this
had something to do with when I had just had a new battery installed in the car, and at the time I thought there was something wrong with the sunroof(Actually, I was sort of cursing because my warranty had just run out!) But I'm
thinking I must have checked in the manual under the sunroof operation on how to get it working again. I just don't remember exactly what it was that I had to do. Does your manual for your Maxima have any info about the sunroof?

The same thing happened to me without provacation on my 2001 Maxima SE. All I did was disconnect the battery for a short time and it worked fine after that and has ever since.

The reset procedure for the sunroof on my 02 Maxima is to tilt the sunroof open then tilt it closed again. Once closed hold the tilt close button for a few seconds. This resets the slide control. If your sunroof is stuck in the open position you can use the tilt open/close to wiggle it back to closed.

That is total BS. One if the motor went you wouldn't be able to move the roof at all.
 
Secondly as it was stated before all you have to do is reset the moon roof. The way you Re- program the roof is by hitting the roof button so it opens it up all the way. Than close the roof in the same manor. By doing it a couple of time it will re program the roof. It takes about 5 minutes. That amount of work is definatley not worth $900.
