First of all I have a 99 SE-L without climate control. The heater/A.C. fan only works on 4. Is it the switch or the motor itself?

The other issue is when you close the sunroof it sags down, preventing the seal from being formed. If I am not careful the roof will leak if I don't manually raise the glass to create the seal.

Any help is appreciated.....

 

there no way of telling with that information you given youll have to test the parts/wiring (i dont know what a maxima with out climate control looks like so im not exactly sure how the dials/switches work)

as for the roof it sounds like there is a worn part in the tracking where the rail is suppose to stop and now is stop further then where it should

all this seems obvious

 

the reason for your climate control working only on 4 is that your BLOWER MOTOR RESISTOR IS BAD, it is located behind the glove box near the carpet it is either a black or brown credit card looking resistor. COst $30 from autozone here you go

Thanks for the help with the blower motor maxfever. I am going to give that a shot as soon as this weather lightens up a little.

As far as the roof goes does anyone have any idea of what part or parts would cause the sunroof not to close to the sealed position? The roof does close all of the way but it just sags towards the rear instead of sealing with the roof line. I can get it to seal by tilting the glass up.

 

I just had the same issue with my blower fan. Replaced the resistor last night for $36 at advance auto. 5 minutes of work and I have my variable speeds back. Thanks guys!

 

Is the sunroof motor weak? Or is it all manual? U may jus need to re-seal. HArd to visualize w/o pics
