Bought a 95 maxima. Was passed threw a few people in my town then traded to someone in neighboring city and I bought it from him. I don't get how to do diagnostics. Screw keeps turning so no idea on what computer has to say cel only on now n then. Hood flew up on prev owner smashed window n sunroof and they took sunroof out n bolted in some sheet metal. Wiring is a nightmare but I'm good at it. But ran into a place I need some help. Anything the door switches do is non functional. Rolling down windows is running wires from a battery. I've gone over FSM an narrowed it down. Bcm, circuit breaker, Or big clip on bottom of junction box that fuse breakers are on. Need a hand with...
No dome light. Can't check bcm(if that would even stop them from working...idk...)
No clue how to reset breakers. They are round and black.

Can't get big clip to release. It looks like its in there funny. Not fully connected.

Too hot for no windows. If related blower motor not wprkin either. Nor door lights or power locks...unless I manually lock passenger door the rest lock cept driver. And rear passenger window just kinda falls. No press of buttons..

 

sounds like an interesting purchase...hope you didn't spend more than a grand on it


Anyhow, first and foremost check all fuses. IDC if you've done it already, do it again. Does the instrument cluster backlighting work?

Find a known good master window switch and put one in.

 

 

1) go to an auto parts store and have the codes read. If they tell you they can't, the car is not OBD II, you will have to educate them. The car definitely is OBD II and the connector for it is on the passenger side by the ECU. I'm not sure if you have to remove the plastic trim panel that hides the end of the ECU to see the OBD connector.

2) the sunroof and the power windows share the same circuit breaker, CB2. The power seats use CB1. Both circuit breakers are the automatic re-setting type.

3) the body control module (BCM) can prevent the windows from working. So can the master power window switch in the driver's door.

4) power door locks - See # 3 above.

5) rear passenger window - Either the widow regulator wire has broken or the big gear inside the motor has broken apart.

6) Heater blower motor - Not related to windows or other stuff. There are 2 fuses under the hood for the blower motor. Check them. If blown, best guess says the blower motor is bad. If the heater controls are the manual type and the fan does not run on the high speed setting, best guess says the blower motor is bad. If the auto controls, 80% blower motor and 20% fan control amplifier.

If you go to a junkyard for the BCM or power window switch, 95 & 96 are the same. 97 and up are different.

 

Sell your car and buy a different one

 

doesn't look like the few different owners didn't take care of this maxima..

hope ya didnt pay too much for it.

 

Why are you worried what he paid for it? You're not helping him at all.

 

i can say if he's got the patience and the time and a little knowledge you can probably narrow down all those issues. i have the door locks going crazy on me now, been going on for a few months, thought about doing a master switch replacement myself but not a big enough issue to ignore my squealing front brakes. gl

 

Part it out...

 

Wow, a lot of replies. I paid 700 for it. Its got 1 major issue a hand full of annoyances and a good body. Its a project/toy. I knew there were gonna be times like this.

I'll check over fuses again tomorrow after a trip to junk yard. (I blew a 7.5 and don't have replacements)

The backlight works on gauges.
The driver switch works. Picked it up n tested it at junk yard might b from a 97 tho...

Didn't realize it was obdII. I'll do that also tomorrow.
Since they share breaker, is circuit incomplete without sunroof? Picked up another breakee from yard today haven't changed it yet. Got a sunroof removed just need to pick it up from yard.
I'll check into blower tomorrow. Window switch I got from a 96 I believe.. I'll double check at yard torrow

I don't get discouraged easy. If it wasn't this car it was an 83 Mercedes that did a disappearing trans fluid trick. Been doin this with cars since I was 16. (29 now) I've never had a mechanic touch my cars for more than tires. I grew up working in a junk yard(11-18) and come from a family of mechanics(moms side) and electricians(dads side) and musicians(both) and that's what I do. Contracting, auto repair, and play guitar.

Thatnks for the help. And the discouragement it makes me want to make mine better than yours

Added...
Maybe someone recognises car. Might have been a member. I'm from northern il

 

After you change your breaks, I'm not a maxima pro, bad had similar issues before. Check the little door sensors. I've had one of those go bad and it would go nuts and even make the dome light strobe basicly

 

You got 2 out of 3 right with that statement.

 

Does it have half of a body kit on there? Looks like side skirts of some type and the rear bumper looks lower than stock.

 

The circuit breaker that powers the sunroof and windows is wired in parallel, meaning the wire branches and and goes to each one. The power does not go through one in order to get to the other. That would be wired in series.

The power wire for the sunroof goes to the motor, not the switches. Was everything removed - the glass, the motor, the switches - or was it just covered over? Doesn't really matter, as long as the wire from the circuit breaker isn't shorted to ground and keeping the circuit breaker tripped, you would have power to the door windows.

 

Yea it has a body kit but stock front bumper. They weren't careful n front got destroyed. New one is $100 for R33 type. Once I get elexrical fixed and sunroof put in all the body work done and primed I will order it. Yes its lowered also 3 inch drop all around. And they removed entire sunroof all that is at the back of myind.fuel pump went out and I replaced it. While I was doing that my buddy was checking wiring under dash. Fixed that clip a relay that wasn't connected all the way and ungrouped the signal and constant wires for radio so it wasn't on all the time. Then checked every fuse by pulling em out one by one. Since we did all that. It won't start. I suspected fuel pump relay and jumped black n white wire to black n yellow n pump ran. But still won't start just cranks...adding a pic.. Is this the bcm? Someone wrote antitheft brain on it. I do not have a security light. And I have a black cable under steering wheel has a little chip thing that says guardian...

 

Pic

 

that looks like a bm1 color max like mine. hood pins, body kit and looks lowered to me from that pic. looks like it was beat on a bit, maybe you could hook up a guitar connection and play guitar from your max!! that would be cool.

 

I have only been in the community for a few months, so if this is wrong, please correct me.
The anti-theft is a starter interrupt, not fuel. The BCM should be under the middle armrest. Take the 4 screws out and left the whole center piece out.

 

I'm sure most of your door and window issue are related to a defective drivers door control panel which wear out faster than any other cause it's used more than the others! Buy yourself a V.O.M. and learn ow to use it and find you problems....Fuses blow for a reason....

 

I thought interrupt was ground to injectors? (Pulse) even when I hard wired fuel pump I had no pulse.
Wonder why I'm having fuel problems. I've checked n double checked everything. I thought box under armrest was airbag control?
FSM says it's under radio in front of and over CPU.

Not sure about color honestly it looks like its got a lot of spraypaint on it..but what's not is sparkly dark blue or sparkly white lol hood pins because latch broke. Looks cool too. Lowered 3 inches according to guy I bought it from not sure what body kit. Its kinda bland and damaged all over the place.

I know how to use one. I have one but its analog. And I'm not getting power to the harness white/red no 13....or 9 one of the two. So even if switch was good it won't work its from a 97,so from what I hear it won't work. Actually... If I manually lock passenger door they all lock cept driver... So power wire must be bad coming in to door.ty cmax

 

Sounds like an aftermarket alarm was installed....and may have been integrated to the ignition/fuel. So anything the FSM says may be out the window

 

It was just a chip you can remove it was a starter kill. Cel not lighting up at all. Nor is srcurity light. No keyfob.No spark no fuel(injector pulse or pump) have air flow going into intake. Pump runs if I jump relay. Pcm? Cel light? Crank sensor?

 

The stock Nissan security system was just a starter kill. The 1999 model added a chipped ignition key that would turn off the fuel injectors.

The BCM is on the transmission hump in front of the shifter by 6 or so inches. If you have auto trans, the BCM sits on top of the TCM, otherwise it is by itself.

The fuel pump should run for a second or two when you first turn the ignition switch on to allow you to start the car, but after that the ECU will turn the pump off if the ECU does not detect pulses coming from the crankshaft sensor that senses the flywheel teeth, CKPS(POS).

 

I noticed check engine light wasn't coming on at any point..followed power from batt...when I was pulling fuses checking one by one I put the fuse in a blank spot...put it where it went...fired right up...

 

So I'm back to working on windows. 97 switch won't work? It plugs in.. N I'm not getting power to driver door

 

STOP


if you have a 95 or 96, the master from a 97 on up will NOT WORK.

 

^^^^ he's absolutely right.

 

got the windows working, the 97 one didnt work, obviously, so i investigated why original didnt work, all the little push pins were gone so i took the ones out of 97 and put em in, soon as i did passenger and one of the back ones worked but not the other 2, i tried later and blew a fuse tryin driver window, followed the wires from door into car, that clip had gotten wet and corroded to nothing, rewired all windows work fine. workin on getting security system working, then onto the body work....yay... speaking of body...i put the sunroof out of a 97 in it, it was bigger, had to cut roof...its a mess lmao, ill be steeling roof out of the junkyard and weld it onto it, or rivet and body work, havent decided yet
