My navman has stopped talking to me it makes noise when i go over speed limit but she wont tell me directions how do i get it to talk

Can you talk a little slower, not sure I understood your post? If you have a tire problem, you may need to safely raise and support the vehicle, Check the tire--check steering and suspension. Also, check halfshaft, where applicable.
There are safety issues working around or under a vehicle in the air. Safety is your responsibility.
I don't know your year--make--model?

If you're talking 4000 rpm, in neutral you'll cause engine damage! 2000 RPM is the max safe limit. Power loss is usually due to a restricted fuel filter. Does it smoke when running? (air filter), Try some Isopropyl alcohol deicer or fuel injector cleaner to ensure there's no water in the system. you haven't given enough info to diagnose the problem, i.e. drivability, history, and symtoms.

What type of vehicle are you talking about? And does the opposite side operate correctly? What are you referring to when you say stalk returns to off position? If you are talking about the directionals or turn signals of this vehicle as to when you make either a left or right turn and it not shutting off when the steering wheel is turned back after the turn has been made then you're dealing with a canceling function within the directional or multi-function switch.Not sure if this is what you're talking about when you are reffering to indicator flashing.

rebuild time may ckeck the modulator on the side of the trans if you are talking about a gm 350

Thank you for asking me directly to help you with your problem. However, it is quite impossible to provide any information about your security or immobilizer system. You didn't mention what kind of car you are talking about (year, make, model, engine size) or if you are talking about a factory installed immobilizer or an aftermarket immobilizer. This is really need-to know information if you would like a helpful answer to your question.

do you mean high engine speed or fan speed.
if fan speed is slow then motor in the fan is getting bad.
if your talking about running engine, then could be nothing because the sensor tell it not to..like running down the road it cools the car down and engine temp drops slightly enough to cut sensor off.

Are you sure hes not talking about a wheel bearing for your front wheels. A throwout bearing will sometimes make nosie like a rattleing if it is not engaged. When engaged it will sound like a roaring nosie. I would check in to were this nosie is coming from first.

There is a wheel bearing inside the hub as well. They will sell those bearings I've bought them before. Chances are you need to talk to a better parts guy. You can tell if it's a wheel bearing by taking the vehicle up to a speed where the noise is clearly audible. Then swerve the vehicle back and forth in your lane. If the sound changes or goes away when you swerve, it's a wheel bearing. Obviously we're not trying to crash the vehicle here, so don't get over aggressive with the swerving.

you think small words (short) finds and fixes complex machines
that be impossible but in your case, the first post ever
where the NV247 J transfer case actually state
New Venture make

first off no statement of where YOUR TIRES are sitting on.
dirt, show, ice, pavement , on road, off road. what????
we cant guess that. only that it makes noise. and all do driving wrong,
4 All time-N-4 low.
are you using 4-low, then stop doing that ON ROAD.

the box runs a very special fluid for the
"Gerator pump, which uses special transfer case lube
"
do not play with this fluid or use GL4 or GL5 or mix in other wrong fluids, or omg adding additives of any kind like dang LOOCUSS bs.

your video is dead.

tell when it make noise
in ALL Time mode? only
all speeds
all gears in main trans
accelerating only
decel?
turns? only
like that, or why not get a real 4wd shop to find it.
as we are blind here and cant hear, or drive it .

Could be your Speed sensor that would make the abs light come on because its not sensing the speed you are traveling. I have no Idea why when your gas gauge is on empty it won't shift. May be its the speed sensor and it was just happened to do it right when you where on empty. Does the speedometer work right or is it erratic? Let me Know this sound like and interesting problem I would like to work on and trouble shoot. Your ECM may be going too. There is so much going on Its hard to tell. But I would make sure the speed sensor is working properly first, Ok Talk at you soon. Thanks Bear001... Oh Yeah make sure all fluids are up and in good condition
