Usually on low/dead battery coding of the 07 or 5F module (MMI Head Unit) is lost. When this happens camera stops working and some other features disappear from MMI screen.

Have a 1996 nissan terrano v6 petrol. The battery went flat and I recharged it. When I put the recharged battery back in the car sounds an alarm and wont start (immobiliser?). The alarm stays on for a...

When the alarm sounds, turn the key to the RUN (NOT START) position, then OFF - do this 10 times rapidly.
Many alarms will turn off and allow the car to start with this method.

My 1998 Silverado truck has no reverse. I took it to Mech. shop for brakes and service and now they say no reverse?

reverse takes more pressure to operate than other gears start with rechecking the fluid level if thats ok take it back to the shop they must not have installed the filter all the way

Overdrive light turns on and off

If it works ok then leave well alone ,this is not the first time i have come across this on a auto box but then not many autos around this area but i do know that if it works then dont play as the only one that i say that had been repaired cost a new computer ,well it did get sent to the frd dealer by a customer who bought the car from a second hand car dealer as it was a auto but they wouldnt pay for it as the car wasnt brought back to the car dealer for repair but taken straight to a ford main garage and we all know how they like to invent imaginary problems with main dealer prices ,most likely cause is the computer but it could be fixed by rewiring the switch straight to light for a hours work and a length of wire ,but the new computer job ?? and the car dealer paid up for good customer relations even though it was in the sales contract that the car had to be brought back and i would have rewired it .

1995 Audi 90 runs hot, blows sometimes hot and sometimes cold air

check anti-freeze level if you have a slow leak and level is low the heater core wont have fluid enough to supply the heat as fan blows through it and would also explain running hot if thats good have thermostat checked and changed for a lesser temp. shouldnt cost more than 25 parts and 1 hr shop time

Engine check light is on always now when engine is running,how ever car runs has a 170,000 miles on engine.

Any time you have a check light or any other lights. You have a possible system failure,and need to have it checked for a possible code,then diagnosed and repaired.

If you have inspection in your state,it will fail

Not to be hurtfull,but,these sort of lights have been on most all vehicles for 30 years.
There is no reason, anyone owning a vehicle, shouldn't have an owners manual,and be aware of the vehicles operation,as far as check lights.

This was brought about 30 years ago,in the US at least,as part of a program, to reduce exhaust emissions.

All of a sudden the 2000 jimmy seems to be revving higher and not shifting inot gear and the engine is getting hot, where rad fluid overflow is leaking when truck is shut off. I had the transmission...

Really they might be right after having a look but did anyone else from them drive the car?

The transmission might have gone bad but only manifest when engine runs hot.

Why not have a diagnosis scan on the car.

You might have a look at

Good luck.

Just brought used 94 cadillac deville ac works great but no heat

This is the the Cadillac Climate Control operates. When you press AUTO, the system will automatically maitain DESIRED temp . The A/C compressor will operate ALL THE TIME on AUTO. Don't want the a/c compressor to operate, PRESS " ECON". Air delivery will NOT be DE-HUMIFIED, nor will it cool, only warm,. Hope this helps.

Back up camera

I agree with Mike. The same thing happened to my 2007 Murano after I needed to get a battery jump -- my screen went black, no back-up camera, couldn't turn on radio or HVAC.

Brought it into my dealership who changed the battery, then they wanted to run a diagnostic (around $105/hr). I asked about the fuses, and thankfully, as it turns out, it was the "back-up battery fuse." Just paid for the battery and labor for that, and the fuse.

Charging Light On After Replacing Alternator/Battery1999Windstar

Hi, I can't tell you exactly what is wrong because there is too much involved at this point, what with 2 shops working with it, but I can give you some advise on what else to check. On the alternators and the wiring that supports them a small volt charge is taken off one of the slip rings, where the brushes ride, for the purpose of turning out the light. As I remember, this is a yellow wire that runs back to the dash.

To the alternator, it would be one of the wires that plug into the side of the alternator case.
