2005 Infiniti Q45. The navigation screen does not dim at night and when the driving lights come on. Sometimes screen will dim and brighten irregularly when the right rear window switch is used. Any suggestions as to what is at the root of the problem?

Probably a bad Body Control Module. Find out which switch (which door switch [LF door, LR door, RF door or RR door switch]) causes that to happen to help narrow down a wiring issue.

Hi

Are you loosing coolant ?

You need to pressure test the cooling system first, with a cooling system pump, (available at any good Car Spares Shop) to test for and eliminate any leaks, and go from there !

Also have the head gasket tested, with a Carbon Monoxide gas test, on the cooling system.


Good luck !

John

2015 Territory, for 6 months, if headlights turned on in day, dash lights usually dim, centre panel unreadable, sometimes will not dim except at night. When new, latter was norm, but now as above.


This is a different model in the States. If this has a display for the Navigation there are controls to set for brightness and auto adjustment for day and night. These controls are reached within the programming of the Navigation screen and independent of the dash lights switch.

You are probably zoned out of making adjustments when the screen is dark. So you will need to tinker with this when you can see the screen better.

On our vehicles the headlight dimmer switch only controls the dash lights. Could be you had this vehicle serviced. Sometimes when an OIL CHANGE is done the service technician wants to reset the oil interval and goofs up some other settings in the process. Think about when the problem started and if someone else had their hands on your vehicle.

This is caused by either a poor ground connection to the head lights or an overcharging condition taking place in the voltage regulator of the alternator, the spikes in output voltage causes the head lights to brighten up.

Have a look at the dashboard lights dimmer switch. That switch, losing contact momentarily while the lights are on, will cause the lights to flicker.

You will need to take it to an Autozone, they run the scans for free and can tell you what is wrong. They can also sell you the part that is causing the code to pop up.
