Dash lights and radio display flickers in a 2000 GMC Sierra 4.8L when brake is applied while driving. Checked tail lights, and rear blinkers, all work properly. Any ideas?
Is it the stock radio? if not, whoever installed the new radio might have ran the wire in the path of the brake pedal.Is it the stock radio? if not, whoever installed the new radio might have ran the wire in the path of the brake pedal.

not that this is going to really help your overall problem but I can tell you that smelling antifreeze in the cabin and if the foormats are wet in the front then it is probably your heater core that has sprung a leak. Think of your heater core as a mini radiator but inside the vehicle and they are usually tucked up inside the dash somewhere and is usually quite expensive to have repaired because of all the labor involved. I just replaced mine in my 2001 Mercury Grand Marquis and it took me about 10 hours to change out. And i am a mechanic.As for your electrical problems I would personally contact the dealership and as them about recalls or technical bulletins concerning your 2003 GMC Yukon xl denali. Good Luck.
Hi J, The ground connections are on each of the units. that is to say there is one power feed to the dome and another to the instrument panel. From there each door is separately grounded via each of the door switches. If one is rusted, contaminated or damaged and not operating correctly, it will cause the dome light and the door warning on the instrument panel to flicker. regards John
The regulator in the alternator is most likely the problem. The alternator could be charging.......just not correctly....... the flickering headlights are showing a varying voltage.......and with the charging light flickering too..........99% chance you need a complete rebuilt alternator.
You do need an alternator. Nissan has a campaign on Maxima alternator in certain years such as 96-98 I believe. Go to your friendly Nissan dealer abd have them punch your VIN number into the NNA net. they will know and that will tell them if your vehicle applies by the VIN. I have seen the alternator on fire. There was fire inside of the alternator. Have it checked or the car can catch on fire.
