Question about Chevrolet Tahoe

1 Answer

There is some sort of relay that is continuously clicking whenever the ignition in my 99 Tahoe is turned on. It is located below the glove compartment in what appears to be the fan blower module. Air conditioning runs okay but I do notice the a/c light blinking. ????

Where is the interior light relay on 2001 ford windstar


Your interior lights are controlled by the GEM - generic electronic module !
Battery Saver The battery saver relay is controlled by the generic electronic module (GEM) and is located in the fuse junction panel. The battery saver relay is designed to supply B+ voltage to the following:
  • dome and map lamp switches
  • visor lamps
  • glove box lamp switch
  • interior lamp switch
  • interior courtesy lamp relay
  • delayed accessory relay
The function of the battery saver relay is to prevent excessive battery drain by interior lighting circuits. The GEM supplies a ground signal to the battery saver relay anytime one of the wake-up inputs of the GEM is activated to operate the battery saver relay. A wake-up command is sent when:
  • any door becomes ajar or is opened or closed.
  • the ignition key is inserted or removed.
  • the ignition switch is turned from OFF to RUN.
  • the ignition switch is turned from OFF to ACC.
  • a wake-up request is received from the remote anti-theft personality (RAP) module (if equipped).
  • The GEM will maintain the ground input with ignition in RUN or for 40 minutes from the last input activation with ignition in the OFF position. After 40 minutes the ground signal is discontinued.
This de-engergizes the battery saver relay preventing B+ voltage supply to the controlled switches and circuits.

  • Short to power.
  • Damaged switch.

When I turn off the ignition on my 2001 Tahoe the amp continues to pull power. It does not turn off. In a couple of days it will drain the battery. To stop it I pulled the fuse. How do I properly fix it....


In order to answer this, it is necessary to know whether your Tahoe is equipped with the luxury sound system, the premium radio, or the sound system with rear seat audio.

Possible bad ignition switch? I would have it checked by a professional that can see what is actually happening.

I have a 2005 Tahoe with 43,000 miles and it will not start. It is not the battery. When you turn on the key all it will do is click and all light will come on.


Most likely the battery--even though you say no

If the battery is new ,then the solenoid on the starter
or the starter it's self

Where is the fuel pump relay located in 95 chevy blazer s-10?


The fuel pump relay in my blazer is located in the rear of the glove box which means you have to clean out all of the maps and other junk to get to it. There is a plastic cover that has to be removed to expose the relay which is the right side of the two present.
You can tell if it is operating when you turn the ignition key to "ON", the relay will click and you should hear a humming sound as the fuel pump energizes.

Fusebox location


Relay Center Cooling Fan Controller
  • Located behind the left side of the instrument panel.
Cooling Fan Controller Module
  • Located behind the right side of the instrument panel.
Cooling Fan Relay
  • Located in the air conditioning cooling fan control module.
Electronic Control Assembly
  • Located under the left side of the instrument panel.
Electronic Engine Control Power Relay
  • Located behind the glove box on the right side of the instrument panel.
Fuel Pump Relay
  • Located behind the glove box.
Horn Relay
  • Located in the fuse block.
Let me know if this helps. If not, let me know.

Circuit Protection The fuse panel is located below and to the left of the steering column.
Fuses are a one-time circuit protection. If a circuit is overloaded or shorts, the fuse will blow thus protecting the circuit. A fuse will continue to blow until the circuit is repaired.

Main fuse box located on driver's side to the left of the steering wheel, above the brake pedal.
