Where is the 2 nd fuse box on chev tahoe for cruise control

Question edited for clarity, full year make model, spelling 'Suburban' from Surburban.
Question moved to sub category.

No there isn't one. Cruise control is a joint effort from BCM and ECM. Check the Body Control Module fuses.

Most common failure (other than fuse) is the switch at the brake pedal which kicks it out of cruise. Switch must be in correct position and adjusted such that it is depressed fully when brake pedal is up.

The power for the cruise control comes through fuse #14 in the fuse box. From there it goes to the Cruise Control Switch. However, the Cruise Control Module is above the Fuse/Relay box, behind the dash board. Good-Day!

Hi there,

As you have not stated the Model of Chev, nor the Year of Manufacture, I will give you some general possibilities:

* Blown fuse
* Short or open in Cruise Control circuit
* Faulty brake switch
* Leaking vaccuum circuit
* Faulty cruise control switch
* Faulty stepper motor
* Faulty transducer
* Faulty speed sensor
* Faulty cruise control module

As with all electrical circuits, you should first check the FUSE.

However, from experience, the most common cause of inoperative Cruise control are:

Brake pedal switch: check that tail lights illuminate when depressing the brake pedal. If not, then replace the brake pedal switch (located up on the brake pedal assembly).

Brake pressure switch: depending on which model Chev you have, there is an electrical switch (look for wires) screwed into the brake cylinder (attached to the brake booster). This switch is a cruise system backup from the pedal switch and measures brake fluid pressure, to disengage the cruise control. When this switch fails, the Cruise Control will not engage. If you have a multimetre, you can test the resistance on the switch terminals (ask Chev for the correct resistance spec) - if not to specification, then replace the switch.

Cruise control release valve: this is the alternative to the brake pressure switch and is also mounted on the brake pedal, above the brake switch. This switch is designed to disengage the cruise control, just like the pressure switch. If you have a multimetre, you can test the spec of this switch (ask Chev for the correct test procedure & specs) - if not to specification, then replace the switch.


NOTE: depending on the year of your vehicle, your local Chev Dealership will be able extract the Cruise Control fault codes, stored in the Cruise Control Computer. This is always the fastest (and cheapest) way to identify the suspected component and will eliminate unnecessary "trial and error" labor costs. This test cannot be done by your typical garage and must be entrusted to your Chev approved service agent only, who will have the correct Scan Tool.

I take it that it's not working? 1 thing to keep in mind...if there are any check engine codes stored in the computer, te cruise control will be disabled. When this code is cleared out, the cruise control will work again.

There is a resistor panel that controls the fan speeds behind the glove box on the dash. You remove the glove box and you will see the airbox. Sitting down in the left top, with 2 screws holding it in, will be the resistor panel. It consists of 4 springs and a resistor. All out of veiw, inside the airbox. Remove the 2 screws and unplug the plug. Pull out the old resistor and replace with the new one. It only cost around $15-20 bucks at the local auto part store. This will get your fan blowing. If your fan is blowing but the air is not cold, I would suggest to check and see if the compressor clutch is working properly. If not, try giving it a light tap while running. If it is working, you may want to recharge your freon.

3rd brake light has it's own fuse.cruise is on same circuit

check for a small vac line loose-or leak at the cruise mechanism under hood...driver's side of firewall , check other vac lines also....

The BRAIN BOX which is known by most car owners controls the throttle boy accellerations control when engaging the cruise control on. If your fuses are good I recomend have the servo (brain box) checked

Check the fuse panel, it should be marked on their.
