The most common reason batteries drain on cars is a bad diode in the alternator. The alternator will still test out good as far as power output goes. Try this: disconnect the positive cable(largest) on back of the alternator and then touch it back to the post you removed it from;( remember it is hot so don't touch it to a ground) if it sparks as you touch it to the same post then it is probably the alternator causing the drain.

Are you sure you need the fuse for the cruise control. My cruise control wasn't working, neither were my brake lights. All 7 bulbs were burnt out. When the brake lights were replaced the cruise control worked.

It shouldnt. The cruise control senses by the switch on the pedal not by the lights.

the plug behind the battery might be unplugged or that same plug is disconnected from the fuse box

There are several dash lights on a Mitsubishi Triton. There is a light to indicate a hot engine, low battery current, high beam lights and when the cruise control is engaged.

The cruise system shares fuses with the engine and brake lights. If the car runs and the brake lights work, it is not a fuse.

I had this same problem with my 2003 Venture. The Cheverolet dealership told me that the cruise contol is directly linked to the brake lights. The simplest and cheapest place to start would be to check your brake lights...if they are not working, you will not have cruise control.

No cruise control or fender mounted brake lights on a 2002 Tahoe could mean a short in the wiring or the ground wire has failed. No cruise control is also a result of a bad oxygen sensor. Most GM made vehicles have two oxygen sensors.

The cruise control may not work is there is a problem with the brakes. Check to ensure that the cruise lights come on in the dash. Also, check all the vacuum lines to see if there is any issue.

One for brake lights, one for cruise control. If you hit the brakes when using cruise control, that second switch is what tells the control modules that the brake is being depressed.

The cruise control is fed by the engine computer through the brake light switch. It does not have a separate fuse.If the engine runs and the brake lights work, it is not a fuse.

The cruise system shares fuses with the engine and brake lights. If those work, it is not a fuse.

There's a switch labled aux lights above and to the left of the steering wheel, next to the cruise control switch.

It is important to know the meaning of flashing lights in a car. When the cruise control set light flashes, it either means the driver hasn't finish setting the control, or that there is an issue with the fuse or wiring.

There are two. The brake light switch and the cruise control cut off switch. You are probably talking about the cruise control cut off switch. When you depress the brake pedal, the brake lights come on and the cruise control stops. Hope this helps

Sounds like the brake light switch is broken or out of adjustment and yes it would cause the cruise control not to work.

Are your break lights working? Not sure, but some times mfr's disable cruise when brake light(s)is out. Otherwise try fuse.

Common issue...if the brake light swith is not working; the cruise control will not engage and your brake lights will not go on. replacing switch is easy and inexpensive...its located in the upper part of the brake pedal.

Some cars have 2 switches on the pedal. one for brake lights and one for the cruise cont. Did you replace the right one??

A combination switch is the unit behind the steering wheel that hold the controls for the lights, cruise control and window washer.

You probably have the problem with the faulty brake pedal switch - this was a recall item. Your cruise control may not work either. There is a switch that when you press the brake it triggers the rear lights and also tells the cruise control to turn off temporarily. This became faulty on mine over a period of months where the cruise would sometimes work, others not. then the rear brakes kept staying on. Should be fixed for free as it was a recall. **This happened to me today, with the dealership closed for the weekend I was worried the battery would die before I could get it fixed. I tried pulling back on the brake pedal as much as I could with my hand and it turned the lights off.**

Yes, but it depends on what your problem is. The switch normally has different circuits for the lights, the cruise control, and a computer feed.

The signal lights, the high/low beams, the cruise control, the wipers, the wiper delay function, the windshield washer and the 4-way flashers.

Start by removing the connections for the cruise control and brake lights, then remove the bolt that holds the switch to the brake pedal. Once the brake pedal is loose the switch is held on the brake pushrod by a bushing with nylon retaining washers. Carefully remove one washer and slide the bushing out, the switch can now be removed from the pushrod. Installation is the reverse; line up the hole on the switch with the hole on the pushrod, make sure the tabs for the cruise control and brake lights are facing properly. Reinstall the bushing and replace the other nylon washer, replace the bolt and tighten. Lastly connect the brake lights and cruise control.
