I have a 2002 suzuki xl7 and when you press the brake pedal it blows the fuse, cruise control and horn are on the same fuse, when you blow the horn the fuxe does not blow but as soon as you push the brake pedal the fuse blows. could it be the cruise control switch by the brake pedal. Please help thanks

Trace where horn is and place multi meter on dc and connect to horn connector then press horn and see if voltage appears if so its your horn if not its possible your s-wheel or stalk connection. Hope this helps

Sounds like they are guessing and dont want to, or cant diagnose it properly. First make sure fuse is good (fuse 6) , make sure brake pedal switch is adjusted correctly. (if it thinks you are pushing the brakes, it wont cruise) check fuse 47 (if horn blows, fuse 47 is good) make sure cable is connected at throttle body. check these first, the rest gets complicated.

I have a suzuki XL7 and the heater will not blow hot air, it will blow warm air if the setting is on defrost but not otherwise.

something is shorting to ground...look for any bare wiring...i had one time ..a brake light fuse kept blowing...after about 2 days found out it was the bulb it self (it was working too)...strange ???

Here is an idea, when do you blow the fuse key on, key on engine running, key on engine running hitting the break pedal? Try and get the key on without blowing fuse if possible, then one at a time try those circuit loads ie: horn, brake pedal and so on, if you isolate which load is pulling to many amps(blowing fuse) unplug that load itself, then restart testing, see if fuse stays ok. You can also substitue the fuse with a circuit breaker and unplug each load until click(of breaker) stops.

i would look at the brake pedal sitch for chffed wires or shorted to ground

replace nuetral safty switch for gear shifter and check window relays

The horn and rear brake lights are on the same fuse. Eventually the horns rust out like on my 1998 CRV. Once I replaced the horns, I could put in a new fuse without it blowing every time I sounded the horn. Problems still remain, namely: the cruise control does not engage and the remote start only starts the engine that runs for two seconds then dies. Still looking for an answer. It's a "Code Alarm" with Codestart dated 11/24/99.

check under the dash st the brake pedal,there is a brake light switch which is tied into the cruise control,you could try unplugging that and see if it fixes the problem(remember you will have no brake lights while it's unhooked) if the problem is gone replace the switch.

It sounds like the cruise control switch on the master cylinder (if youhave cruise control). It's a Ford recall.
