2010 JETTA HORN BLOWS WONT START

if you have a problem with any code or blown fuse or brake issues remote start will not work [safety reasons ] check fuses and connections also brake light switch

It depends on how many amps the 2010 trail blazer horn uses & the size of the fuse for the horn in your saturn. The horn for the trail blazer should be labled on it somewhere as to how many amps it uses & you can find the horn fuse rating in your Saturn by looking in the owners manual. If U can't find or dont have the Saturn owners manual find the fuse block and the horn fuse location should be labled look for the fuse rating on this fuse, pull the fuse itself if U have to but remember to put it back. If you know the rating 4 the trail blazer horn and the Saturn horn before you try to switch them it will save U time and you wont fry the horn wires possibly in the Saturn. Good luck!!

Need to put key in drivers door and lock and unlock. This should stop the horn immediatly and car should start.

WHAT DO U MEAN WONT BEEP?DO U HEAR IT WHEN ARMING AND DISARMING?

try turning alarm off with key under hood or bonnet

switch ignition on, engine off. fully open window fully close window, lift and hold window close switch until window motor emits a clicking sound, repeat procedure for remaining windows,switch ignition off. sound like battery been replaced disconnected, if this procedure dont work let dealership check it out.could have blowed window switch fuse to that door.

Have you checked your Fuses sometimes if one blows it could cause the car not to start depending on the fuse.

try honking the horn normally with horn button <key must be on> if horn works it is in the programing for comfort and convieniance system if no honk it's just the horn or wiring to horn.

you may need to put a relay in it as the current from the horn may be back feeding up the immobiliser horn circuit and causing a short. Sounds like the immobiiliser has its own source of power seperate from the factory circuit When you press the horn the power goes to the horn and up the immobiliser horn circuit and it blows the fuse.

Same problem on 98 Jetta at about 9 yrs of age.  Wiring harness was an expensive job.  Dealer replaced all wires going to doors so that alarm isn't mistakenly triggered by opening doors.  Dealer offered to remove alarm for a few hundred dollars, but couldn't assure us that the key fob would still open the door locks.  Who wants to give up power locks? My hunch is that wire in driver's door breaks with flexing over 9 years.  Could consider replacing short stretches of wire in hinge of drivers door if you're handy with a soldering iron.
