A couple weeks ago the horn on my 03 tacoma started blowing.as i walked to the truck it stopped,then started,then stopped ,then started.then stopped. I opened hood and took battery cable off.before it got dark i put cable back on and raised windows but i forgot to take the cable back off.so soon as i went inside it started blowing again.by time i got dressed and outside several minutes had passed and it stopped before i got hood up, but i took cable off battery anyway.next time i wanted to drive the truck i put cable back on and took off driving,no horn!!!press horn button and no horn. I was walking into business front door up town and horn blew 3 times and has never worked again.today i took one of the horns off and hooked a test wire to it,grounded the horn and touched the test wire to battery, it only clicks.this truck has no alarm bytheway. Relay clicks which i read is located in the body ecu.i guess both horns are burnt out.AIR BAG LITE GOES OUT WHEN TRUCK IS STARTED SO I WILL ASSUME THAT IS OK.
Any info on this problem would be great.i would hate to replace the horns and this happen again!!! firstname.lastname@example.org
