I have a 2004 Suzuki Verona and after i got a jump my power windows, door locks, turn signals, hazards, and rear defrost have stopped working. I have checked all fuses and relays under the hood, in the fuse box, and the hidden ones on and behind the bcm. Any ideas on what it could be.

Look at the end of the dash and between the drivers side door for a second fuse panel. I think everything you mention works on one data bus. You can remove the button pad on the drivers door. Since it gets used all th3 time i# might have gone bad messing up the works.

Sounds like a fuse which located under the dash by the steering wheel.

its a 5 amp fuse located under the dash under steering colum it has i think 6 fuses in a single line... check which one is blown i believe is says IA or something

fuse check fuse
my guess you ment the key fob is dead, and electric locks are dead, i bet the key metal part works great .check fuses.

I have a 2006 with a similar problem. Apparently there is a good chance, with Suzukis, of blowing the main fuse at the battery. Also have read about another fuse block under the steering column, not identified in the manual, check those fuses. My problem developed when I jumped the battery and lost all the items you listed plus the radio. Should here from mechanic today if problem resolved

had the same problem in my 2004 verona.look under your dash below your steering wheel.you will see a small fuse box with fuses on the very bottom of it.look for the yellow 5amp fuse which will be blown.change that baby out with a spare fuse and pow!everything is good again and u didnhave to spend more than 2.00 for a fuse lol.ets get it donelet us check back with us afterwards

If everything else is working properly, I think you are on the right track with the fuse. On MOST cars the fuse box is under the dashboard but check your owners manual for the location. A diagram is usually on the inside of the cover or the sockets are marked.

it is located in the fuse box the one that is inside the vehicle.

This may sound silly but place the actual key in the drivers door and cycle locked and unlock this should reset the security system.

because you reversed the polarity you could have blown some fuses check them out and continue. joe
