For location and replacement of the BMR. Remove the shroud below the glove box, 2 screws and a snap-pop fitting. Be careful of the courtesy light. Remove the blower moter and disconnect the power harness - - you'll need this extra room to work with. 2 more screws, same size, 7/32, 6.5, 7or 8mm on some, that holds the blower motor resistor in place. This replacement part is less than 40 bones at most parts store. Unplug, replace, re-install, test and you're on your way with about 2 hours of slow paced effort in your own driveway. Typical cost at a garage/dealer - up to $400.

If your horn isn't working and it isn't the horn itself the next thing to check is the horn wire in the steering wheel under the air bag. The little clip breaks off in time and the horn wire pops out. To repair you can remove the wheel and replace the part but I usually grind in a new notch in the old plastic and re attach the wire and it will work again.
Test the horn itself first. Just remove the connection to the horn and attach 2 wires to a live battery and tough the 2 sides of the contacts on the horn. If it blows the horn is good. If not replace the horn before you go any further.
