Having to pass inspection, my horn had to be working. On most 2nd gen, it likes to die and work 2% of the time. If you're one of them, there might be a simple fix.



1st - Check if your connection are good in the engine bay, in front of the radiator, under the black plastic cover. There's 2 horns.



2nd - The relay is located in the black C.P.U. box, on the driver's side interior wall, near the clutch pedal. It has 1 10mm nut holding it into place. If you push the horn buttons on the steering wheel and here a "CLICK" and no horn, try these instructions...



You'll need

soldering iron (20-45w is fine)

some solder

solder pump



remove the 3 connectors on the CPU box, 1 on top, 2 on bottom and remove the CPU.



there's 3 modules in it, horn, hazard and turn light. we need to popup the horn module which is the top one with the huge connector. just use a knife or flat head screw driver.



from here, remove the old solder on all the connectors pins so that you can remove it after. there is about 15-20 point to de-solder. when all solder is removed, take the white connector off and clean the pins with sandpaper. resolder it with new solder, put everything back and enjoy your horny rex.

 

One more thing to check before you do this is the fuse box. My horn didn't work and I checked my fuses and noticed that one was out. I put a new one in placement of the bad and viola the horn worked!
