I recently replaced both airbags in my 2000 blazer and now when I try to blow my horn my running lights come on. Front amber lights and back lights and lights in my mirrors(turn signal). If I push my airbag in lights come on till I release. Please help. Thanks You

 

I do not know where the hazard warning switch is on a 2000, but if it is on the column, is it possible that there is something behind the horn/airbag that is physically pushing on the hazard switch inside the column when you push the horn? If it was me, before I pulled anything a part, I'd turn the hazards on and then off to insure the switch isn't in a "half-cocked" position.

 

I checked switch and it's fine. Luckily I didn't put everything back together. Just plugged in all my plugs. Will start checking wires asap
