I have a 97 volvo 850. The horn sounds constantly when the key is turned in the ignition. I do not have a keyless entry device, just the keys. I do not know how to disable the alarm. I have tried on the advice of an alarm website to put the key in the drivers side door, turn the key to the left then to the right, that should disable the alarm and reset it, but it did not. Next advice was to splice into the wire with and put a solid chassis ground. That did not work. I have located the black/yellow wire under the steeering wheel panel, that is the one I spliced. Please help. I can not drive the car until I can get the alarm to stop sounding.
thank you,
