Re: 95 3.4 security light always on
When you say it is "always" on, do you mean "always" or just when the ignition is on and the engine is running ? Is the light on solid or flashing ?
A loose connection at the ignition switch, or a bad switch, can let the BCM know that the correct key is in the ignition, but will make the light blink during run. The only way to know is to hook up an ohm meter and check the vats resistance throughout the entire movement of the key. It should stay the same. If it changes as you move the key, you have found the problem.
