Grand Cherokee 2WD V8-4.7L VIN N (2000)
The IC within the combination flasher contains the logic that controls the flasher operation and the flash rate. Typical flash rate is about ninety flashes
per minute. When a bulb is burnt out, or when a circuit for a lamp is open, the turn signal flash rate will increase to a minimum of 180 flashes per
minute. However an open lamp circuit or burnt out bulb does not change the hazard warning flash rate.
Turn signal inputs that actuate the combination flasher are low current grounds, each drawing a maximum of 300 milliamperes. The turn signal inputs
are provided to the flasher through the junction block by the turn signal (left multi-function) switch on the steering column. The hazard warning signal
input is a low current ground drawing a maximum of 600 milliamperes. The hazard warning input can be provided through the junction block by the
hazard warning (left multi-function) switch on the steering column, or by the BCM on the back of the junction block.
