    AC pressure switch location?

    Think my switch may be bad, my scan tool has a false reading for the pressure. I checked with my gauges. Anyone know where this thing is located?
    Thanks

    I think it's this one. Should only have to remove the bumper to get to it.

    Actually you can change the sensor just by removing the headlight and the plastic cover over the sensor. Done it myself last month. You can just about fit a spanner there to get the sensor loose.
