How to Service an HVAC Pressure Switch on Chrysler 300M?

Start by pulling out the negative wire from the remote battery post, then separate the wire harness connector from the HVAC pressure switch and be careful as the slight pressure let out at this point doesn't require removal of refrigerant from the system. Turning the HVAC pressure switch which attaches to the valve at the discharge line, counterclockwise with a 14 mm open-end wrench will allow you to remove it. O Rings need to be swapped out whenever the HVAC pressure switch is changed, so use the one for your vehicle. First, do the steps in reverse for installing the HVAC pressure switch and tighten it to 6 N.m (50 in. lbs.). You must turn the passenger headlamp out of the way to reach the HVAC pressure switch.
