Q: How do you remove the pressure sensor near the air conditioning compressor for Cadillac Escalade?
A: Working near the air conditioning compressor, unplug the electrical connector from the HVAC pressure switch. Remove the switch from the air conditioning line fitting. Be sure to hold the fitting using an open-end wrench to prevent deforming the pressure line. Install the new HVAC pressure switch, then tighten it securely. Reconnect the electrical connector.
