Volkswagen Golf Service & Repair Manual: Air conditioning system pressure switch -F129

This pressure switch has 3 functions:
1. Switches radiator fan to next higher speed when pressure increases in refrigerant circuit (approx. 16 bar).
2. Switches the air conditioning system off in the event of excess pressure (approx. 32 bar) (e.g. because of lack of engine cooling).
3. Switches the air conditioning system off in the event of insufficient pressure (approx. 2 bar) (e.g. because of loss of refrigerant).
  Note
The air conditioning system pressure switch -F129- replaces the high-pressure switch for air conditioning system -F23-, the low-pressure switch for air conditioning system -F73- and the high-pressure switch for magnetic clutch -F118-.
