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-. |
