What This Product Does
This electrical switch provides an operating input within the heating and air-conditioning controls. It is an individual control component rather than the complete dashboard control unit, a blower motor or a temperature-control knob.

Functions

• Provides manual switching within the cabin climate-control assembly.
• Replaces the corresponding tip switch on compatible M573-equipped vehicles.

Technical Details

• Brand: OE Match.
• Part reference: 94465392200.
• Component identification: tip switch.
• M573 denotes cars fitted with air conditioning.
• The supplied 964 application specifies left-hand-drive cars.

Symptoms of Fault

• The associated control does not respond when operated.
• Operation becomes intermittent or depends on pressure applied to the switch.
• Visible damage affects the switch or its electrical connections.

These symptoms do not establish that the switch itself has failed. Inspect the electrical supply, earth connections, terminals and related wiring before replacing components.

Why Replacement Matters
A confirmed switch defect can prevent the associated cabin control from responding consistently. Replacing the faulty component addresses that switching fault without assuming that the entire control assembly needs renewal. Match the existing reference and vehicle specification, and check surrounding connections for damage that could cause repeat problems.

FAQs

• What does M573 mean?
  It identifies vehicles equipped with air conditioning and is a requirement in the supplied application information.
• Does this fit right-hand-drive 964 models?
  The supplied 964 fitment specifies LHD cars; right-hand-drive compatibility is not confirmed.
• Should an intermittent fault automatically mean a new switch?
  No. Loose terminals, wiring faults or poor electrical connections can produce similar behaviour, so diagnosis should precede replacement.
