Carquest Premium – HVAC Pressure Switch (Part No.ACA1315)

HVAC Pressure Switch

from

$20.99
The Carquest Premium line of vehicle electronics are designed for OE form, fit and function for both import and domestic vehicles. The A/C Pressure Switch monitors system pressures, aiding in proper and efficient control of the compressor, fans and system levels. An improperly functioning A/C Pressure Switch will provide erratic or inaccurate actuation and operation, severely affecting system performance and function. Without reliable and accurate actuation from a properly functioning A/C Pressure Switch, critical components and the system as a whole are left unregulated and unprotected which can lead to excessive wear and tear on critical components and costly system damage.

Product Features:
  • Designed and manufactured with high quality materials, industry leading electronic components and strict quality controls. Engineered to meet or exceed OE performance and to meet the uncompromising demands of service professionals.
  • Direct fit replacement matches proper OE fit, form, and function and ensures trouble free installation of your A/C Pressure Switch.
  • All units are tested using advanced end-of-line equipment that pressurize the A/C Pressure Switch, confirm proper calibration and functionality, and check for leaks to ensure each A/C Pressure Switch meets manufacturing specifications before packaging.
