Carquest Premium – AC Pressure Switch (Part No.ACC1605)

AC Pressure Switch

from

$92.99
The Premium CarQuest Vehicle Solutions line of vehicle electronics are designed for OE form, fit and function for both import and domestic vehicles.

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.
