Product Details

Dorman 599-002 is an HVAC control module replacement for select Pontiac Montana and Oldsmobile Silhouette models. It uses a 2-connector, 16-pin configuration with a bolt-on mount and does not require programming, making it a practical solution when the original climate control module stops responding or operates inconsistently. This part cross-references 15-72704 and 10301047 for the same application.

Common Problems It Can Solve

  • Climate controls do not respond
  • Blower, temperature, or mode settings stop changing correctly
  • Manual HVAC panel functions intermittently
  • Rear window defogger control circuit issues tied to the module
  • Failed original HVAC control module

Installation Notes

Verify the vehicle has manual air conditioning controls and RPO code C49 before ordering. Confirm connector count, pin count, and mounting style match the original unit. No instruction manual is included, and no mounting hardware is listed. Because programming is not required, installation is typically a straightforward module swap once the dash trim and control assembly are accessed.

Quality Assurance

This Dorman replacement module is fully tested before release to support reliable operation after installation. It is intended as a direct replacement for the original HVAC control module on the listed Pontiac Montana and Oldsmobile Silhouette applications.
