Dorman Cruise Control Vacuum Servo 47077 - Fits Camaro, Firebird, Corvette, S10, Jimmy, Blazer, Astro

If your cruise control isn't holding speed or just doesn't work at all on your classic GM ride, the vacuum servo is a common culprit.

This Dorman unit (part #47077) is a direct replacement for a ton of models, including the Camaro, Firebird, Corvette, S10, Jimmy, Blazer, and Astro vans.

It's a brand-new part, so you're not getting some old, leaky junk from a junkyard.

This specific one is for the left-hand side placement.

It crosses with the OEM number 14056624 and AC Delco's 15-72234, so you know it's the right fit.

Installation is pretty straightforward—just reconnect the vacuum lines and the electrical connector.

Pop that hood, swap it out, and get your highway cruising comfort back.

No more messing with the throttle on long trips.
