1977-1982 Corvette Air Conditioning Control Vacuum Valve

  Having trouble getting your Corvette's air conditioning vents to open? Well, it’s usually one of two things. The plastic vacuum lines which run through the firewall are broken (usually at the firewall connector) or your heater and air conditioning control panel vacuum switch has failed. These little vacuum switches act as a “switching station” which redirect engine vacuum to actuate your vent doors. Over time, the wear from use simply causes the diagram to fail within the switch. Replacement used switches are affordable; but are a ticking time bomb till your next failure. Ecklers Corvette is proud to offer this new, high-quality replacement heater and air conditioning control vacuum switch. This switch is ready for many more years of reliable service over a used switch. Not only is a vacuum leak bad for your heater and air control system, but can lead to rough idle and other problems down the road. Ecklers Corvette wants your baby to perform its best.
