Inoperative System
If road test verifies an inoperative system, check and verify the following:1. Check Fuse No. 25 in the power distribution center.
2. Inspect vacuum hose and electrical connections for loose, corrosion or bent terminals at servo.
3. Check for correct position of the vacuum check valve in the hose from servo to vacuum source. The word VAC on the valve must point toward the vacuum source.
4. Ensure both ends of speedometer are securely attached.
