Anyone know of a good Chevy forum? I have a 1998 Chevy Silverado and after getting the brake booster installed the cruise stopped working. First thing I did was check the fuse, it was good but the voltage reading with the key on was only about 3 volts. All the other fuses read >12.5 volts. The Truck is old so I would like to try and trouble shoot it before I accuse the mechanic of messing it up.
