Question about 2004 Chevrolet TrailBlazer
My trailblazer has a secondary air inj. code some say possibly a fuse where will the fuse be anyway and what is the steps of diagnosing this problem
The secondary air injection comes from an electric air pump (replaces the old eng. driven smog pump), it seldom runs, but when the car is 1st started you should hear if for about one minute, kinda sounds like a muffled hair dryer. The most common issue is the hoses get knocked off, 2nd is the electric motor failing.
