'97 900 SE-T - Low, pulsing sound -- not sure of source Posted by Frank [Email] (#2509) [Profile/Gallery] (more from Frank) on Fri, 21 Oct 2011 14:00:49 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Just noticed today a new sound coming from the engine bay near the firewall. Whether I have the engine going or just have the key turned to "on" while listening to the radio, the sound is there. It sounds like a low pitch pulsing sound.....like something out of a science fiction space movie.
I have no idea where it came from. No CEL light. Check brakes alert that comes on when you fire up the engine goes off as soon as I tap the brake pedal.
I mention this because I was thinking it might be the vacuum booster or something like this.
Not sure what comes on when the key is turned to "on."
Any ideas will be appreciated. Frank
