jaysams80 Posted April 23, 2017 Posted April 23, 2017 C5 X7. Should the pump/motor be quiet running? Mine is not. How loud is a healthy pump? Quote
MikeLane Posted April 23, 2017 Posted April 23, 2017 Depends what you mean by "quiet". I've always heard mine (since 2005) when it operates. Quote
paul.h Posted April 23, 2017 Posted April 23, 2017 I can also hear the suspension pump on our 2007 C5 and could on our previous 2004 C5. Once moving though the sound is not noticed. Quote
jaysams80 Posted April 23, 2017 Author Posted April 23, 2017 Just trying to figure out if mine is strained. Had another fuse pop on me after stripping it all down.There is smoke which seems to come from the little black box fixed to the motor, where the power wires clip in. Quote
paul.h Posted April 23, 2017 Posted April 23, 2017 I think the box might be the bhi pump controller, maybe there is a bad connection inside or if you have a lds leak, liquid inside. Quote
jaysams80 Posted April 24, 2017 Author Posted April 24, 2017 Typically when I stripped it down, TWICE, I didn't think to look in there. A job for another day I think. Quote
