Hey guys, someone has had to have this issue before. Please help. I replaced the relay and the Air Pump tested O.K.

I think I know why the pump wont kick in and raise the Navigator. This Blue/Yellow wire is not getting any power and I cant figure out why. I am not sure what this Blue/Yellow wire is for . Can someone chime in and help me out.

 

That wire is used by the control module to supply the ground to the relay coil. See the attached PDF.

 

My suggestion go coil over. Eliminate all go these costly problems. Example: I replaced the compressor, one month later the front was loosing air, than I purchased new bags. Then still wouldnt work properly I had new issues. Finally I said the He.. with it and purchased new oil overs. Under $300.00 and there a dream. Should have done it long ago. You an sell your existing stuff and probably get back your $. I did!
