Hi, I spent all sunday chasing this one.. Clutch not engaging. I tried jumping both hi and low side pressure switch harneses. NOTHING... in fact there is NO power to the harnesses.... i can feel and hear the relay click in the underhood fuse box when the dash AC botton is pressed.. AC worked FINE on Thurs Friday AC failed. .. we did use the cruise control on Thursday... all fuses check out... diode on the fuse box under the hood is fine.. Just no power to those switches.

thoughts?? HELP!!!
