shot in the dark..
on my 99 xj, there is a small unit with two vac lines going into it. the location is on left side of engine bay, pretty much on firewall. it is a small unit, only a couple of inches in diam. it is making a ticking noise like an electric signal. but is that normal? sory no pics, public comp. w/o a pic program of any sort... thanks for the help...
