We see these relays go bad when people eliminate the plastic shield they were mounted on and just throw them on the inner fender. They have rubber boots to keep them dry which only work when they're on top.

I think i tracked the wire back to the AC Relay on the pax side of the engine bay. AC relay is corroded, bolts were heavily rusted, and a "tech" had wrapped electric tape around some of the wires. I remember who it was because he told me he "repaired" my ac relay when I had my coolant refilled. The cars been god awful for almost 18 months now, I really hope this is it. > > > > > > On Tue, Mar 25, 2008 at 10:26 PM, Bill Cardell <[EMAIL PROTECTED]> > wrote: > > > > > > > > > > > The ecu in an NB stands vertically above the driver's knees or calves. > Four multi connectors on it.
