Both Port and STBD switched pads have failed on my 2007 310 DA. Port failed first then next day STBD switch failed ( strange). Unfortunately engine hatch switch is on the STBD switch pad with fuse panel located in engine compartment (?) After manually opening engine hatch, which is no easy task, new engine hatch switch was installed independent of Switch pads with fuse located under helm. Back to my issue: Has anyone experienced this issue ? Not sure how to test the EIM's ? Searay haven't been much help...
