Narrative:

Switch panel and intercom failed during approach phase of flight. Received descent and heading to intercept, but transmission was broken. First officer (flying pilot) did not hear entire transmission. With hand signals I relayed clearance to first officer. While trying to troubleshoot communication problem, we went through the localizer, approach control questioned our actions, at which time I took control and returning aircraft for intercepting ILS. Upon switching to tower frequency no response till second call was made.
