Intermittent heater and defogger operation

[riversz]

My 1971 Z has a problem with the heater and rear defogger only running intermittently. I traced it down to a relay on the kick plate on the passenger side of the car. Can this relay be repaired, it sounds like there are contact points inside or does it need to be replaced? By the way it gets constant power, it just doesnt always allow current to pass to either the heater or defogger. It always 'clicks' but no power is passed to the heater or defogger. Any ideas where I can get this relay? I doubt a Nissan dealer would have such an old part.

Thanks

Sounds like your Accesory relay. You might be able to get a new one from either Motorsports or Victoria British, or even a boneyard.
