    Recently, I have been having a problem with intermittent power loss to the left hand switch pod on my 1990 Auspec 300ZX NA. This means intermittent loss of aircon, fan speed and wipers in particular.

    I have not done any electrical work under the dasboard that may have triggered this issue

    Any thoughts on where best to start, before I start backtracking through the wiring with a multimeter?

    Thanks for any help.

    Looking at the FSM, they seem to be separate systems (nothing jumped out as a common link). So I would wonder if it's just the plugs in the back of the pod just not home properly from when ever it was last disconnected and now just loose enough to cause issue.

    That's a good idea to start with that.
    I will remove the switch pod and also spray some contact cleaner on that plug before pushing it back on.
    Thanks.

    Accessory relay, back of the bottom of the drivers side fuse box. Ask me how I know.

    I have sprayed contact cleaner on the connectors at the back of the left hand switch pod as well as the relay connectors on the main fuse bank in the engine bay. That appears to have solved the problem for now, but it's hard to know longer term when it's an intermittent fault.
    I didn't realise there was a further relay behind the fuse panel, so I will check that too. Thanks for pinpointing that.
    I think its a driver seat out job to be able to more easily get to the fuse panel and remove it.

    Anyone know where I can source a new blue accessory relay that sits behind the fuse box in the driver-side footwell?

    So long as it's the same pin layout and amp rating. It doesn't really matter the colour of the relay.
    Try your local automotive store Repco, Supercheap etc to see if they have something suitable <- though it would likely not be locking unlike the Nissan type. You could look on eBay too for Nissan types.
    This Sydney based website has Nissan relays http://www.larpro.com.au/larpro/Home

    Also try your local Nissan dealer's parts department.
