Now we all know misting can be a problem, and after making sure the door membranes were present and correct ages ago, the misting still occurred.. usually after i'd used the air con.
Now my car has never had the air-con puddle under it, and following on from advice in Kaz's thread i thought i'd look at the heater box... so, as the rad was out, spare support bar was out and battery removed for charging, i delved slightly deeper and took out the heater blower to investigate the cooler matrix...
Kaz's general advice to clean it was well worth the effort. 17 years of dust, dirt, leaf material and seeds had done a good job of clogging things, not so much the matrix, but more the drain hole under the matrix... the one that lets the condensed water out from the front of the matrix. so the water condensed, drained to the bottom, and sat there nicely in a leaf mulch!!!
soapy water and a brush soon had the matrix clean, and a bit of careful digging and probing with a rod of solder had the drain clear! fingers crossed!!!
to prevent it happening again, a filter was required, so following on from here,
http://www.nsxprime.com/forums/showt...ht=hepa+filter i ordered a FRAM CA 9115 air filter (less than a tenner delivered off ebay) and set too....
the offending inlet...
where the filter fits...
i decided it didn't need trimming, as it fitted nice and snug as it was...
all done, just be careful refitting all the screws and the screen lower moulding
