The R34 has panel type filters in the air conditioning duct, between the fan and the evaporator.
I do have it with detailed pictures in a word doc, but it is too big for an attachment on this forum. Text only to follow...............
R34 Air Conditioning Air Filters:
SAFETY>>>>>>>>>>>All yellow wiring is related to the AirBag System. If necessary, disconnect battery before starting work
The R34 model has 2 panel-type air filters, to ensure clean air is passed through the evaporator coils. (I haven’t seen this feature on any other car before.)
Like any other filter, they also need to be cleaned, so here is some info that might make it easier next time. (It’s like brain surgery………….., easy….. when you know how.)
1. Remove the passengers-side sill trim (lever up with screwdriver, attached in 4 places)
2. Remove passengers-side kick-panel (unscrew plastic nut on firewall stud, and lever front edge off with screwdriver, attached in 2 places.)
3. Pull off rubber door sealing strip to top of dashboard.
4. Remove glovebox, by:
a. Removing the 2 lower hinge pins (by sliding inwards to unclip). Partially remove the glovebox lid, being careful not to break the tension string.
b. Remove the screw at the lower RHS of the glovebox assy, as shown below.
c. Remove 4 screws along the top edge of the glovebox.
d. Remove the screw at the lower LHS of the glovebox.
e. Disconnect the Glovebox-light cable, and remove the entire assy. The car should look like this now…
f. Remove the black spring clip on the lower edge of the white vertical filter cover, and gently lift the cover upwards.
g. Remove the 2 panel filters by sliding out the lower one first, and then the top one will fall down.
h. Remove the white fibre concertina element (dust filter), from both panels, gently clean with compressed air, then wash in hot water and detergent.
i. Remove the black honeycomb element (deodorising filter), from both panels, and very gently clean with compressed air only.
If you clean these elements carefully, they can be reused, as I would hate to think what a replacement filter would be worth.
The filters on my car were absolutely filthy…a fine specimen of the air quality in Tokyo I suppose!
Assemble parts in the reverse order, but pay particular attention to the alignment pin above the screw, on the lower RHS of the glovebox assy. See Fig 1 above.
As with all plastic parts on cars, don’t use excessive force to remove or replace them.
Hope this helps any fellow R34 owners.
