Just like having a recirculation button on the AC when the top is DOWN! HUH?!?!?!
Yes I do drive with the AC on, when the top is down...but directed at my feet.

Biggest missing protection is a screen where air comes into the cabin. Yuk, last week killed two mice in garage, then car starts to stink, couple days ago with top down cause of the stink, I turn blower on through lower vents at 70mph and a ? load of mouse droppings. Come out lower passenger side. Did same thing again a little more come out. Still stinks, maybe still some nesting and poop stuck in the system. But if it did not get in there in the first place ?

Follow up to my rodent encounter in cabin vent.
If anyone stores there car and live in areas where small rodents can get into the engine compartment I would highly recommend doing this to prevent nests resulting in fowl odors. I ended up vacuuming from the engine access and from removal of the blower in passenger foot well. And yes, there is no filter, just a screen mesh to keep small leaves and such from entering the blower. Even if I did store with the vent closed, upon opening the nest would have dropped onto the so called filter. Opening and closing the vent pushed the poop past the screen/filter. Whom ever put the plastic trim over the vent had the right idea but did not complete it, its worthless without a screen. Glad it was there though otherwise I would have rigged up something terrible.
Upon removal of the plastic cowling and windshield wipers I find an open plastic trim around the vent:

Close up view down the vent, the nest is visible and dead mouse in there somewhere, I vacuumed this all out:

I removed the plastic trim, cleaned and added a Stainless Steel mesh to the underside, hot melt, zip ties and reused the foam weather strip that was existing. Added more foam to the snap ends to prevent the assembly from bowing.

Finished and in place, the way it should have been:
![72910]()
Now replace the cowling and wipers and done, knowing mice cannot get in anymore.
Some have been asking where to get the wire mesh:

Excellent write up! What would prevent adding some foam to the inlet and make the cabin fresh air filter to also filter something here? That would leave the built-in factory filter (mesh really) pretty much unnecessary.
Yes, it is a cabriolet but in my end I ride it for 6+ months roof on top.

Addition of a screen to the HVAC inlet
What is labelled as a side cowl grille, is in reality, a bezel desperately in need of a metal screen mesh to keep critters, leaves, twigs, etc. from finding their way into the cabin air blower fan,…

Mine has been giving a diminished air flow when it's set to get fresh air from outside, and normal airflow - much stronger - when set to recirculate. I came here looking for where the air cabin filter was to change it. I've changed it on many MANY cars in the past and it's usually 2 screws under the glove compartment or in some GM cars, a vent fin to remove outside, under the passenger's side windshield wiper.
Never have I seen this kind of abomination.
I'll just use recirculate. Thank you very much.

As far as I understand, 124 Spiders and recent MX-5s do not use cabin air filters. There is a mesh where the filter used to go. You can use a vacuum to clean debris over the mesh from the engine side of the air intake, as described a few posts earlier. That's what I did, and I also used the poster's idea of adding a front mesh at the air intake to prevent critters from nesting in there.

Correct, and yet were the dealers not looking to charge multiple hours to do it?
