Default Help...rodent odor from vents

Looks like winter storage wasn't nice for me, but good for mice. When I run the ventilation system, I get the stench of mouse house from the vents. I've tried the odor bomb route, it helped but odor is still there. Where and how do I look in the vent/blower to find and remove whatever they left behind. thanks

First place to check is in the blower motor area......which involves dropping the motor......but if the nests are extensive, you may have to disassemble the dash. Good luck.

You might be able to start a little shallower on your mouse motel search by pulling the cowl vent and inspect the trough area all along the bulkhead. This entails pulling the windshield wipers (plastic nut caps, nuts, wipers, disconnect tubing for wiper washer nozzles and remove wiper blades from the drive spindles. If the wiper blades are stuck to the spindles, protect the area and try soaking the spindles first with a spritz of 1/2 lacquer thinner, 1/2 transmission fluid. Best ever for bustin’ corroded parts!) remove the push pins securing the plastic vent cover and as well the cover. Grab your source of illumination to view side to side all through the trough area.

Once the trough area of the bulkhead is opened and all possible foreign matter removed, look below the permanently affixed sheet metal plate on the passenger side over the trough. You should notice protruding ever so slightly into the trough area below this plate the rectangular fresh air intake for the HVAC system.

Inspect the intake opening using an angled mirror (this will require some Corvette Convolutin’, a skill well known to long time Corvette owners) to view down into the area above the blower motor. If you discover more debris in this process, then your efforts will be better served disassembling the interior area above the passenger foot well to gain access to the blower motor housing, remove the blower motor and evict those measly meeces.

If your fortunes run the way of some and the risk of vacancy notifications possibly spreading in the rodent kingdom, this is a good time to install a galvanized 1” metal garden mesh fashioned and attached to incorporate ‘fencing’ if you will over the HVAC intake opening at the cowl. Tedious process but well worth the ‘No Rodent Trespassing’ protection. Be creative, though. The ‘fencing’ doesn’t necessarily have to cover the specific vent opening, just restrict access through the bulkhead trough from both sides of the sheet metal cover. Don’t over complicate this as such is the manner of some (me, more specifically).

Hope that helps and good luck!

Is this a joke? Taking apart the cowl is significantly more time consuming then just dropping the blower motor.

I would not want lacquer thinner within 50ft of my corvette, let alone any plastic/painted surface. Not sure I understand the 1" garden mesh either, unless you are just trying to keep out rabbits.

Thanks for the input, gives me a good idea of what to try. I like the blower motor idea first and also trying to use a boroscope in the cowl area.

@barcalude …and @lucky131969 is more well known for his wealth of information and deeper levels of experience, although apparently limited. I wouldn’t back away from his expertise in those areas of ownership as he is well invested. A little salty at times, but credibly true to his nature.

About ten years ago I found two mice in my blower motor that had been centrifuged to a 90 percent enrichment level! That area is so well insulated I never got the smell until I opened it up. I could here something clunking and thought it was a bad bearing.
It's not hard to get to the blower. Just takes a little courage to pry on the plastic parts.

I bet you have mice in the blower!!

I think you're right, now it's starting to smell like something died in there...time to pull the blower!

You could hit it with an O-Zone generator overnight as a test.

Great option and it works very well, but the source needs to be found/removed first.
