Turned AC blower motor on high and got loud rumble. Turned blower off and then on and worked normal, until 2 days later got something smelling dead odor from air vents. Removed passenger side glove box and lower paneling. Opened flapper door above blower motor and vacuumed out parts of mouse nest, but unable to get the ducts apart to clean probable mouse remains. Smells BAd Bad!!
For 1992 LS 400

 

lol ur gonna need to nuke ur interior with a car deodorizer bomb.

 

Getting the ducts out is a real PITA. Did the 92 come with a cabin air filter? If so then you know it didn't get past that. To get the smell out, do this about 10 times. Take some Lysol, or Febreeze, or whatever and spray it in the air ducts outside at the bottom of the windsheild. Turn your HVAC to fresh air and on high. That will suck the spray through the vents. But ya still need to get the rodent out and there is alot of ducts going through the car, alot!!

 

find how it got in and you should be able to take it out. i'd start by checking from the cowl intake.
