Lately I’ve noticed my 2018 Tacoma has had a bad chemical smell coming out of the AC vents. It’s a chemical smell to me and I’ve had 2 other people say the same. Although at first it smelled like BO. I’ve checked under the hood for rodents, air filter, and cabin air filter. One other interesting detail, when driving on the highway with the air off the vents still blow unless I turn inside air on. Never though much of that before, but I wonder if it is relevant.... Any ideas of what to look for?
