Quick Fixes for Common Problems with the Lexus GX470 Cabin Air Filter
There are two aspects to the Lexus GX470's air conditioning system-and all cars for that matter-the first is that it is supposed to keep things cool. That's the bit that few people are likely to miss-what with keeping cool all important today in a world of increasing global temperatures. The second, and less obvious, is that the air conditioning system is supposed to make sure that only clean air reaches you and your passengers inside your Lexus. This last bit is only really noticed when your senses are assaulted by smelly, noxious, and thoroughly dirty air. That's why it's important to watch for the signs that your cabin air filter is on the fritz.
Your cabin air filter primarily keeps solid particles out; particles like dust or tiny pebbles. If you notice that the air in your cabin is getting stuffy and "thick" with dust, it's likely that your air filter has failed miserably. Of course, the first step is to make sure you didn't just set your air conditioning unit to allow outside air in-that will let most particles in anyway. Once you're sure that it's set to internal air conditioning only, you can safely assume that it's most certainly the Lexus GX470 cabin air filter at fault. Technically, you can still repair your busted air filter-especially if the "damage" is just a clogged-up portion. Economically, however, it really is better to just replace the entire thing-that won't cost you much money anyway.
This is only partially a symptom of a failed cabin air filter because a number of things can stink up the air in your cab. For example, if an animal dies under the hood, that will cause a bad smell not tied to your filter. It does, however, allow you the chance to check your cabin air filter all the same. Sometimes, mud and dirt built up on your cabin air filter can rot-if it has any biological matter on it-and cause a stink. So, if the air smells bad, clean up your Lexus GX470 cabin air filter. That might take care of the stink. If it doesn't at least you've crossed the filter off the list.
