Cabin Filters

Recommended Posts


I have recently purchased a second hand Lexus and love it.

My only issue is that the AC/heating has a funny stale smell to it.

Can anybody tell me why this may be? Would changing the cabin filter be the resolution?

Many thanks,

Yep, change the pollen filter, its behind the glovebox.

If the smell is still there, then you might need the help of a/c specialist.

gotta say, there was a thread about this a week or so ago and as i had the same smell, i brought a £11 can from Halfords, did what it said, and for a week it was great, but the smell is back now, this is after changing panel filter, cabin filter and the can. So im afraid i would say if its stinky, you need a pro to do it

I had the stinky A/C issue. I removed the cabin filter and put back the tray. Set the vents so that it comes out of everywhere (auto). Turned on the fan full blast with the A/C off. Squirted the deoderiser stuff into the outside air intakes in front of the windscreen. Repeated the squirting twice more. Switch the fan off and fit a replacement cabin filter. Leave for a few minutes to "dry out". Job done. I used the Wynn's stuff by the way.
