1994 Lexus Ls 400

[Larry W]

Is there a cabin a/c filter for this year LS? How do I service it? How do you know when it's time to replace it?

The 93-up LS400 has cabin filters. Instructions on how to replace the filters on a 93-94 LS400 are at the bottom of this thread: http://us.lexusownersclub.com/forums/index...l=cabin++filter

It looks like this diagram shows the filters: http://www.toyodiy.com/parts/p_U_1994_LEXU...EPGKA_8714.html

The cabin filters on a 95-up LS400 are in a different place.

When to replace it? I think the maintenance schedule for my 00 LS says to replace the cabin filter every 30K miles although sometimes I just remove it and knock the dirt and junk out of it. Does the maintenance schedule for your 93 LS have a replacement schedule? I think the instructions for my car say something about blowing the dirt out with compressed air. Some people have cut up furnace filters to use as replacement filters -- don't know if that would work for a 93-94.

There should be a removable section on the back of the inside of the glove compartment. Take it out, and the filter is located right behind it.

The filter on the '93-'94 cars is through the passenger-side lower dash panel, directly under the glove box. It's a long, curving panel that goes back to the firewall almost. Careful with the clips; they're easily broken. My sister's '93 has the panel attached with huge lag screws that some idiot who snapped the clips used to "repair" the panel. Ugly as sin! And they're hard to find at the boneyards for some reason.
