Default Weak a/c?

Since we acquired or Ls 460 recently I have seemingly noticed the a/c’s fan output is too low.

Getting in ir warm the fan does not come on right away. Stays on barely on.

i have to manually turn the fan speed up for comfort a lot.

Car is black on black.

What do the rear seat side outlets put out?

i see blower motors have been replaced here from a few owners?

i have not checked the coolant charge yet. Could that be involved.

Thanks for any help.

I would say it needs a charge or something.

My A/C is very cold.

Hi bob....try changing the cabin air filter.may be the filter is accumulated with lot of dust.it is important to clean the cabin air filters in order to ensure smooth flow of air from the vents.

Also make sure you're not in ECO mode. AC functions are reduced to lessen the load on the engine and maximize MPG when in ECO mode.
