My 2001 RX300 is only putting out moderately cool air when on MAX COOL now. I recently (Dec 2016) had to replace the HVAC Control Motor - Air Mix due to the original motor/servo failure and wonder if this could be again at fault.

The last regular dealer servicing (@ 120,000 miles) was in Sept 2016 when the AC cabin filter was replaced. Otherwise I see no record of other AC servicing recently.

I've had very helpful info from this site twice before and would appreciate suggested coruse of action/inquiry.

Thanks.

 

Have the low and hi pressure measured by a qualified technician.
