what year is the Es300?
....I work on 92 es300(my mom and dads)...i have done a few valve cover gasket replacements on these motors(same motor....as far as i know....as camary 92 V6) and advise that whoever does it will replace:
1. both valve cover gaskets
2. run a small bead of toyota(lexus?) black sealer around cam seals
(i think toyota service manuals recommends this also)
3. replace ALL the rubber gromets/washer for the 10mm or 12mm (its been awhile) bolts that hold down the valve cover
hope this helps alittle...

Have never had this problem before:
when ac is running, cold air only comes out the two center air vents. The other four vents are blowing "warm-ambient" air.
My guess is something to do with the air ducts behind the dashboard--->I don't want to take the dashboard out if not neccessary.
Any advice.....???
92 Es300:cold Air Only Coming Out Of Center Vents
in 92 - 06 Lexus ES250/300/330

it took me awhile but I finally got a chance to check out the ac problem again....
1. the motor for the vents are working ok...I can see(under driverside dashboard)/hear the motor moving when changing vent "modes".
2. I check for codes holding down auto and recirc....
a. the only numbers I saw were 00-flashing on the screen steadily
b. while in diagnostic mode I pressed the recirc again and it ran from codes "20-29" running all the test that it needed to properly...as far as I can tell.
3. I checked the reservoir "sight glass" while ac was running and I can see the "stream" of freon moving by without it clearing up. Isn't the stream suppose to clear up after a while or am I wrong?
My next step: Have a shop put dye in the system to check for leaks.
Any more advice? :D
