Aloha folks, my A/C after running well will not come back on after shut off for a 1/2 hour or so. The other day, it came on after 10-15 min. If I wait several hours it comes on fine. The mechanic mentioned several possible problems, one of which was low on Freon. I have had no trouble adding Freon to my Ford but this is a Lexus and am a little shy. Do you think it is worth a try or a poor diagnosis?
Thanks Ed
