I have a 95 camry v6 le and i have been having problems with the ac for about a year now. when i turn on the ac it will some times blow cold air for a little while and then it will blow air. other times it will not blow out cold air at all. i had it look at and the mechanic said that it was the solenoid behind the dash. does anybody know how hard it is to fix this, b/c if it is not extremely difficult i would do it my self and not spend the $400 for the mechanic to do it.
