The a/c on my 99 maxima works after pushing the A/C button several times. Once it begins working, it typically will continue throughout the trip. I've had it checked for leaks and don't think it is the compressor. Any suggestions? Is is possible that the switch has gone bad and can it be replaced or possibly a bad clutch?

 

Could be the sw or possibly the pcboard its sitting on, or its connectors. Try junkyards to find another... Seek via links below the detailed HowTo, seek until u find, everythin is there
