I never knew the word guys was spelled with 'z', the word 'I' was spelled with a lower case letter and the word 'you' was represented by a simple yet incorrect spelling 'u'.From what I gather the fans are electric like most cars. This means there are only a few possible problems.It could the be the motors on the fans, however you said fans turn on when the A/C is on this eliminates the bad motor theory. The second problem could be wiring, however the motors come on with the A/C so this lowers the chance of bad wiring. Eliminating the above two problems leaves only two other possibilities, the thermostat or the computer. The computer is a possibility but unlikely if there are no other signs of computer failure. This leaves the thermostat.Personally I would replace the thermostat as they seem to be a problem device on may cars I have seen in my shop and they are cheap compared to other repairs. You could try cleaning the electrical contacts on the th thermostat but I feel this would not help much.Hope this helps
