CASE 650K A/C Stopped Working Need Help!?!

[SeaMac]

Hi all, it's been a while since I last posted. I'm running a CASE 650K -nice little dozer actually- and the A/C stopped working, fan blows but no cold air. Trekker -Case Dealer- came out and told us it had to go back to their shop -not happening- our own Mechanic thinks it's electrical and I'm inclined to agree. Does anyone know of a common electrical "issue" with this dozer and the A/C?

This is a Series 3 Dozer if this info helps.

Does the compressor run? Did you check the charge? Try to bypass psi switch

I'll check the compressor tomorrow, our Mechanic claims the charge is good. Thanks...

Had the Dealer's Technician check it out today, after nearly dismantling the entire interior he determined the electronic controller had gone south. New one's been ordered, should have properly functioning A/C next Tuesday. :thumbsup
